# Recipe: rate-limit handling

Recipe — rate-limit handling. Pointer to the SDK security guide.

Canonical guide: [`stratix-python/docs/security/rate-limiting.md`](https://github.com/layerlens/stratix-python/blob/main/docs/security/rate-limiting.md).

## Quick reference

The SDK auto-retries 429 with `Retry-After` honored. To handle directly:

```python
import layerlens
try:
 client.evaluations.create(model=model, benchmark=benchmark)
except layerlens.RateLimitError as e:
 retry_after = e.response.headers.get('retry-after')
 print(f"Rate limited. Retry after: {retry_after}s")
```
