# Rate limits

Rate limits protect API reliability and keep response times stable.

## How limits work

- Limits are applied per API token.
- When you exceed limits, API returns `429 Too Many Requests`.
- Use exponential backoff before retrying.

## Retry strategy

1. On `429`, wait and retry with backoff (`1s`, `2s`, `4s`, ...).
2. Add jitter to avoid retry spikes.
3. Stop retries after a maximum attempt threshold.

## Example backoff (pseudocode)

```text
attempt = 0
while attempt < 5:
  response = call_api()
  if response.status != 429:
break
  sleep((2 ^ attempt) + random_jitter)
  attempt += 1
```
