- Invalid or unsupported path yields a 404 or upstream error response
- Malformed query parameters may cause upstream to return an error payload
- x402 facilitator unavailability blocks payment settlement and prevents request forwarding
- Rate limits or authentication issues on the upstream RapidAPI BB Finance tier return error codes
