Frequently asked questions

Everything you need to know about the product.

How does LeadBase work with my AI?

LeadBase is an MCP server. You add one URL to Claude, ChatGPT, Cursor, or any MCP client, sign in, and your agent can search, count, enrich, and export contacts in plain English.

Is it really unlimited?

Yes. The Unlimited plan has a flat monthly price with no per-contact credits and no seat fees. Our fair usage policy only stops bulk resale of the database.

How fresh is the data?

Every contact carries the date its email was last verified. Emails are checked by MillionVerifier and the database is refreshed monthly.

Do I need an API key?

Most clients connect by signing in. You only need an API key for the REST API or for clients such as Cline. Keys live in your dashboard.
