# Clearbit (slim)

> Clearbit is a B2B data provider for company, contact and IP intelligence, acquired by HubSpot. It still runs enrichment, reveal and prospecting APIs for existing customers, and HubSpot's Breeze Intelligence carries its data for new buyers.

Assessment: There is no public API or MCP server an outside agent can call today. 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.

## Before you call it

1. 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
2. Replace logo.clearbit.com links, which stopped working after 8 December 2025
