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)
- +Official Node (@fiberai/sdk) and Python (fiberai) SDKs
- +Three MCP servers (v3 OAuth, v2 API key, lite) and a first-party plugin
- +Agent-native docs: per-operation markdown, llms.txt and openapi.json
- –No free tier; entry plan $300/month
- –Trial requirements conflict between homepage and pricing page
- –No confirmed official status page or SLA
