Headers: IETF RateLimit-\* plus X-RateLimit-\*. ## How to get an API key LeadMagic uses API key. The steps below follow LeadMagic's own docs. 1. Create a LeadMagic account. API access starts on the Essential plan. 2. app.leadmagic.io account settings, API keys page (issued immediately after choosing a paid plan) 3. Send it with every request: header X-API-Key (key starts with lm\_; header name case-insensitive). Hosted MCP and CLI use OAuth instead. 4. Make a first call: Work email from name + company. Keep the key in an environment variable, never in the command. ``` curl -X POST "https://api.leadmagic.io/v1/people/email-finder" \ -H "X-API-Key: $LEADMAGIC_API_KEY" \ -H "Content-Type: application/json" \ -d '{}' ``` ## Where the docs live What Where Documentation [leadmagic.io/docs/v1/introduction](https://leadmagic.io/docs/v1/introduction) API reference [leadmagic.io/docs/api-reference](https://leadmagic.io/docs/api-reference) OpenAPI spec [leadmagic.io/openapi.json](https://leadmagic.io/openapi.json) llms.txt [leadmagic.io/docs/llms.txt](https://leadmagic.io/docs/llms.txt) Changelog [leadmagic.io/docs/changelog](https://leadmagic.io/docs/changelog) Base URL `https://api.leadmagic.io` MCP server `https://mcp.leadmagic.io/mcp` SDKs lm-tui CLI (lm command, browser OAuth), OpenAPI 3 spec ## Strengths and limits ### Where it fits - Cheap email validation (0.25 credits per definitive result, unknown is free) - Email finder early in a waterfall where its find rate stays high - Mobile numbers at 5 credits per hit - Async bulk enrichment of large lists (up to 500,000 rows per job) with progress streaming - Unmetered people/company/job search on Professional and Ultimate plans - Agent workflows through a hosted MCP with 100+ tools and free cost preview ### Where it falls short - Last-resort slot in a waterfall: terms let LeadMagic throttle or suspend accounts whose sustained find rate drops below 10% - Reselling or embedding data in a product (self-serve plans are internal use only) - Buyers who need SOC 2 or ISO 27001 (LeadMagic states it holds neither) - Free testing: there is no free trial; a paid plan is required at signup ### Worth knowing - Fair-use clause: if sustained find rate falls below 10% (explicitly including use late in a waterfall or on exhausted lists), LeadMagic may throttle, suspend, change credit consumption or require a custom contract, regardless of prepaid credits. - Hosted MCP is OAuth only; static API keys in MCP config headers are not supported on production. - Annual and custom deals do not roll over credits. Monthly plans cap the total wallet (subscription + top-ups) at 2x the monthly allotment; excess follows expiry dates, and a downgrade recalculates the cap immediately. - Self-serve plans are internal use only: no resale, embedding or showing results to your clients. - Search endpoints never return emails or phones; legacy contact-detail flags return 400. Pay separately via Email Finder / Mobile Finder. 5 moreShow fewer - Validation bills instant 'invalid' results (syntax, no-MX, disposable, blocklisted) at 0.25; only 'unknown' is free. - 402 org\_closed means the subscription ended; buying credits or rotating keys does not fix it, and repeated retries pause the key with 429 for up to 24 h. - Past-due payment freezes the account immediately (API, CLI, MCP and dashboard). - MCP tool credit tables differ from REST in places (e.g. b2b\_profile\_to\_work\_email listed at 1 credit vs REST profile-to-email at 5; find\_company\_employees 1/person vs REST employee-finder 0.05). Check preview\_cost. - Team access beyond the included table seats requires a $499+ plan and $49 per seat per month. ### Our take LeadMagic's email finder comes right after Hunter in the email chain of an enrichment service we built for a B2B data company, and the service also calls its mobile finder. ## Who should use it Use LeadMagic for Cheap email validation (0.25 credits per definitive result, unknown is free) Look elsewhere for Last-resort slot in a waterfall: terms let LeadMagic throttle or suspend accounts whose sustained find rate drops below 10% ## If LeadMagic is not the answer Other Enrichment tools in this directory, each with its own review.

Free tier: None. No free trial or free-credit program. - **Keep the key out of your code**API key. It is sent as: header X-API-Key (key starts with lm\_; header name case-insensitive). Hosted MCP and CLI use OAuth instead.. - **Design around the rate limit**Per-endpoint per-minute limits: Email Finder and Email Validation 600 req/min (~10 req/s burst, ~50 in flight); most other endpoints 300 req/min; Company Search v1, Profile Search, Jobs Finder and metered Company Search v3 100 req/min. - **Know the catch before you scale**Fair-use clause: if sustained find rate falls below 10% (explicitly including use late in a waterfall or on exhausted lists), LeadMagic may throttle, suspend, change credit consumption or require a custom contract, regardless of prepaid credits. ## Want us to build it for you?
