# URL Normalizer

> URL Normalizer is a paid API for AI agents from url-text-tools.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).

Normalizes a URL for de-duplication by lowercasing scheme/host, dropping default ports, resolving dot segments, and tidying percent-escapes.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability url-normalizer-1027cf30
```

Example prompt: Can you normalize this URL for me so I can deduplicate my list? Here it is: 'HTTP://Example.COM:80/foo/../bar?z=1&a=2#section' — please sort the query parameters and drop the fragment.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
