B2B lookalike search and enrichment API with 230M+ contacts and 35M+ company profiles — company/people enrichment, lookalike search, and email/phone reveal via REST endpoints.

OpenAPI SpecAPI KeySubscriptionJSONBot Blocking: Nonecompany-searchpeople-searchcompany-enrichmentpeople-enrichmentlookalike-searchemail-finderphone-finderb2b-datalead-generation

Pros

  • + Lookalike search endpoint lets agents find companies similar to a target — unique capability for ICP-driven prospecting that most enrichment APIs lack
  • + Simple API key auth via x-api-token header or apiToken query param, JSON in/out, clean REST design at api.ocean.io/v2/* — trivial to integrate in any agent framework
  • + Swagger/OpenAPI spec available at docs.oceanio.com, enabling auto-generated typed clients and agent tool discovery

Cons

  • - No free tier — 14-day trial requires credit card and annual contracts on paid plans, making it expensive to experiment with in agent workflows
  • - Credit-based pricing for email/phone reveals adds budget-tracking complexity for autonomous agents that need to manage costs per action
