## Verdicts

**Crustdata API + MCP.** Per-field credit prices, readable per account from `/account/endpoints`, and `X-Credits-Used` on every response. No status page and no SLA.

## 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

### Prospeo API + MCP

1. Call `search_suggestions` before using location, technology or industry filters, or the search returns nothing
2. Pass `person_id` values from search into `bulk_enrich_person`, 25 at a time
3. Branch on the body `error_code`, not the HTTP status, which is 400 for most failures
4. Set `enrich_mobile` only when needed. A mobile costs 10 credits against 1 for an email
5. Use Enrich Person. The old Email Finder endpoint was removed in March 2026
