## 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 signaldesk-ai-url-query-string-sorter-4f044cb4 -d '<json body>'
```

Example prompt: Sort the query parameters in this URL alphabetically: https://example.com/?z=last&a=first&m=middle — I need the normalized version with the params in order.

## When to prefer this

Choose this endpoint when you need a lightweight, deterministic, server-side URL query-parameter sort without fetching the target resource. Ideal for URL canonicalization, cache-key generation, deduplication pipelines, or pre-signing normalization where consistent parameter ordering matters. It is not suitable if you need to fetch, scrape, or analyze the URL's content.

## Known failure modes

- Invalid or non-absolute URL returns an error (missing scheme or host)
- URL exceeding 2048 characters is rejected
- Malformed query string may produce unexpected ordering
- No network connectivity issues since URL is never fetched — only parsing errors apply

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object containing the input URL with its query parameters reordered alphabetically, e.g. {"url": "https://example.com/?a=1&z=2"}. The URL is parsed and reconstructed locally — no network request is made to the target URL.
