# Get a Browser Use API Key

> Agent signup is off. Create an API key in Cloud, or use x402 without a human.

<Warning>
  Agent signup is off. The `/cloud/signup` endpoints return `403`.
</Warning>

Create an [API key](https://cloud.browser-use.com/settings?tab=api-keys\&new=1), then follow the [API V4 quick start](/cloud/agent/quickstart).

<Note>
  No human available? Use [x402](/cloud/guides/x402): pay per request from a wallet, without an account or API key.
