# Rate limits

> Per-key request limits and how to back off

Each API key is rate limited independently. The default ceiling is **100 requests per minute**.

Successful responses include the per-window maximum in the `X-RateLimit-Limit` header.

## When you hit the limit

Exceeding the limit returns `429 Too Many Requests` with a `rate_limit_error`:

```json theme={null}
{
  "error": {
    "type": "rate_limit_error",
    "code": "rate_limit_exceeded",
    "message": "Too many requests. Slow down."
  }
}
```

Back off and retry. A simple exponential strategy works well:

```js theme={null}
let delay = 1000;
for (let attempt = 0; attempt < 5; attempt++) {
  const res = await fetch(url, opts);
  if (res.status !== 429) return res;
  await new Promise((r) => setTimeout(r, delay));
  delay *= 2;
}
```

## Raising the limit

If your workload genuinely needs a higher ceiling — for example a large catalog backfill — contact support to discuss a per-organization increase.
