Difference Between 500 and 502

• 500 is broader. In CrazyRouter, it can mean either an internal server error on our side or an upstream 5xx that was returned through our relay.
• 502 is more specific. It usually means the request reached the gateway or upstream step, but CrazyRouter could not get a valid upstream response or fetch the upstream result, for example because the upstream was unavailable, returned an invalid gateway-level response, or the result URL could not be retrieved.
• If the same issue keeps happening:
  • frequent 502 errors usually point to upstream availability, connectivity, or result URL retrieval issues;
  • frequent 500 errors need log-based classification, and only cases explicitly marked as site-internal or panic-type should be treated as a CrazyRouter-side defect.

    for i in range(max_retries):
        response = requests.post(url, headers=headers, json=json_data)
        if response.status_code == 429:
            wait = 2 ** i
            print(f"Rate limited, waiting {wait} seconds before retrying...")
            time.sleep(wait)
            continue
        return response
    return response
