# Manage Your API Keys
> Review, freeze, and revoke the keys minted for each connected AI client.
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.
## 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](/mcp/getting-started) 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.
