- Invalid or malformed query path results in upstream 400 or 404 error
- Bing Copilot upstream service unavailable returns 502/503 passthrough
- x402 payment facilitator timeout causes transaction failure
- Rate limiting by upstream Bing API returns 429 passthrough
- Empty or missing query parameter yields no results or upstream error
