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

LeadMagic API + MCP

  1. Call preview_cost before bulk work. It's free
  2. Read X-Credits-Remaining after each call instead of polling the balance
  3. Treat 402 as out of credits and wait out Retry-After on 429
  4. Keep credit-free search under 13,333 calls a day per account
  5. Retry unknown validations later. They cost nothing
