Ocean.io
Ocean.io is a B2B go-to-market data platform built around lookalike intelligence: give it a domain or a set of closed-won customers and it returns the most similar companies from a database of 67M company profiles and 250M+ employee records, each carrying 100+ signals assembled from the open web. Alongside the web app it ships a public REST API at api.ocean.io covering company and people search (filter, Boolean and lookalike), company and person enrichment, domain and LinkedIn-handle lookup, verified email and phone reveal, autocomplete for filter values, and a stateful segmentation service that clusters a customer list into scored segments and attributes new domains to the closest one. The API is documented with a public OpenAPI 3.1 document, meters every call from a single credit pool, delivers batch and reveal results by webhook callback, and is also exposed to agents through a first-party hosted MCP server at api.ocean.io/mcp.
Ocean.io publishes 8 API contracts indexed on the APIs.io network, including Autocomplete API, Enrich API, Lookup API, and 5 more. Tagged areas include Sales Intelligence, B2B, Data Enrichment, Lookalike, and Account Based Marketing.
The Ocean.io catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.
Ocean.io’s developer surface includes documentation, API reference, getting-started guide, pricing, authentication, and 25 more developer resources.
