Verdicts

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.

Prospeo API + MCP

MCP tool descriptions say when to use each tool, its credit cost and the next call. No status page, SLA or changelog.

Before you call either

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

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
