description: API rate limits and how to handle them
---

The Micro API enforces rate limits per API key to ensure availability for all users.

## Limits

| Limit               | Value |
| ------------------- | ----- |
| Requests per second | 10    |
| Requests per month  | 1,000 |

:::note These limits apply during the beta period and may change. Contact [support](mailto:support@micro.so) if you need higher limits for a specific use case. :::

## Handling 429s

When you exceed the limit, the API returns `429 Too Many Requests`. The `Retry-After` header tells you how many seconds to wait.

```
async function queryWithRetry(teamId: string, body: object, retries = 3) {
  const res = await fetch(`https://api.micro.so/v2/prism/query/${teamId}/contact`, {
    method: 'POST',
    headers: { 'x-api-key': apiKey, 'Content-Type': 'application/json' },
    body: JSON.stringify(body),
  });


  if (res.status === 429 && retries > 0) {
    const retryAfter = parseInt(res.headers.get('Retry-After') ?? '5', 10);
    await new Promise(r => setTimeout(r, retryAfter * 1000));
    return queryWithRetry(teamId, body, retries - 1);
  }


  return res;
}
```
