How this service works
Normalize a URL for de-duplication: lowercase scheme/host, drop default port, resolve dot segments, tidy %-escapes.
Output
Returns the normalized URL alongside the original input, a count of how many changes were made, a list of reasons describing each normalization applied, a plain-English summary, a verdict, and any disclaimer about limitations. Also includes an 'asOf' timestamp and a 'degraded' flag if the service is running in a reduced-quality mode.
Example use cases
Deduplicating a crawled URL dataset
“I've been scraping pages and my URL list has duplicates because some have uppercase schemes, trailing dots, or default ports. Can you normalize all these URLs so I can deduplicate them properly? Start with this one: 'HTTP://News.Example.COM:80/articles/../2024/story?ref=home'”
Canonical URL for SEO or caching
“Before I store this URL in my cache index, can you give me its canonical normalized form? The URL is 'https://BLOG.EXAMPLE.com:443/posts/./my%20post%20title?b=2&a=1' — also sort the query params so the key order doesn't matter.”
Cleaning URLs before comparison
“I need to compare two URLs to see if they point to the same resource, but they look different because of encoding and case differences. Can you normalize 'Http://Example.org/path/%61%62c' for me so I can do a reliable string comparison?”
Technical details
Endpoint
GEThttps://url-text-tools.x402tookit.com/url-normalize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to canonicalize URLs for deduplication, comparison, or storage — especially when your URLs may differ only in scheme case, host case, default port presence, dot segments, or percent-encoding style. Prefer it over manual string manipulation when you need documented, RFC-compliant normalization with an audit trail of exactly what changed and why.
Side effects
- Missing or malformed 'url' query parameter returns an error
- Non-absolute URL (relative URL) may return an error or unexpected result
- Unsupported URL schemes may not normalize correctly
- Network or service errors returning 4xx/5xx HTTP responses
- Malformed percent-encoding in input may cause parse failures
