## When to prefer this

Choose this endpoint when you need a reliable, consistent canonical form of a URL — especially useful for deduplication, caching keys, or comparison workflows where URLs from different sources may encode the same resource differently. Prefer this over ad-hoc string manipulation when correctness and quality scoring matter.

## Known failure modes

- Missing or empty URL input returns a validation error
- Malformed URLs that cannot be parsed may return an error or unexpected result
- URLs exceeding 8192 characters will be rejected
- Network timeouts or worker errors may return 5xx responses
- Payment failure via x402 protocol will block the request
