--- title: "Lead411 competitors, by reason for leaving" description: "Lead411 alternatives ranked by why teams actually switch, with verified pricing and the trade each one makes." url: https://frontal.so/gtm-apis/alternatives/lead411-alternatives updated: 2026-11-12 --- Alternatives · Verified 24 Oct 2026 # Lead411 competitors, sorted by *why you are leaving* Lead411 prints a price for its API plan and nothing about the API itself. Most teams weighing Lead411 competitors want an API they can read before they pay, and a price they can see without a call. 4 replacements below, each one matched to a specific reason. Short answer If you want the same whole-contact export with a documented API, RocketReach is the closest of these Lead411 competitors, and its per-export price falls to $0.085 on Ultimate. If emails are most of the job, Apollo at $0.0196 a credit and Lusha at $0.087 are both cheaper per address than a $0.15 Lead411 export, and both let you test the API on a free plan. ZoomInfo is the one to price if Lead411 was only ever the cheaper quote against it. If your lookups need the direct dial at low volume on monthly billing, Lead411 Ignite may still be cheaper per dial than any pick here, though its $150 is a starting price quoted by team size and features, so ask for its API terms before you leave. Prices and limits for every option below are read off the vendor's own page. These are the Lead411 alternatives that each answer a named problem. See the 4 alternatives [Visit Lead411](https://www.lead411.com/) replacements.txt 4 picks rocketreach **$33/mo annual** apollo **$49/seat/mo** lusha **$37.45/mo annual** zoominfo **$0.38/data credit** Currently on $49/mo Diagnose first ## The 3 reasons people actually leave If none of these is your situation, the honest answer is that you should probably stay. The 23 providers in the [Enrichment APIs](https://frontal.so/gtm-apis/enrichment-apis) listing are where these replacements come from. ### 1 · There is no API reference to read Lead411 publishes no endpoints, no authentication method and no rate limits. Its homepage describes a developer-friendly Lead Enrichment API and links it to the pricing page, so the first look at a request comes from sales. That is the most common reason to look at Lead411 alternatives: an engineer cannot estimate the build, and an agent has nothing to call. ### 2 · The $49 plan does not carry the API Spark is $49 a month for 1,000 exports, $0.049 each, and its feature list has no API access. The first plan that lists it is Ignite, from $150 a month for 1,000 exports, so the programmatic floor is three times the headline price. Annual billing moves both down, to $490 and $1,500 a year, without changing the gate. ### 3 · "No data caps" is true of one quoted plan The pricing FAQ says Lead411 has no data caps or daily limits, but Spark and Ignite both carry monthly export allowances, and Ignite's 1,000 is a floor with a starting price. Unlimited exports belong to Blaze, which is annual and quoted. Above the published tier, the bill is a conversation. The alternatives ## 4 Lead411 alternatives, and what each one fixes Ordered by how closely each one answers the reasons above, not by price. | Provider | Entry price | Unit cost | Free tier | Best for | | --- | --- | --- | --- | --- | | [Lead411](https://www.lead411.com/) | $49/mo | $0.15 per export, at Ignite's starting price | 7-day free trial with 50 exports. No ongoing free tier, and the trial lists no API access. | Baseline | | [RocketReach](https://frontal.so/gtm-apis/enrichment-apis/rocketreach-api-review) | $33/mo annual | $0.25 per export on Pro, the first plan with phones | A free account gets 5 lookups, no card. No ongoing free tier. | API and MCP on the cheapest paid tier | | [Apollo API](https://frontal.so/gtm-apis/enrichment-apis/apollo-api-review) | $49/seat/mo | $0.0196 per credit | Free plan with API access, 900 credits per seat per year granted monthly, so 75 a month | Best all-in-one GTM API | | [Lusha](https://frontal.so/gtm-apis/enrichment-apis/lusha-api-review) | $37.45/mo annual | $0.087 per credit | Free plan, 40 credits a month, 1 seat, no card. API is rate limited strictly. | Best published credit costs for contact data | | [ZoomInfo](https://frontal.so/gtm-apis/enrichment-apis/zoominfo-api-review) | $0.38/data credit | $0.38 per data credit | 1,000 data and 1,000 