# Understand rate limits

> Understand API rate limits for Writer endpoints. Learn about RPM and TPM limits, best practices, and retry strategies for optimal performance.

</Info>

To ensure optimal service performance and fairness in resource allocation, our endpoints enforce the following rate limits.

1. **RPM (requests per minute)**: 400
2. **TPM (token per min)**: 25,000

## Best practices

<AccordionGroup>
  <Accordion title="Monitor request rates" icon="monitor-waveform">
    Implement mechanisms in your applications to track and regulate the
    frequency of your requests to stay within the prescribed limits.
  </Accordion>

  <Accordion title="Adaptive retry strategies" icon="rotate-right">
    In cases where you exceed these limits, employ adaptive retry strategies
    with exponential backoff to handle retries efficiently and reduce the
    likelihood of consecutive limit breaches.

    Prepare to handle HTTP 429 (too many requests) responses by pausing or
    slowing down request rates.
