	Fiber AI	People Data Labs
Pros	+ First-class agent support — official MCP server, Python/TypeScript SDKs, and dedicated agentic search endpoints that convert natural language to structured filters + Comprehensive OpenAPI 3.1 spec (90+ endpoints) makes tool-use integration trivial for LLM function calling + Unique endpoints competitors lack: reverse email-to-person lookup, real-time LinkedIn live fetch, kitchen-sink enrichment, and GitHub-to-LinkedIn resolution	+ Massive dataset — 3B+ person profiles and 70M+ companies with broad coverage across enrichment, search, identify, and IP endpoints + Official OpenAPI spec on GitHub and SDKs for Python, JS, Ruby, and Go with clean REST design and predictable JSON responses + Generous free tier with no credit card required, and Autocomplete/Cleaner APIs are completely free with only rate limits
Cons	- No permanent free tier — only a 7-day trial, then minimum $300/mo - Auth is non-standard (apiKey in request body for POST, query param for GET) rather than a standard Authorization header, requiring custom handling in generic API clients	- Free tier is very limited at 100 lookups/month — Pro starts at $98/mo for only 350 person credits, making serious usage expensive - Search API rate limit is tight at 10 req/min even on paid plans, which can bottleneck agent workflows doing bulk lookups
