- +Quickstart, API playgrounds, rate-limit reference and llms.txt/llms-full.txt exports in the docs
- +Official MCP server for Claude, Cursor and other MCP clients
- –No official language SDKs, OpenAPI spec page or Postman collection found in the docs index
- –Free access is a 7-day trial only, not a recurring free tier
- –Company data refreshes roughly monthly per third-party reviews; no direct-dial phone numbers
- +Genuine real-time / live web indexing, returns data for untracked companies within minutes rather than serving stale batch data
- +Watcher API + webhooks push change signals (job changes, funding, promotions) the moment they're detected
- +Clean, fast, well-documented REST API that reviewers say makes integration 'almost effortless'
- –Paid plan pricing is opaque, no named tiers or list prices published; heavier endpoints gated behind enterprise/demo requests
