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

Enrich Layer API + MCP

  1. Top up once before testing. Trial keys run at 2 requests a minute
  2. Set the person profile timeout to at least 100 seconds
  3. Ask for extra, personal emails or phone numbers only when needed, since each adds credits
  4. Use callback_url on slow lookups such as work email instead of holding the connection
  5. Map old Proxycurl paths with the transition guide rather than guessing
