Claude API / Documentation

Bring-your-own-key concepts

Keep provider credentials under your control. BYOK is a documentation concept here, not an implemented key vault.

Keep secrets on the server

Use environment variables or a secret manager and limit key permissions. Never put provider keys in client-side code, screenshots, repositories, or query strings.

No keys required for the preview

This site does not ask you to upload a provider key. Sign in with Google only if you want to explore the account and test subscription flow.