AI credits at signup, no card. Credits expire after 12 months. | Enterprise depth, now with a self-serve API | Read from each vendor's own pricing page on 24 October 2026. In detail ## The case for each one Each one below is matched to a reason rather than scored, and each one names what you give up by taking it. A replacement with no downside is a replacement nobody has actually run. ### RocketReach The same whole-contact export, with the API and an [MCP server](https://frontal.so/gtm-apis/mcp-servers) on every paid plan and rate limits it actually publishes. [RocketReach](https://frontal.so/gtm-apis/enrichment-apis/rocketreach-api-review) sells exports the way Lead411 does, and on Pro and Ultimate an export carries the email and the phone together. Pro is $75 a month billed annually, $899 a year for 3,600 exports, so $0.25 an export. Ultimate is $1,699 a year for 20,000, so $0.085, which undercuts Lead411's $0.15 Ignite export at volume. The API and the MCP server are on all three paid plans, including Essentials at $33 a month billed annually, which is email only. The key comes from Account Settings and the MCP server at mcp.rocketreach.co/mcp signs in with OAuth 2.1 and PKCE. That is the integration surface Lead411 does not publish. The rate limits are written down per plan: 15 person lookups a minute and 500 a day on Essentials, up to 100 a minute and 3,000 a day on Ultimate, under 10 requests a second throughout. You can size a backfill against those numbers before you sign, which is not possible from Lead411's public pages. #### What you give up Monthly flexibility and the low-volume phone rate. RocketReach exports are annual allowances, Essentials is email only, and on Pro an export with a phone is $0.25 against Lead411's $0.15 at Ignite's starting price. There is no ongoing free tier beyond 5 lookups. #### When it is the wrong answer A small team that needs direct dials on monthly billing, where Lead411 Ignite is cheaper per contact and asks for no annual commitment. [Read the review](https://frontal.so/gtm-apis/enrichment-apis/rocketreach-api-review) ### [Visit Apollo](https://go.frontal.so/apollo) Apollo API The cheapest email on this page at $0.0196 a credit, a free plan with full API access, and sequencing behind the same key. Basic is $49 a seat a month billed annually, with 30,000 credits a seat a year, 2,500 a month, at $0.0196 each. An email is 1 credit, so an address costs about an eighth of a $0.15 Lead411 export. A mobile that comes back costs 9 credits, $0.1764, so a contact that needs the phone costs more than a Lead411 export does. The free plan carries full API access rather than a trial of it: 900 credits a seat a year, granted as 75 a month. The key goes in the x-api-key header, and the limits are published, 200 requests a minute, 400 an hour and 2,000 a day on Basic with enrichment at 1,000 a minute and no hourly or daily cap. [Apollo](https://frontal.so/gtm-apis/enrichment-apis/apollo-api-review) also covers more of the job than Lead411 does. It runs people and organization search on its own database, enrichment, and sequence, contact and task endpoints that cost 0 credits, all behind one key, and an MCP server at mcp.apollo.io/mcp for agent clients. #### What you give up A price that ignores seats and the cheap direct dial. Apollo grants credits per seat per year, Organization carries a three-seat minimum at $357 a month, and a mobile at $0.1764 costs more than a whole Lead411 export. #### When it is the wrong answer A dialing motion where every row needs the direct dial, and a headless pipeline that would pay a seat price with nobody logged in. [Read the review](https://frontal.so/gtm-apis/enrichment-apis/apollo-api-review) ### Lusha A free plan with API access, so you can measure a match rate before paying, and a rate card that prices every field. [Lusha](https://frontal.so/gtm-apis/enrichment-apis/lusha-api-review)'s free plan is 40 credits a month on one seat, no card, with API access that Lusha describes as strictly rate limited. It is enough to test your own rows before any money moves. Lead411's 7-day trial gives 50 exports but lists no API access. Every operation has a stated price: an email is 1 credit, a phone number 5, a recorded call 8, at $0.087 a credit on Pro, $52.45 a month billed yearly for 600 credits a month with full API access and webhooks. An email is therefore