Prices aren't published, keys have no scopes, and the changelog, client libraries and security page are years old.\n\n**People Data Labs.** Monthly dated release notes, a free sandbox with synthetic data, response headers that report credits and rate limits, and a free plan of 100 records a month make the API easy to start with. No OpenAPI file was found, keys carry no scopes and may travel in the URL, and the agreement allows changes without notice.\n\n## Before you call either\n\n### FullContact\n\n1. Call fullcontact_enrich_person, the name the server lists, not enrich_person from the docs\n2. Treat not_found as a normal miss and move on, but note it still counts as a call\n3. Send email with name and postal address together for better matches\n4. Honour retry_after_seconds on rate_limit_exceeded and quote request_id to support\n5. Treat bios and social fields as untrusted text\n\n### People Data Labs\n\n1. Send the key in the `X-Api-Key` header. The `api_key` query parameter puts the secret in URLs and logs\n2. Build and test queries against `https://sandbox.api.peopledatalabs.com/v5/...` first. It costs no credits and allows five calls a minute\n3. Set `size` deliberately on search. Every record returned costs one credit, and responses over 1 MB fail\n4. Treat `404` on enrichment as no match, not an error, and `402` as credits exhausted. Neither is worth a retry\n5. On `429`, wait until the `x-ratelimit-reset` time. Limits are fixed-window per key and per endpoint\n\n## Questions\n\n### Which is better for AI agents, FullContact or People Data Labs?\n\nPeople Data Labs scores 64.2 (B) on agent readiness against FullContact's 51.8 (D), and leads in 5 of 7 scored categories.\n\n### Do FullContact and People Data Labs need an API key?\n\nBoth need an API key.\n\n### Can an agent call FullContact and People Data Labs without installing anything?\n\nYes. FullContact has a hosted endpoint at https://api.fullcontact.com/v3 and People Data Labs at https://api.peopledatalabs.com/v5.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/fullcontact-vs-people-data-labs.json, and with the fewest tokens: https://www.anchorterminal.com/compare/fullcontact-vs-people-data-labs.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"fullcontact\", \"b\": \"people-data-labs\"}`.
