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### ZoomInfo API + MCP\n\n1. Call Lookup first and pass the returned IDs to Search. Unknown industry, metro or topic strings are rejected with a 422\n2. Search before Enrich. Search is free, and each newly enriched record costs one data credit\n3. Request only the scopes the task needs in the `scope` parameter of the token call. Omitting it grants every scope configured on the app\n4. On 429 read `X-RateLimit-Rejected-Bucket` and wait for `Retry-After`. An exhausted hourly window can mean a wait of several hundred seconds\n5. Turn off model training in the AI client before connecting the MCP server. ZoomInfo prohibits MCP data being used for training\n\n## Questions\n\n### Which is better for AI agents, Crustdata API + MCP or ZoomInfo API + MCP?\n\nZoomInfo API + MCP scores 72.2 (BB) on agent readiness against Crustdata API + MCP's 53.4 (D), and leads in 5 of 7 scored categories. Crustdata API + MCP leads on schema \u0026 documentation.\n\n### Do Crustdata API + MCP and ZoomInfo API + MCP need an API key?\n\nCrustdata API + MCP takes an API key or an OAuth sign-in. ZoomInfo API + MCP uses an OAuth sign-in.\n\n### Can an agent call Crustdata API + MCP and ZoomInfo API + MCP without installing anything?\n\nYes.
