Manage Your API Keys - Yellow Guide

Every pairing mints a new API key for that client, scoped to exactly the permissions you chose. You can see and manage all of them from API Key Management in your account settings.

API Key Management screen

What each column shows

Column	What it tells you
API Key	A truncated identifier. The full secret is never shown here.
AI / Client	Which assistant the key belongs to, and its access level (for example Read & trade).
State	An Active toggle. Switching it off instantly freezes that key.
Created / Expire	When the key was minted and when it expires. Keys are valid for one year.
Last Used	The most recent call the key made — useful for spotting a client that’s gone quiet, or one that’s calling more than expected.

Freezing a key

Toggling State off is immediate and reversible, even if your AI is mid-session. It’s the fastest way to cut off one AI client without touching any others connected to your account.

Adding another key

Click Create to mint an additional key manually, or go back through the agent onboarding flow to pair a brand-new client.

A new key is minted for each AI you connect. Revoking one stops only that agent — the others keep working, and your account and balance are unaffected.
