# rate_limited

> Too many requests.

Source: https://tickwire.io/docs/errors/rate_limited/

HTTP 429. Nothing reached the broker.

**Likely causes:**

- The per-key, per-account, per-account trade or per-IP budget is used up (metadata.bucket names it).
- A heavy call (history, batch, stream connect) costs more than one unit.
- Too many sandbox sign-ups from one address in an hour or a day, or from everyone in an hour (POST /v1/sandbox/signup).

**What to do:** Wait for Retry-After, then retry. A refused trade carries sent: false: it was not sent, so it is safe to resend. See the rate-limits page.

**Retry:** Yes. Nothing happened (or it was a read), so repeat it, after `Retry-After` when present.
