## Before you call it

1. Always send `x-api-version: 2025-11-01`. Unpinned calls get the latest version
2. Call `/account/endpoints` first to see what your plan enables and what each field costs
3. Ask only for the premium field groups you need, since each one bills
4. Poll `GET /batch/{id}` before submitting more batch jobs. Active jobs count against a cap of 5 to 30
5. Read the `crustdata://catalog` resource before calling MCP tools