cheaper than a Lead411 export, and an email plus a phone, at about $0.52, is more than three times one. The integration is documented: an API key from the dashboard in the api\_key header, and an MCP server for agent clients. Credits on Pro roll over up to twice the monthly cap, which is a narrower rule than Lead411's rollover on every plan. #### What you give up The cheap phone and any published throughput. A direct dial is 5 credits, $0.437, and Lusha meters per plan across minute, hour and day windows without publishing the numbers. #### When it is the wrong answer Direct-dial volume, where the per-field rate card costs several times a Lead411 export. [Read the review](https://frontal.so/gtm-apis/enrichment-apis/lusha-api-review) · [Lead411 vs Lusha](https://frontal.so/gtm-apis/compare/lead411-vs-lusha) ### ZoomInfo The incumbent Lead411 prices itself against, now with a pay-as-you-go API: 1,000 free data credits, then $0.38 a credit, with search free. Lead411 sells against [ZoomInfo](https://frontal.so/gtm-apis/enrichment-apis/zoominfo-api-review) directly. Its pricing page offers to match or beat most enterprise competitor quotes, and its FAQ answers what makes it different from ZoomInfo or Apollo. If Lead411 was only ever on your list as the cheaper quote, ZoomInfo now has a self-serve price to compare it with. ZoomInfo's GTM AI route gives 1,000 data credits and 1,000 AI credits at signup with no card, then sells data credits at $0.38 each at the $1,000 spend tier. Search and lookup are free, and enriching a record costs one credit. Authentication is OAuth 2.0, with client credentials for server jobs, and self-serve runs at 5 requests a second. The free tier includes the API, an MCP server at mcp.zoominfo.com/mcp and a CLI, for up to 5 apps. Credits expire 12 months after they are granted, so the free allowance is a real evaluation window rather than a permanent tier. #### What you give up Price per record and the phone. At $0.38 a credit an enriched record costs more than twice a Lead411 export, and mobile numbers are Enterprise only, which is a quote. #### When it is the wrong answer A budget-led team that wants direct dials, where Lead411 Ignite is both cheaper and includes the dial. [Read the review](https://frontal.so/gtm-apis/enrichment-apis/zoominfo-api-review) Plan by plan ## What you would actually pay, on each one Every provider on this page publishes a rate card, so the real numbers can sit next to each other rather than behind a summary. The plan you want is the one whose included volume covers a normal month for you, not the cheapest one on the page. ### Lead411 Lead411 publishes 4 tiers, one of them a free trial, and the paid ladder runs from $49 to $150, with a quoted tier above it. #### Free trial $0 7 days, 50 exports - Verified emails and direct dials - Chrome extension - No API access listed #### Spark $49 /mo, 1,000 exports - $490 a year billed annually, for 12,000 exports and buyer intent - $0.049 an export at the monthly rate - CRM customizations and the Chrome extension, no API #### Ignite $150 /mo and up, from 1,000 exports - The cheapest plan that lists API access - $0.15 an export at the published starting price - $1,500 a year billed annually, flexible exports, intent as an add-on - Multiple users with admin control #### Blaze Quote annual billing only - Unlimited exports a year - API access, custom onboarding, optional buyer intent ### RocketReach RocketReach publishes 3 tiers, none of them free, and the paid ladder runs from $33 to $141.58. #### Essentials $33 /mo billed annually, $399 a year - 1,200 exports a year, email only - Unlimited verified personal and professional emails - MCP and API access #### Pro $75 /mo billed annually, $899 a year - 3,600 exports a year, email and phone - Technographics, news and org charts - Salesforce, Outreach, HubSpot and Salesloft integrations #### Ultimate $141.58 /mo billed annually, $1,699 a year - 20,000 exports a year, email and phone - Intent data and healthcare data - Salesforce custom mapping ### [Visit Apollo](https://go.frontal.so/apollo) Apollo API Apollo publishes 4 tiers, one of them free, and the paid ladder runs from $49 to $119. #### Free $0 900 credits a seat a year - Full API access, not a trial of it - Granted monthly, so 75 credits a month in practice - 2 sequences and basic filters #### Basic $49 /seat/mo billed