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**Enrich Layer API + MCP.** Pay-as-you-go credits from $10, non-expiring unless idle for 18 months. Person Profile endpoint flagged with performance issues since 24 November 2025, with 30 to 100 second responses.\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### Enrich Layer API + MCP\n\n1. Top up once before testing. Trial keys run at 2 requests a minute\n2. Set the person profile timeout to at least 100 seconds\n3. Ask for `extra`, personal emails or phone numbers only when needed, since each adds credits\n4. Use `callback_url` on slow lookups such as work email instead of holding the connection\n5. Map old Proxycurl paths with the transition guide rather than guessing\n\n## Questions\n\n### Which is better for AI agents, Clearbit or Enrich Layer API + MCP?\n\nEnrich Layer API + MCP scores 55.8 (C) on agent readiness against Clearbit's 13.5 (F), and leads in 6 of 7 scored categories. Clearbit leads on transparency \u0026 trust.\n\n### Do Clearbit and Enrich Layer API + MCP need an API key?\n\nBoth need an API key.\n\n### Can an agent call Clearbit and Enrich Layer API + MCP without installing anything?\n\nNo hosted endpoint is listed for Clearbit.
