Works where you work

Works inside Claude, ChatGPT and whatever you build

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.

Claude

Add LeadOcean as a custom connector in Claude web, desktop or mobile, then search and enrich inside any conversation.

Set up

ChatGPT

Turn on developer mode, add the MCP server URL, approve the sign-in, and give your GPTs fresh B2B data.

Set up

Agents and IDEs

Claude Code, Cursor, Codex, VS Code, Windsurf and Gemini CLI all connect over remote MCP with one line of config.

Set up

Your own stack

Three REST endpoints, one JSON schema, cursor paging. Call it from a script, a workflow, a warehouse job or your product.

Set up

Who it is for

Made for the people who build GTM, not the ones who buy seats

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.

RevOps and GTM engineers

Build lists, enrich records and keep fields fresh from your own jobs — on your schedule, in your warehouse, with your logic.

Outbound and demand gen

Find the exact segment: title, seniority, country, industry, company size, domain. Verify the email before you ever send.

AI and agent builders

Give an agent the seven MCP tools and it finds, qualifies and enriches on its own — inside Claude, ChatGPT, Cursor or your product.

Agencies and data teams

One key, many clients. Predictable JSON, cursor paging and a schema that stays stable while you scale delivery.

Build once, use anywhere

A simple API for powerful workflows

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

Everything a GTM team needs from a data layer

Search 700M+ profiles

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.

Enrich anything you have

A LinkedIn URL or an email becomes a full record: current role, company firmographics, work history, skills, education, location.

Verify before you send

Deliverability status on every email, and reveal the address only when you actually need it — so a bad list never costs you twice.

Tools your agent can drive

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

Turn thin rows into complete records

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.

What unlimited means here

No credits to buy, no per-record price, no overage invoice and no data locked behind a higher tier — every plan reaches the whole database. Throughput is paced at 100 requests a second per key. If a production workload needs more headroom than that, email us and we raise it.

Not a CRM. On purpose.

Nothing to migrate, nobody to onboard. LeadOcean sits under the tools you already use and gets out of the way.

Questions

Frequently asked

How big is the database?
More than 700 million people profiles and 55 million companies, covering job titles, seniority, work history, company firmographics and contact details. Search returns thin records; enrichment returns the full profile.
Is it a CRM or a sequencer?
No, and it will not become one. LeadOcean is the data layer: an API and a set of agent tools. You keep your CRM, your sequencer and your warehouse — we fill them.
How do I connect Claude or ChatGPT?
Add https://api.leadocean.io/mcp as a remote MCP server in your app and sign in with your LeadOcean account. There is no key to paste, and you can disconnect an app at any time from your account. Step-by-step instructions for every client are in the docs.
What does "unlimited" actually mean?
Unlimited volume, not unlimited speed. On Pro there is no credit pack to buy, no per-record price, no overage invoice and no part of the database held back for a higher tier — you query all 700M+ profiles. Throughput is paced at 100 requests a second per key, and a very large month paces you down rather than cutting you off — you keep working, at one request a minute, until the reset. If a production workload needs more headroom, email support@leadocean.io and we raise it; the only thing we decline is scraping, crawling or unauthorised extraction, which the terms cover.
What counts as a record?
Every person or company we return counts one. A search page of 25 people counts 25; enriching one person counts 1, plus 1 more if you reveal their email address. Requests rejected for rate limits are never counted.
Is there really a free tier?
Yes. Sign up with your work email — free mailbox providers are not accepted — and you get an API key immediately, 1,000 records a month and the same API and MCP server as paid accounts. No credit card, and nothing expires after a trial period.
What are the rate limits?
Every plan allows 100 requests per second per key, paced evenly — free and paid alike. Go faster and the API answers 429 with a Retry-After header so your client can back off cleanly. Need more than that for a production workload? Email us.
Where does the data come from, and is it compliant?
We unify 20+ licensed and proprietary sources into a single schema, so you never reconcile vendors yourself. Every response names which dataset answered in the X-Source header, and unknown fields come back null rather than guessed. Read the privacy policy; anyone can ask to be removed at leadocean.io/legal/remove and the record is suppressed from every response immediately.
Can I cancel?
Any time, from the billing portal in your account. Your plan stays active until the end of the period you already paid for, then reverts to the free tier.
