Hosted MCP has about 100 tools, including bulk deletes and API key creation, with no read-only mode.\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### Hunter API + MCP\n\n1. Treat 451 as final. The person opted out and retrying won't help\n2. Back off on 403 with a rate-limit message. 429 means the plan's credits are gone\n3. Send the key in `X-API-Key`, never as `?api_key=`\n4. Use `test-api-key` to check request shapes without spending credits\n5. Use the hosted MCP at mcp.hunter.io/mcp, not the deprecated local npm package\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, Hunter API + MCP or People Data Labs?\n\nPeople Data Labs scores 64.2 (B) on agent readiness against Hunter API + MCP's 56.5 (C), and leads in 4 of 7 scored categories. Hunter API + MCP leads on schema \u0026 documentation, payments \u0026 pricing and transparency \u0026 trust.\n\n### Do Hunter API + MCP and People Data Labs need an API key?\n\nHunter API + MCP takes an API key or an OAuth sign-in. People Data Labs needs an API key.\n\n### Can an agent call Hunter API + MCP and People Data Labs without installing anything?\n\nYes. Hunter API + MCP has a hosted endpoint at https://api.hunter.io/v2 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/hunter-vs-people-data-labs.json, and with the fewest tokens: https://www.anchorterminal.com/compare/hunter-vs-people-data-labs.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"hunter\", \"b\": \"people-data-labs\"}`.
