What it looks like

{
  "code": "UNSUPPORTED_ROUTE",
  "detail": "A sentence describing this particular failure.",
  "field_errors": [],
  "instance": "/api/public/v1/...",
  "next_action": "This journey is outside the served area. Do not retry unchanged.",
  "request_id": "req_9f2c1b7ae4d84c6f9b2e10a3",
  "retryable": false,
  "status": 422,
  "title": "Route not served",
  "type": "https://swisstouristy.com/developers/errors/unsupported_route"
}

code is the stable contract. detail is prose for a human reading a log and may be reworded at any time — do not parse it, and do not branch on status alone, since several codes share one.
