## Request body

- object

## Response `200`

Created session

  - `data` object: Short-lived chat session projection with quota and decrypted messages.

## Other responses

- `400`: Bad request. Query parameters are validated strictly: a parameter this document does not list is rejected, and `details[].keys` names it. A misspelled filter used to be dropped silently, which answered a question nobody asked with a plausible list of products.
- `401`: Unauthorized
