	People Data Labs	Sixtyfour
Pros	+ 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	+ Flexible struct parameter lets agents define exactly which fields to return in natural language — no rigid schema to map + Async endpoints with polling prevent timeout issues on long-running enrichment (P95 ~5 min), critical for agent orchestration + Significantly higher enrichment coverage than Apollo/BuiltWith — surfaces data on even tiny businesses with a few employees
Cons	- 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	- No public pricing or free tier — agents can't self-provision, requires sales contact to get started - Sync enrichment calls can take up to 15 minutes; agents must use async+polling pattern or risk HTTP timeouts