annually, 30,000 credits a seat a year - $588 a seat a year, credits granted upfront and pooled across the team - 2,500 credits a month, at $0.0196 each - Annual billing saves 24% against paying monthly #### Professional $79 /seat/mo billed annually, 48,000 credits a seat a year - 4,000 credits a month, at $0.0198 each - AI lead scoring and multi-touch outreach #### Organization $119 /seat/mo billed annually, minimum 3 seats - 72,000 credits a seat a year, so 6,000 a month - $0.0198 a credit, so the rate is flat across every paid tier - The three-seat minimum makes $357 a month the real floor ### Lusha Lusha publishes 5 tiers, one of them free, and the paid ladder runs from $37.45 to $299.95, with a quoted tier above it. #### Free $0 /month - 40 credits a month, 1 seat - No credit card required - API access, but strictly rate limited #### Starter $37.45 /mo billed yearly - 4,800 credits a year, granted up front - 1 seat. Works out at $0.094 a credit - API still strictly rate limited #### Pro $52.45 /mo billed yearly - 7,200 credits a year, at $0.087 each - 2 free seats, full API, webhooks, CSV enrichment - Credits roll over to twice the monthly cap #### Premium $299.95 /mo billed yearly - 40,800 credits a year, at $0.088 each - 5 free seats, API Advanced, team management - Credit allocation across the team #### Scale Quote only - Custom annual credit volume - SSO and a dedicated customer success team - No rollover: the cap does not apply ### ZoomInfo ZoomInfo publishes 3 tiers, one of them free, and pay as you go with no minimum above the free allowance. #### Free $0 once, at signup - 1,000 data credits and 1,000 AI credits - API, MCP and CLI access, up to 5 apps - 5 requests a second, no card #### Pay as you go $0 upfront, then $0.38 a data credit at the $1,000 tier - Top-ups from $20, no contract and no seat fees - AI credits a flat $0.05 each - Credits expire 12 months after they are granted #### Enterprise Custom annual volume - Mobile phone data and records under management - Custom rate limits, SSO and SAML - SLA-backed support and an audience waterfall across 25+ vendors Read the included volume before the headline price. A plan that costs twice as much and carries five times the credits is the cheaper plan, and on this page that is the usual case rather than the exception. Cost model ## What each one costs at your volume Lead411 first, then every replacement. The model picks the cheapest published plan that covers your volume on each one, which is the comparison a row of entry prices cannot make. ### Lead411 Priced on the volume you use, so the plan that covers a normal month is the one that decides the bill. Plan that covers it **Past the published ladder** Largest published **Ignite, 1,000 exports** At your volume **Quoted** Ask for **the per-export rate above 1,000** ### RocketReach Priced on the volume you use, so the plan that covers a normal month is the one that decides the bill. Plan that covers it **Past the published ladder** Largest published **Ultimate, 1,667 exports** At your volume **Quoted** Ask for **the per-export rate above 1,667** ### [Visit Apollo](https://go.frontal.so/apollo) Apollo API Priced on the volume you use, so the plan that covers a normal month is the one that decides the bill. Plan that covers it **Basic, 4 seats** Monthly **$196** Twelve months **$2,352** Included **10,000 credits** Your rate at this volume **$0.0196 per credit** ### Lusha Priced on the volume you use, so the plan that covers a normal month is the one that decides the bill. Plan that covers it **Past the published ladder** Largest published **Premium, 3,400 credits** At your volume **Quoted** Ask for **the per-credit rate above 3,400** ### ZoomInfo Priced on the volume you use, so the plan that covers a normal month is the one that decides the bill. Plan that covers it **Pay as you go** Monthly **$3,800** Twelve months **$45,600** Included **$0.38 per data credit, nothing up front** Your rate at this volume **$0.38 per data credit** Plans are read from each vendor's own pricing page and the model picks the cheapest one that covers you, so these are list prices on the billing term each vendor publishes, annual where that is how it prices, before any discount you negotiate. Twelve months ## What a year costs at three volumes The same plan-fit arithmetic as the model above, run out to a year, because