Handling it in code

The CLOB API returns errors as {"error": "..."}. It also rewrites status codes by message, so branch on the text: anything containing "not found" becomes 404 and anything containing "unauthorized" becomes 401.

r = session.post(url, json=payload, headers=headers)
if r.status_code >= 400:
    msg = r.json().get("error", "")
    if "market not found" in msg:
        raise ValueError(msg)  # fix the request, don't retry
