4. Create an API key

Inference calls authenticate with a Bearer API key (prefixed pzero_), not your session cookie. Keys are how agents and integrations reach the API.

Steps

1. Open API keys in your account.
2. Click Create key and give it a name.
3. Copy the key: it is shown only once. Store it securely.
4. Use it as Authorization: Bearer pzero_… on inference requests.

Managing keys

• List your active keys with their name, prefix, created date, and last used.
• Revoke a key at any time; revocation is immediate and does not affect your other keys.

Two credentials, not interchangeable

The session cookie authenticates account, funding, and supply actions. The Bearer key authenticates inference. Sending a session cookie to the inference endpoint is rejected, and vice versa.
