## Error Handling

```javascript
try {
  const res = await client.fetchUserReactions({
    fid: 123,
    type: "value"
  });
  // use res
} catch (err) {
  // Axios/HTTP errors, invalid params, auth issues, etc.
  console.error(err);
}
```

## Tips

- Provide a **viewerFid** when supported to respect mutes/blocks and include `viewer_context`.
- Keep requests scoped (e.g., use `limit`) to improve latency.
- Cache results where sensible.
