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**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### 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### 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, Clearbit or LeadMagic API + MCP?\n\nLeadMagic API + MCP scores 60.2 (C) on agent readiness against Clearbit's 13.5 (F), and leads in 6 of 7 scored categories.\n\n### Do Clearbit and LeadMagic API + MCP need an API key?\n\nClearbit needs an API key. LeadMagic API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call Clearbit and LeadMagic API + MCP without installing anything?\n\nNo hosted endpoint is listed for Clearbit.
