Note: Clearbit was acquired by HubSpot in 2023 and is now sold as HubSpot Breeze Intelligence. The legacy clearbit.com API endpoints remain functional for existing customers as of 2025 but new sign-ups go through HubSpot. Set your CLEARBIT_API_KEY exactly as Clearbit issues it.
Setup:
- Sign in to https://dashboard.clearbit.com → API Keys (or for HubSpot Breeze: HubSpot Settings → Integrations → Breeze Intelligence → API).
- Copy the secret API key (prefixed with
sk_). - Set
CLEARBIT_API_KEY.
Authentication: HTTP Basic with username=API_KEY, password=empty (Stripe-style). The adapter uses BASIC_AUTH.
