A lead source here is a list you build from filters, not a file we hand you. LeadOcean holds 693M people and 63M companies, and each page below shows one way to cut that into a list: by title, department, location, industry, technology, phone or email status. The pages give the filter names, the exact allowed values and a count you can check yourself.

Every page maps to the same two paths. Over REST, POST /v1/people/search and POST /v1/companies/search take the filters as a flat JSON body, and POST /v1/exports pulls the full list. Over MCP, leadocean_count_leads sizes a list for free, leadocean_search_leads and leadocean_search_companies return rows, and leadocean_export_leads writes the CSV. For the term, see lead scrape. For what to do with a list afterwards, see lead routing.

Free count, dated

One live count, so you know what sizing looks like. leadocean_count_leads returned 115,336 on 2026-10-01 for jobLevel VP, jobFunction Sales & Business Development, country US. That is people with a verified, catch_all_valid or catch_all email, the tool's default filter. The call spent no records.

People

Start here when you know the buyer. These pages filter on who the person is and where they work.

Contact status

These pages filter on whether you can reach the person, before you spend a record on the details.

Companies

Start here when you build from the account side.

Funding and new companies

Bulk output

  • Bulk CSV Export: up to 50,000 rows per export, from the API or the Exports page in the app.

How to choose

  • You know the buyer. Use Find Decision Makers. jobLevel and jobFunction get you to the right seat faster than a title string.
  • You know the account type. Start on the company side with industry, headcount or technology, then pull the people at those companies.
  • You need to call or email. Use the contact status pages first. They keep only people we hold a number or a sendable email for.
  • You want a list now, not code. Use Bulk CSV Export. The Exports page in the app has a filter builder, a column picker and the record price before you start.
  • You are comparing build against buy. Read best open source lead generation tools first, then size the same list here for free.

FAQ

Does sizing a list cost anything?

No. leadocean_count_leads, list_filters and list_enum_values are free. A search costs 1 record per person or company returned, and an export row costs 1 record. Free gives you 1,000 records, one-off. Pro is $499 a month. See pricing.

Which filter values are allowed?

Enum filters take exact strings, such as jobLevel VP or jobFunction Sales & Business Development. Call list_enum_values for the full set. list_filters returns all 50 people filters and 34 company filters.

Can a count be wrong?

Read the label on it. The MCP count defaults to people with a verified, catch_all_valid or catch_all email. On the REST API, meta.total stops at 100,000, so a bigger list reads as a floor there. A few filters, including fundingType and minRevenue, cannot be counted, and the page that uses them says so.
