What A Key Can Control

Each key can include:

  • a name
  • one or more permissions
  • allowed origins
  • a per-minute rate limit
  • active or inactive status

Supported permissions are:

PermissionUse it for
chatChat and streaming endpoints
retrieveRetrieval-only queries and some voice tool flows
ingestProgrammatic content ingestion

Important Behavior

  • raw keys are only shown once when created
  • inactive keys stay listed but cannot authenticate requests
  • the system may create a bootstrap retrieve key for voice tooling when needed

Good Key Hygiene

  • create separate keys for separate use cases
  • limit permissions to the minimum required
  • set allowed origins for browser-based use where possible
  • rotate keys when ownership changes
  • delete old keys instead of leaving them dormant forever

Typical Examples

Widget or frontend integration

Use a key with only the permissions the integration actually needs, plus allowed origins.

Use a retrieve-only key.

Content ingestion workflow

Use an ingest key that is not shared with chat clients.
