No status page, SLA or changelog.\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### Prospeo API + MCP\n\n1. Call `search_suggestions` before using location, technology or industry filters, or the search returns nothing\n2. Pass `person_id` values from search into `bulk_enrich_person`, 25 at a time\n3. Branch on the body `error_code`, not the HTTP status, which is 400 for most failures\n4. Set `enrich_mobile` only when needed. A mobile costs 10 credits against 1 for an email\n5. Use Enrich Person. The old Email Finder endpoint was removed in March 2026\n\n## Other comparisons with Coresignal API + MCP or Prospeo API + MCP\n\n- [Apollo API + MCP vs Coresignal API + MCP](https://www.anchorterminal.com/compare/apollo-vs-coresignal.md)\n- [Apollo API + MCP vs Prospeo API + MCP](https://www.anchorterminal.com/compare/apollo-vs-prospeo.md)\n- [Coresignal API + MCP vs Crustdata API + MCP](https://www.anchorterminal.com/compare/coresignal-vs-crustdata.md)\n- [Coresignal API + MCP vs Enrich Layer API + MCP](https://www.anchorterminal.com/compare/coresignal-vs-enrich-layer.md)\n- [Coresignal API + MCP vs FullEnrich API + MCP](https://www.anchorterminal.com/compare/coresignal-vs-fullenrich.md)\n- [Coresignal API + MCP vs Hunter API + MCP](https://www.anchorterminal.com/compare/coresignal-vs-hunter.md)\n- [Coresignal API + MCP vs LeadMagic API + MCP](https://www.anchorterminal.com/compare/coresignal-vs-leadmagic.md)\n- [Coresignal API + MCP vs Lusha API + MCP](https://www.anchorterminal.com/compare/coresignal-vs-lusha.md)\n- [Crustdata API + MCP vs Prospeo API + MCP](https://www.anchorterminal.com/compare/crustdata-vs-prospeo.md)\n- [Enrich Layer API + MCP vs Prospeo API + MCP](https://www.anchorterminal.com/compare/enrich-layer-vs-prospeo.md)\n- [FullEnrich API + MCP vs Prospeo API + MCP](https://www.anchorterminal.com/compare/fullenrich-vs-prospeo.md)\n- [LeadMagic API + MCP vs Prospeo API + MCP](https://www.anchorterminal.com/compare/leadmagic-vs-prospeo.md)\n- [Lusha API + MCP vs Prospeo API + MCP](https://www.anchorterminal.com/compare/lusha-vs-prospeo.md)\n- [Coresignal API + MCP vs Dropcontact API + MCP](https://www.anchorterminal.com/compare/coresignal-vs-dropcontact.md)\n- [Dropcontact API + MCP vs Prospeo API + MCP](https://www.anchorterminal.com/compare/dropcontact-vs-prospeo.md)\n- [Hunter API + MCP vs Prospeo API + MCP](https://www.anchorterminal.com/compare/hunter-vs-prospeo.md)\n",
