```

## Known failure modes

- Invalid or missing snapshot identifiers returns an error
- Snapshots from incompatible index versions may produce unreliable diffs
- Requesting snapshots that do not exist returns a not-found error
- Malformed request body results in a 400-level validation error
- Payment failure via x402 protocol blocks the request entirely
