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**RocketReach API.** The hosted MCP server has nine documented tools, OAuth 2.1 with dynamic client registration and machine-readable error codes, and searches cost no credits. Plan prices were not readable, the docs send API plan requests to email, the terms require a human account holder, and the `account` tool returns the account's API key to the model.\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### RocketReach API\n\n1. Search first with `person_search` or `company_search`, which cost no credits, then look up only the profile IDs needed\n2. Treat `status: \"pending\"` as normal. Poll `check_person_status` after at least 3 seconds, and polling is free\n3. Do not echo the `account` tool's output to users or logs. It includes the account's API key\n4. Send the key in the `Api-Key` header. The `api_key` query parameter is deprecated\n5. Bulk lookup takes 1 to 100 queries and needs a webhook. Results arrive at the webhook, signed in `X-RocketReach-Signature`\n6. Do not loop on `unknown` from `email_verify`, or on `lookup_failed` and `not_found`. The last two are terminal\n\n## Questions\n\n### Which is better for AI agents, Clearbit or RocketReach API?\n\nRocketReach API scores 51.2 (D) 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 RocketReach API need an API key?\n\nClearbit needs an API key. RocketReach API takes an API key or an OAuth sign-in.\n\n### Can an agent call Clearbit and RocketReach API without installing anything?\n\nNo hosted endpoint is listed for Clearbit. RocketReach API has a hosted endpoint at https://api.rocketreach.co/api/v2.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/clearbit-vs-rocketreach.json, and with the fewest tokens: https://www.anchorterminal.com/compare/clearbit-vs-rocketreach.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"clearbit\", \"b\": \"rocketreach\"}`.
