Verdicts

Apollo API + MCP

People search costs 0 credits, up to 100 records a page and 50,000 a query. Headless MCP use needs a master key that reaches every endpoint.

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

Apollo API + MCP

  1. Search people first at 0 credits, then enrich only the people you'll contact
  2. Branch on error_details.code and wait retry_after_seconds from the suggestions after a 429
  3. Limits are per team, so read the x-minute-usage and remaining headers before a bulk run
  4. Use a scoped key with only the endpoints the job needs. A master key reaches everything
  5. Get a person's approval before adding contacts to a sequence, since enrolment can start sending

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
