# Access Token

`POST /auth/access-token`

Exchange credentials for a JWT access token.

Accepts either:
- `client_id` + `secret` (classic API token flow)
- `project_key`: a Streamkap Project Key credential file (raw JSON or base64-encoded)

For `project_key` input, the API credentials are extracted from the bundle and used
to issue the JWT. Kafka-only Project Keys (no API credentials) cannot be exchanged
for a JWT.
