Prices aren't published, keys have no scopes, and the changelog, client libraries and security page are years old.\n\n**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.\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### LeadMagic API + MCP\n\n1. Call `preview_cost` before bulk work. It's free\n2. Read `X-Credits-Remaining` after each call instead of polling the balance\n3. Treat 402 as out of credits and wait out Retry-After on 429\n4. Keep credit-free search under 13,333 calls a day per account\n5. Retry `unknown` validations later. They cost nothing\n\n## Questions\n\n### Which is better for AI agents, FullContact or LeadMagic API + MCP?\n\nLeadMagic API + MCP scores 60.2 (C) on agent readiness against FullContact's 51.8 (D), and leads in 5 of 7 scored categories. FullContact leads on reliability and agent ergonomics.\n\n### Do FullContact and LeadMagic API + MCP need an API key?\n\nFullContact needs an API key. LeadMagic API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call FullContact and LeadMagic API + MCP without installing anything?\n\nYes.
