Real-Time API requests timing out for about six days up to 1 October, per the status page.\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### Coresignal API + MCP\n\n1. Search for IDs first (free), then collect only the records you need\n2. Use base records at 10 credits when you don't need the 20-credit multi-source fields\n3. Use MCP v2 at /mcp/v2. The older /mcp endpoint will be deprecated\n4. Treat a 402 as out of credits, not a transient error\n5. Expect no work emails for EEA and UK people from the MCP email tool\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, Coresignal API + MCP or People Data Labs?\n\nPeople Data Labs scores 64.2 (B) on agent readiness against Coresignal API + MCP's 62.9 (B), and leads in 3 of 7 scored categories. Coresignal API + MCP leads on schema \u0026 documentation and security \u0026 auth.\n\n### Do Coresignal API + MCP and People Data Labs need an API key?\n\nCoresignal API + MCP takes an API key or an OAuth sign-in. People Data Labs needs an API key.\n\n### Can an agent call Coresignal API + MCP and People Data Labs without installing anything?\n\nYes. Coresignal API + MCP has a hosted endpoint at https://api.coresignal.com/cdapi 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/coresignal-vs-people-data-labs.json, and with the fewest tokens: https://www.anchorterminal.com/compare/coresignal-vs-people-data-labs.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"coresignal\", \"b\": \"people-data-labs\"}`.
