## 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 agentshelf-syntexa-ch-utm-stripper-6412c74d -d '<json body>'
```

Example prompt: Strip all UTM and tracking parameters from this URL: https://example.com/page?utm_source=newsletter&utm_medium=email&utm_campaign=spring_sale&fbclid=abc123

## When to prefer this

Choose this endpoint when you need a fast, purely local (no network) transformation to strip UTM and tracking parameters from a URL. It is ideal for pre-processing URLs before storage, deduplication, or sharing, and costs only $0.001 USDC per call. Prefer the free sandbox POST /v1/sandbox/strip-utm if available.

## Known failure modes

- URL shorter than 8 characters returns a validation error
- URL longer than 2048 characters is rejected
- Malformed or non-URL string input returns an error
- If the URL has no tracking parameters, the original URL is returned unchanged

## How this service works

Call when an agent needs tracking query parameters stripped from a URL. No network. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/strip-utm first.

## Output

A cleaned URL string with all UTM and tracking query parameters removed (e.g. utm_source, utm_medium, utm_campaign, utm_term, utm_content, fbclid, gclid), preserving all non-tracking query parameters and the rest of the URL structure intact.
