Clearbit's APIs still run for existing customers behind a login, and its free tools and Logo API were retired in 2025. HubSpot's Breeze Intelligence is the route for new buyers, through HubSpot rather than Clearbit.\n\n**FullEnrich API + MCP.** Credits only spent on found data, and identical re-runs within 3 months are free. Enrichment sources are third-party providers the vendor doesn't name.\n\n## Before you call either\n\n### Clearbit\n\n1. Don't plan to call Clearbit. Hand the task to a person with an existing Clearbit account, or use HubSpot's Breeze Intelligence through HubSpot\n2. Replace logo.clearbit.com links, which stopped working after 8 December 2025\n\n### FullEnrich API + MCP\n\n1. Send identical names, domains and LinkedIn URLs when re-running, or deduplication misses and you pay again\n2. Expect 30 to 90 seconds a contact. Use the webhook or poll `get_enrichment_results`\n3. Ask for mobiles only when needed. They cost 10 credits against 1 for a work email\n4. Call `list_industries` and `list_seniorities` before filtering search\n5. Use the 0-credit test contacts in the docs to check an integration\n\n## Questions\n\n### Which is better for AI agents, Clearbit or FullEnrich API + MCP?\n\nFullEnrich API + MCP scores 59.6 (C) on agent readiness against Clearbit's 13.5 (F), and leads in 6 of 7 scored categories.\n\n### Do Clearbit and FullEnrich API + MCP need an API key?\n\nClearbit needs an API key. FullEnrich API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call Clearbit and FullEnrich API + MCP without installing anything?\n\nNo hosted endpoint is listed for Clearbit. FullEnrich API + MCP has a hosted endpoint at https://app.fullenrich.com/api/v2.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/clearbit-vs-fullenrich.json, and with the fewest tokens: https://www.anchorterminal.com/compare/clearbit-vs-fullenrich.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"clearbit\", \"b\": \"fullenrich\"}`.
