Headless MCP use needs a master key that reaches every endpoint.\n\n**FullContact.** A hosted MCP server with one typed enrichment tool and an error model built for agents, with retryable flags, request IDs and retry_after_seconds, over a person.enrich API limited to 6,000 queries a minute. Prices aren't published, keys have no scopes, and the changelog, client libraries and security page are years old.\n\n## Before you call either\n\n### Apollo API + MCP\n\n1. Search people first at 0 credits, then enrich only the people you'll contact\n2. Branch on `error_details.code` and wait `retry_after_seconds` from the suggestions after a 429\n3. Limits are per team, so read the `x-minute-usage` and remaining headers before a bulk run\n4. Use a scoped key with only the endpoints the job needs. A master key reaches everything\n5. Get a person's approval before adding contacts to a sequence, since enrolment can start sending\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## Questions\n\n### Which is better for AI agents, Apollo API + MCP or FullContact?\n\nApollo API + MCP scores 63.3 (B) on agent readiness against FullContact's 51.8 (D), and leads in 6 of 7 scored categories. FullContact leads on agent ergonomics.\n\n### Do Apollo API + MCP and FullContact need an API key?\n\nApollo API + MCP takes an API key or an OAuth sign-in. FullContact needs an API key.\n\n### Can an agent call Apollo API + MCP and FullContact without installing anything?\n\nYes. Apollo API + MCP has a hosted endpoint at https://api.apollo.io/api/v1 and FullContact at https://api.fullcontact.com/v3.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/apollo-vs-fullcontact.json, and with the fewest tokens: https://www.anchorterminal.com/compare/apollo-vs-fullcontact.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"apollo\", \"b\": \"fullcontact\"}`.
