People Data Labs
100World's largest people and company dataset with 3B+ person profiles and 70M+ companies — enrich, search, identify, and clean data via REST API with official SDKs.
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
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
