	Apollo	People Data Labs
Pros	+ Massive dataset (210M+ contacts, 30M+ companies) with structured JSON responses — agents get rich firmographic and demographic data in a single call + People Search endpoint does not consume credits, so agents can search and filter freely before committing credits to enrichment + Simple API Key auth via x-api-key header and straightforward REST endpoints make integration trivial for any agent framework	+ 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	- Credit-based pricing adds complexity for agents — different actions cost different credit amounts (1 for email, 5 for mobile), requiring agents to track budget - No official OpenAPI spec, so agents can't auto-discover endpoints or generate typed clients without manual setup	- 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
