No status page and no SLA.\n\n**Lusha API + MCP.** API key on every plan, including Free with 40 credits a month. At least 1 credit per request even when nothing matches.\n\n## Before you call either\n\n### Crustdata API + MCP\n\n1. Always send `x-api-version: 2025-11-01`. Unpinned calls get the latest version\n2. Call `/account/endpoints` first to see what your plan enables and what each field costs\n3. Ask only for the premium field groups you need, since each one bills\n4. Poll `GET /batch/{id}` before submitting more batch jobs. Active jobs count against a cap of 5 to 30\n5. Read the `crustdata://catalog` resource before calling MCP tools\n\n### Lusha API + MCP\n\n1. Batch up to 25 contacts a request. A single bulk request costs 1 credit, not 1 per contact\n2. Ask for phones only when needed. A phone is 5 credits against 1 for an email\n3. Use the Buying Group endpoint. Decision Makers was retired on 2026-09-04\n4. Use `/v3/lookalike/contacts` for contact lookalikes\n5. Back off exponentially on 429. Free keys stop at 100 requests a day\n\n## Other comparisons with Crustdata API + MCP or Lusha API + MCP\n\n- [Apollo API + MCP vs Crustdata API + MCP](https://www.anchorterminal.com/compare/apollo-vs-crustdata.md)\n- [Apollo API + MCP vs Lusha API + MCP](https://www.anchorterminal.com/compare/apollo-vs-lusha.md)\n- [Coresignal API + MCP vs Crustdata API + MCP](https://www.anchorterminal.com/compare/coresignal-vs-crustdata.md)\n- [Coresignal API + MCP vs Lusha API + MCP](https://www.anchorterminal.com/compare/coresignal-vs-lusha.md)\n- [Crustdata API + MCP vs Enrich Layer API + MCP](https://www.anchorterminal.com/compare/crustdata-vs-enrich-layer.md)\n- [Crustdata API + MCP vs FullEnrich API + MCP](https://www.anchorterminal.com/compare/crustdata-vs-fullenrich.md)\n- [Crustdata API + MCP vs Hunter API + MCP](https://www.anchorterminal.com/compare/crustdata-vs-hunter.md)\n- [Crustdata API + MCP vs LeadMagic API + MCP](https://www.anchorterminal.com/compare/crustdata-vs-leadmagic.md)\n- [Crustdata API + MCP vs Prospeo API + MCP](https://www.anchorterminal.com/compare/crustdata-vs-prospeo.md)\n- [Enrich Layer API + MCP vs Lusha API + MCP](https://www.anchorterminal.com/compare/enrich-layer-vs-lusha.md)\n- [FullEnrich API + MCP vs Lusha API + MCP](https://www.anchorterminal.com/compare/fullenrich-vs-lusha.md)\n- [LeadMagic API + MCP vs Lusha API + MCP](https://www.anchorterminal.com/compare/leadmagic-vs-lusha.md)\n- [Lusha API + MCP vs Prospeo API + MCP](https://www.anchorterminal.com/compare/lusha-vs-prospeo.md)\n- [Crustdata API + MCP vs Dropcontact API + MCP](https://www.anchorterminal.com/compare/crustdata-vs-dropcontact.md)\n- [Dropcontact API + MCP vs Lusha API + MCP](https://www.anchorterminal.com/compare/dropcontact-vs-lusha.md)\n- [Hunter API + MCP vs Lusha API + MCP](https://www.anchorterminal.com/compare/hunter-vs-lusha.md)\n",
