Coresignal Crustdata
Pros
  • + Massive scale — 3B+ records across companies, employees, and jobs with regular freshness updates
  • + Official MCP server for direct LLM/agent integration with multi-source company, employee, and jobs APIs
  • + Clean REST API with simple API key auth, Elasticsearch DSL support for complex queries, and bulk collect endpoints
  • + Extensive real-time B2B data — 250+ company firmographics and 90+ people datapoints with near-instant freshness updates
  • + Watcher API enables event-driven agent workflows via webhooks for job switches, funding rounds, and other company/people changes
  • + Simple REST API with token auth and JSON responses makes integration straightforward for LLM agents
Cons
  • - No free ongoing tier — free trial is 14 days only, paid plans start at $49/mo with limited credits
  • - Raw data may require preprocessing (duplicates, HTML artifacts, inconsistent formatting from web-scraped sources)
  • - No public OpenAPI spec — agents must rely on manually coded endpoint definitions
  • - Credit-based pricing can be opaque; free tier is limited and paid plans require contacting sales for enterprise volumes
