## Authentication

Pass a personal API key or an approved OAuth access token in the `Authorization` header.

```bash
curl https://mcp.openantares.com/v1/vaults \
  -H "Authorization: Bearer $ALPHA_API_KEY"
```

## Response shape

Successful responses wrap the result in `data`. Errors include a stable code, a message, and the same request ID returned in the `X-Request-Id` response header.

```json
{
  "data": {
    "vaults": []
  }
}
```

Most data endpoints accept a `vault` field. Send the exact vault ID or name returned by `GET /v1/vaults`. When a credential can reach more than one vault, do not leave scope implicit.
