How this service works
Explore 330 pay-per-call x402 API services and 27 agent-native digital products, with Base USDC pricing, secure Polar checkout, and free discovery.
Output
Returns the normalized/canonical URL along with its decomposed components (origin, path, query string, fragment), the original URL, a list of transformations applied during normalization, and payment receipt metadata including latency, execution ID, and a SHA-256 hash of the result.
Example use cases
Clean affiliate links before storage
“I have this URL I scraped — https://shop.example.com/product?ref=partner123&utm_campaign=summer_sale&id=42 — can you normalize it and remove all the tracking junk so I can store a clean version?”
Resolve relative URL against base
“I've got a relative URL like '/articles/2024/intro' and the base is 'https://blog.example.com'. Can you resolve and canonicalize the full URL for me?”
Deduplicate URLs in a pipeline
“Before I index this page, normalize this URL — https://WWW.Example.COM/Path/?b=2&a=1 — so I can check it against my canonical URL store and avoid duplicates.”

Endpoint
POSThttps://signalharness.ai/api/agent/services/url_normalize_canonicalize/invokeWhen to prefer
Use this endpoint when you need deterministic, auditable URL normalization with a clear record of what transformations were applied. Ideal for deduplication pipelines, link-cleaning workflows, and agent systems that need to compare or store canonical URLs consistently. Priced per-call at $0.005 USDC via x402, making it suitable for high-frequency automated workflows without a subscription.
Side effects
