Clearbit

This is a Membrane-powered integration for Clearbit's data enrichment APIs, letting you look up people and companies from emails, domains, or IP addresses. Sales and marketing teams use Clearbit to identify prospects and personalize outreach, and this skill wraps their APIs with automated auth handling so you skip the credential plumbing. You can enrich person data by email, reveal companies by IP, search for people at specific domains, or combine lookups in a single call. The Membrane CLI approach means you authenticate once and the platform handles token refresh behind the scenes. When pre-built actions don't cover your case, proxy requests go straight through to Clearbit's API with auth injected automatically.

Working with Clearbit

This skill uses the Membrane CLI to interact with Clearbit. Membrane handles authentication and credentials refresh automatically — so you can focus on the integration logic rather than auth plumbing.

Install the CLI

Install the Membrane CLI so you can run membrane from the terminal:

npm install -g @membranehq/cli@latest

Authentication

membrane login --tenant --clientName=<agentType>

This will either open a browser for authentication or print an authorization URL to the console, depending on whether interactive mode is available.

Headless environments: The command will print an authorization URL. Ask the user to open it in a browser. When they see a code after completing login, finish with:
