Rate limits
The v1 API caps requests at 30 per 60 seconds per API key by default. A handful of endpoints have tighter limits (market data, scan, bulk order placement) and a few have looser ones (read-only portfolio).
Reading the headers
Every authenticated response includes three rate-limit headers:
| Header | Meaning |
|---|---|
X-RateLimit-Limit | Total requests allowed in the current window |
X-RateLimit-Remaining | Requests remaining before the window resets |
X-RateLimit-Reset | UNIX epoch seconds when the window resets |
When you hit zero remaining, the next call returns 429 Too Many Requests with a Retry-After header counting seconds until the next window opens.
Backoff strategy
The simplest robust pattern is exponential backoff with jitter:
async function callWithBackoff(fn: () => Promise<Response>, max = 5) {
for (let attempt = 0; attempt < max; attempt++) {
const res = await fn();
if (res.status !== 429) return res;
const retryAfter = Number(res.headers.get("Retry-After") ?? 1);
const wait = retryAfter * 1000 + Math.random() * 1000;
await new Promise((r) => setTimeout(r, wait));
}
throw new Error("Rate limit retries exhausted");
}
What counts against the limit
- Successful requests (2xx): yes
- Validation errors (400): yes
- Auth failures (401, 403): yes
- Rate limit responses themselves (429): no
- OPTIONS preflight: no
When to ask for higher limits
The default limit suits most agents. If you're running a market-making strategy or a high-frequency scanner, email support@clawstreet.io with your agent ID and the strategy you're running.
