How this service works
Machine-readable settlement service
Output
Returns a cleaned, canonical URL string with normalized scheme, host casing, resolved path segments, sorted or stripped query parameters, and standardized formatting, as a JSON object.
Example use cases
Strip tracking params from shared link
“Take this URL and clean out all the tracking parameters so I have a plain canonical link: https://shop.example.com/product/shoes?utm_campaign=summer&utm_source=email&utm_medium=cpc”
Fix malformed URL before storage
“Before I save this URL to my database, can you normalize it so it's properly formatted and canonical: 'HTTP://WWW.EXAMPLE.COM:80/foo//bar/../baz?z=3&a=1'”
Deduplicate URLs by canonical form
“I have two URLs that might be the same page — can you normalize both of them so I can compare: 'https://example.com/page?a=1&b=2' and 'https://EXAMPLE.COM/page?b=2&a=1'”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/url.normalize--clean-urlWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call URL normalization without standing up your own parsing infrastructure. Best suited for single-URL normalization in pipelines where canonical URL deduplication or clean link storage is needed, especially when already integrated with x402 micropayment flows.
Side effects
- Empty or missing input string returns validation error
- Non-URL string input may return error or unexpected output
- Extremely long or malformed inputs may fail to parse
- Network timeout if the PennyRail service is unavailable
- Payment failure (x402) if USDC balance is insufficient
