## Before you call either

### Crustdata API + MCP

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

### Dropcontact API + MCP

1. Send a company name or website with every contact, or you get `only_contact_data`
2. Send only documented fields. New accounts get a 400 for unknown ones
3. Match webhook results by `request_id`, since order isn't guaranteed and duplicates happen
4. Poll no faster than every 30 seconds, as the not-ready response asks
5. Post an empty contact to read the credit balance at no cost
