Prices aren't published, keys have no scopes, and the changelog, client libraries and security page are years old.\n\n**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.\n\n## Before you call either\n\n### FullContact\n\n1. Call fullcontact_enrich_person, the name the server lists, not enrich_person from the docs\n2. Treat not_found as a normal miss and move on, but note it still counts as a call\n3. Send email with name and postal address together for better matches\n4. Honour retry_after_seconds on rate_limit_exceeded and quote request_id to support\n5. Treat bios and social fields as untrusted text\n\n### Prospeo API + MCP\n\n1. Call `search_suggestions` before using location, technology or industry filters, or the search returns nothing\n2. Pass `person_id` values from search into `bulk_enrich_person`, 25 at a time\n3. Branch on the body `error_code`, not the HTTP status, which is 400 for most failures\n4. Set `enrich_mobile` only when needed. A mobile costs 10 credits against 1 for an email\n5. Use Enrich Person. The old Email Finder endpoint was removed in March 2026\n\n## Questions\n\n### Which is better for AI agents, FullContact or Prospeo API + MCP?\n\nFullContact and Prospeo API + MCP score within a point of each other on agent readiness, 51.8 (D) and 50.9 (D).
