The GTM data API · one price, no credits
Search, enrich and verify people and companies through one REST API — and a hosted MCP server, so Claude, ChatGPT and your own agents can do it themselves. One price, no CRM to migrate to, no seats to buy and no credits to top up.

Real commands from our docs. Records shown are samples, not real people.
Unified from 20+ data sources into one schema — one key, one shape, no vendors to stitch together yourself.
Works where you work
LeadOcean runs a hosted MCP server. Add it once, sign in with your account, and your assistant can find, enrich and verify people and companies while it works — usage billed to your plan, not to a key you pasted into a chat. Everything the tools do is available over plain REST too.
Add LeadOcean as a custom connector in Claude web, desktop or mobile, then search and enrich inside any conversation.
Set upTurn on developer mode, add the MCP server URL, approve the sign-in, and give your GPTs fresh B2B data.
Set upClaude Code, Cursor, Codex, VS Code, Windsurf and Gemini CLI all connect over remote MCP with one line of config.
Set upThree REST endpoints, one JSON schema, cursor paging. Call it from a script, a workflow, a warehouse job or your product.
Set upWho it is for
LeadOcean is an API and a set of tools for agents. If your pipeline lives in scripts, workflows and prompts rather than in someone else's interface, this is the data layer for it.
Build lists, enrich records and keep fields fresh from your own jobs — on your schedule, in your warehouse, with your logic.
Find the exact segment: title, seniority, country, industry, company size, domain. Verify the email before you ever send.
Give an agent the seven MCP tools and it finds, qualifies and enriches on its own — inside Claude, ChatGPT, Cursor or your product.
One key, many clients. Predictable JSON, cursor paging and a schema that stays stable while you scale delivery.
Build once, use anywhere
Search people, enrich a person, look up a company. Structured, predictable JSON that code and models both read well — plus llms.txt, so an assistant can learn the entire API in a single fetch.

}Everything you need
46+ ICP filters across people and companies — title, seniority, industry, headcount, revenue, funding, tech and location — unified from 20+ sources. Cursor paging to the end of the segment, not the first page of it.
A LinkedIn URL or an email becomes a full record: current role, company firmographics, work history, skills, education, location.
Deliverability status on every email, and reveal the address only when you actually need it — so a bad list never costs you twice.
Seven self-describing MCP tools plus a complete llms.txt reference, so a model can plan and run the work without you writing glue.
From incomplete to AI-ready
Send what you have — an email or a LinkedIn URL. Get back a structured record with the context your play needs to run, and nothing invented: unknown fields come back null instead of guessed.
Simple, transparent pricing
Every account starts free with 1,000 records a month and no card. Go to production and one plan covers everything, without a meter you have to watch: unlimited searches, enrichments and lookups. No credit packs, no per-record pricing, no overage invoices, no sales call.
