Strengths and weaknesses
- +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
- –Credit-based model can create unpredictable costs without active monitoring
- –No first-party SDKs, integration is raw REST (client libraries are community/third-party only)
- +Modern async API with webhooks or polling plus OpenAPI YAML/JSON specs
- +MCP server with 57 tools documented for Claude, Cursor, VS Code and ChatGPT
- +Published rate limits and simple credit rules (search 1 credit per 10 results; polling free)
- –Plan eligibility for the API is unclear and sources conflict
- –60 requests/min per endpoint, restrictive for bulk jobs
- –Pro and Enterprise pricing is sales-led
