aster-api-errors-v3

To handle Aster Futures API error codes, parse JSON payloads by numeric code and map them to stable categories like 10xx, 11xx, 20xx, and 40xx for deterministic retry or fail decisions. This prevents unexpected crashes when interpreting v3 API responses.

When Aster Futures API returns HTTP 429, apply exponential backoff to reduce request weight. If you receive HTTP 418, your IP has been banned due to repeated rate limit violations, requiring a pause in traffic until the ban lifts.

X-MBX-USED-WEIGHT and X-MBX-ORDER-COUNT headers track REQUEST_WEIGHT per IP and ORDERS per account respectively. Monitoring these headers lets clients throttle REST calls proactively and avoid hitting Aster Futures rate limits.

Aster Futures API error -1022 indicates a signature failure, while -1021 signals a timestamp issue, often caused by clock drift. Correcting your HMAC signature and synchronizing server time resolves these reliability failures.

Yes, an HTTP 503 from Aster Futures API may indicate that the request was actually processed despite the error. Clients should treat 503 cautiously and verify state before blindly retrying the operation to avoid duplicates.

To reduce REST rate limit pressure on Aster Futures API, prefer using WebSocket streams for market data and throttle REST calls. This lowers request weight and helps avoid triggering HTTP 429 bans.