an annual number is what a budget actually asks for. Every column moves with volume, through a bigger plan or more seats. | A year at | Lead411 | RocketReach | Apollo API | Lusha | ZoomInfo | | --- | --- | --- | --- | --- | --- | | 1,000 a month | $1,800 Ignite | $1,699 Ultimate | $588 Basic | $3,599 Premium | $4,560 Pay as you go | | 10,000 a month | Quoted | Quoted | $2,352 Basic | Quoted | $45,600 Pay as you go | | 50,000 a month | Quoted | Quoted | $11,760 Basic | Quoted | $228,000 Pay as you go | These are list prices on the published plan that covers each volume, on the billing term each vendor publishes, so they are the number before you negotiate. Decide ## Which replacement is yours Answer what matters most and the lean appears below. Every option is read from the records on this page, and staying on Lead411 is one of the possible answers. What matters most on the thing you are replacing? Have you measured what you have today? Answer the questions above Each answer leans one way. The recommendation appears here once you have picked at least two. A tool like this can only weigh what is on the page. It does not know your workload, and the one test that does is the bake-off on this page: your own rows, queries or records, run on the cheapest entry each side offers. Where an answer leans on a certification or an integration, it means that vendor publishes it on the pages this directory read, which is not the same as the other one lacking it. The sources are listed at the foot of the page. Provenance ## Where the data comes from, and what you may do with it The question that arrives late and expensively is who is allowed to hold the data. A migration is the moment to check it, because you are signing a new contract anyway. | Provider | Fields returned | Coverage | Compliance | Redistribution | | --- | --- | --- | --- | --- | | [Lead411](https://www.lead411.com/) | Work email, Mobile phone, Firmographics, Technographics, Intent and news, Job postings | Global | CCPA | Not stated | | [RocketReach](https://frontal.so/gtm-apis/enrichment-apis/rocketreach-api-review) | Work email, Personal email, Mobile phone, Firmographics, Technographics, Intent and news | Strongest in NA | CCPA | Not stated | | [Apollo API](https://frontal.so/gtm-apis/enrichment-apis/apollo-api-review) | Work email, Mobile phone, Firmographics, Technographics, Job postings, Intent and news, LinkedIn profile, CRM records | Global | GDPR DPA SOC 2 Type II CCPA | Not stated | | [Lusha](https://frontal.so/gtm-apis/enrichment-apis/lusha-api-review) | Work email, Mobile phone, Firmographics, Technographics, Intent and news, Job changes | Global | GDPR DPA CCPA | Not stated | | [ZoomInfo](https://frontal.so/gtm-apis/enrichment-apis/zoominfo-api-review) | Work email, Mobile phone, Firmographics, Technographics, Intent and news, Job changes | Strongest in NA | GDPR DPA CCPA | Not stated | None of these states a redistribution position on its pricing or docs pages. Internally that never matters. Put the rows in something your customers can see and it becomes the question your legal team asks first. Two practical notes that apply to every provider on this page. A compliance badge describes the vendor rather than your use of it, so a GDPR DPA does not give you a lawful basis for the outreach you send. And every one of these vendors runs its own opt-out, which means a person who asks you to delete their record has to be removed from your copy as well as from theirs. Migration ## Moving off Lead411 Written against RocketReach, the first pick above, because the steps are the same whichever one you take and the specifics are what make them useful. Swap the name and the order still holds. 01 ### Measure the thing you are about to lose Run 500 rows you already have through Lead411 and record the match rate, the fields that came back populated and the cost. Without that number a migration cannot be judged, because every provider looks cheaper per unit than the one you are paying for today. 02 ### Check which fields change RocketReach does not return job postings, which Lead411 does. If anything downstream reads that field, the switch changes your pipeline as well as your vendor. 