Rate limits

The limit is per organization, not per key: creating a second key doesn't buy you a second budget. That's deliberate — the budget belongs to the account, and splitting it by credential would mean the load on our side depends on how many keys somebody happened to create.

Both are evaluated, and whichever runs out first is the one that stops you. There's also a wide per-IP backstop, high enough that it only catches a single machine flooding us — a partner integrating many organizations from one server won't meet it.

What a 429 looks like

HTTP/1.1 429 Too Many Requests
Retry-After: 24

{ "error": { "code": "API_KEY_RATE_LIMITED", "message": "Rate limit exceeded for this API key." } }

Retry-After is in seconds and it's the real number — waiting that long is enough. Read it instead of guessing a backoff: a fixed sleep is either slower than it needs to be or not long enough.

async function call(url, init) {
  for (let attempt = 0; attempt < 5; attempt++) {
    const res = await fetch(url, init);
    if (res.status !== 429) return res;
    const wait = Number(res.headers.get("Retry-After") ?? 5);
    await new Promise((r) => setTimeout(r, wait * 1000));
  }
  throw new Error("Still rate limited after 5 attempts");
}

Staying under it

• Ask for bigger pages. limit=100 reads four times as much per request as the default 25 — see Pagination.
• Poll on a schedule, not in a loop. There are no webhooks yet, so polling is the pattern; the mistake is polling as fast as the code can run rather than as fast as the data changes.
• Handle the 429 rather than avoiding it. A retry that reads Retry-After is more robust than a rate you tuned once and never revisited.
