| Issue | Cause | Solution |
|---|---|---|
| 404 for valid resource | Trailing slash mismatch | Normalize URLs |
| CORS errors | Missing headers | Configure CORS middleware |
| Slow pagination | Large offset | Use cursor pagination |
| Cache not working | Missing Vary header | Add Vary: Authorization |
