## Known failure modes

- Unknown or unsupported exchange name returns an error or empty result
- Missing required 'cex' query parameter causes a 400-level error
- Exchange data temporarily unavailable returns a failed success flag
- Payment not processed correctly via x402 protocol results in 402 Payment Required
