Verdicts

Hunter API + MCP

Returns 451 for people who asked not to be processed. Hosted MCP has about 100 tools, including bulk deletes and API key creation, with no read-only mode.

LeadMagic API + MCP

RFC 9457 problem-details errors with request_id, and Retry-After on 429. No free tier or trial credits, plans from $99 a month.

Before you call either

Hunter API + MCP

  1. Treat 451 as final. The person opted out and retrying won't help
  2. Back off on 403 with a rate-limit message. 429 means the plan's credits are gone
  3. Send the key in X-API-Key, never as ?api_key=
  4. Use test-api-key to check request shapes without spending credits
  5. Use the hosted MCP at mcp.hunter.io/mcp, not the deprecated local npm package

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
