CREDENTIAL SECURITY

WHAT IS AN API KEY? DEMO & GUIDE

Think of it as a private VIP token for your browser engine. No passwords, instantly revocable, spend-capped to pennies, and 100% under your sovereign control.

A Scoped Cryptographic Signature

When you sign into a public website, you enter an email and password. But when Cue instructs an AI foundation model to compile your prompt, it uses an API key—a private hexadecimal token that authorizes raw token computation directly from your client sandbox.

Account Passwords
  • • Controls your entire billing & email account
  • • Can never be shared or scoped safely
  • • Never stored or requested by Cue
Cue BYOK API Keys
  • • Scoped strictly to prompt structuring calls
  • • Spend limits can be capped to 50 cents
  • • Stored 100% locally in chrome.storage.local

Zero Proxy Invariant: Requests travel directly from your browser to your selected AI provider. Cue operates zero intermediary proxy servers and never logs your prompt text or secrets.
