## Known failure modes

- Invalid or unsupported country code returns an error
- Non-numeric or malformed amount parameter causes a bad request
- Country without VAT (e.g. US) may return zero or an error
- Missing required query parameters results in a 400-level error
- Payment failure for the $0.002 USDC fee blocks the request
