Rate Limits

The Loopwave API limits each key to a fixed number of requests per minute so a single integration can’t overwhelm your deployment.

The limit

Each key has its own budget, so issuing separate keys for separate integrations keeps their limits independent.

Response headers

Every response includes how much budget is left, and a 429 tells you when to retry:

Handling 429

When you exceed the limit you receive:

{ "error": "rate_limited", "message": "Too many requests for this key." }

Respect the Retry-After header and back off before retrying.

async function callWithRetry(url, opts) {
  const res = await fetch(url, opts);
  if (res.status === 429) {
    const wait = Number(res.headers.get('Retry-After') || 1) * 1000;
    await new Promise((r) => setTimeout(r, wait));
    return callWithRetry(url, opts);
  }
  return res;
}
