Billing and API keys
Create API keys in Organization → API Keys. A key can limit access to named models and namespaces. Copy its token when it is created, then configure clients to send it as Authorization: Bearer <token>.
The default key is convenient for a first integration. Create distinct scoped keys for separate applications or environments, then revoke or rotate a key when its holder changes. Treat every token as a secret.
Billing tracks runtime usage. Keep the workspace balance funded before a production launch. The runtime rejects new requests when the workspace balance is insufficient, rather than silently sending requests upstream.