03 ### Rewrite the auth and the limits, in that order Lead411 publishes no authentication method. Lead411 has no public API reference; access is set up with Lead411 on the Ignite or Blaze plan. RocketReach uses an API key from Account Settings; the MCP server uses OAuth 2.1 with PKCE. The limits are the part that bites later. Lead411's limits: not published. Lead411 says there are no data caps or daily limits, which describes exports rather than request rates. RocketReach's limits: per plan: 15 person lookups a minute and 500 a day on Essentials, to 100 and 3,000 on Ultimate, under 10 requests a second. A loop tuned to the first will either crawl or get throttled on the second. 04 ### Run both for one billing cycle Keep the old key live and route a slice of real traffic to the new one. A month is the shortest honest test, because credit expiry, rollover and the overage rate only show up at renewal and those are where the surprises live. 05 ### Cancel on the renewal date Credits on most of these plans do not survive a downgrade. Check what happens to the balance you have already paid for, and time the switch so you are not buying the same records twice. The step people skip is the first one, and it is the only one that cannot be done after the fact. Once the old key is off you have nothing to compare the new match rate against, so a provider that is quietly worse on your segment looks like a provider that is fine. What practitioners say ## What practitioners say about Apollo The one part of this page that is not a vendor claim. The comment below makes its point in crude words, so we summarize it in our own words and link the thread. A Reddit claim is a signal rather than a fact, so nothing here is the only source for a figure on this page. ### The rate limit, not the credit price, is what people actually hit **In our words:** A practitioner building on the API says the rate limits are what their team hit, that they got past them by routing requests across three Apollo accounts, and that Apollo charges per request even when a lookup returns nothing. [r/gtmengineering](https://www.reddit.com/r/gtmengineering/comments/1toiu1u/apollo_api_limits/) · May 2026 · summarized rather than quoted Two halves worth separating. The limit is real and it is on this page: 200 requests a minute, 400 an hour and 2,000 a day on Basic, with enrichment on a separate 1,000 a minute and no hourly or daily cap. That split is why a bulk job and a per-row loop feel like different products. The charge-on-no-output half needs care, because Apollo publishes 0 credits when nothing is found and that matches what we read. What a miss does spend is a request against the rate limit, and when the limit is the binding constraint that is the cost you feel. Pooling accounts to get round a published limit is a terms question before it is an engineering one. 11 threads read on 13 October 2026, searched by vendor name. Scores and dates are the comment's own. Nothing here is the only source for a price or a limit on this site: every figure in the tables above comes from a vendor's own page. Verdict ## Should you actually switch? The short answer is at the top of this page. Before you act on it, run the test below, because it is the cheapest way to find out whether that answer holds for you. Before you migrate anything No provider in this category publishes a match rate you can hold them to, so run the same 500 rows through a free tier, a trial or a small paid top-up on each, verify every result set, and divide spend by survivors. Your own list is the only evidence worth acting on, it takes half a day, and it changes the decision often enough to be worth it.

FAQ ## Switching from Lead411, answered **What is the best Lead411 alternative?** It depends on why you are leaving, which is how this page is organized rather than ranked. The first pick here is RocketReach, which this directory sums up as "API and MCP on the cheapest paid tier", at $33/mo annual. The case for it, and what you give up, is in the section above. **Is there a free alternative to Lead411?** Yes, 3 of the replacements here do. Apollo: Free plan with API access, 900 credits per seat per year granted monthly, so 75 a month. Lusha: Free plan, 40 credits a month, 1 seat, no card. API is rate limited strictly. ZoomInfo: 1,000 data and 1,000 AI credits at signup, no card. Credits expire after 12 months. **How were these competitors chosen?** By the reason teams leave, not by a score. The page opens with the reasons teams leave and matches a replacement to each one.
