### 401 — Missing, malformed, expired or revoked bearer token. The `WWW-Authenticate` header carries the RFC 6750 challenge.

`application/json` — `ErrorEnvelope`

```json
{
  "error": {
    "code": "unauthorized",
    "message": "A valid bearer token is required.",
    "details": [],
    "request_id": "7d4c2f48-9a1b-4c3d-8e2f-1a2b3c4d5e6f",
    "doc_url": "https://cascades.crscreditapi.com/docs/api/errors/unauthorized"
  }
}
```

### 403 — Token does not hold the required scope. `details` lists the scope(s) that were checked.

`application/json` — `ErrorEnvelope`

```json
{
  "error": {
    "code": "insufficient_scope",
    "message": "This token does not have the required scope.",
    "details": [
      {
        "field": "scope",
        "message": "executions:write"
      }
    ],
    "request_id": "7d4c2f48-9a1b-4c3d-8e2f-1a2b3c4d5e6f",

```

### 429 — Rate limit exceeded (60 req/min per IP on `/api/v1`, 600 req/hour
per token prefix, or 300 req/5 min per IP globally). The body is the
standard error envelope and `Retry-After` gives the seconds until
the window resets.


`application/json` — `ErrorEnvelope`

```json
{
  "error": {
    "code": "rate_limited",
    "message": "Rate limit exceeded. Retry later.",
    "details": [],
