## 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 x402-utility-tools-html-link-extractor-7f8a0ba5 -d '<json body>'
```

Example prompt: Pull all the links out of this HTML snippet and resolve them against https://x402-utils.558686.xyz as the base URL: '<a href="/docs">Docs</a><a href="/api">API</a>'

## When to prefer this

Choose this endpoint when you need a cheap, fast, deterministic link extraction from raw HTML without spinning up a headless browser or calling an LLM. It is ideal for pipelines that parse crawled pages, validate generated HTML, or build link graphs at scale. At $0.002/call it is cost-effective for high-volume repeatable extraction tasks where accuracy is sufficient from static HTML parsing alone.

## Known failure modes

- Malformed or non-string HTML input may return an error or empty links array
- Missing baseUrl may leave relative URLs unresolved or cause parsing errors
- Very large HTML payloads may be rejected or time out
- Non-HTML content passed as the html field may yield zero links
- Invalid baseUrl format may cause URL resolution failures

## How this service works

A compact x402 utility surface for agents that need cheap, repeatable non-LLM transformations before spending on heavier routes: CSV cleanup, JSON Schema checks, timestamp conversion, JWT decode, URL normalization, hashes, codecs, and text utilities.

## Output

Returns a JSON object with 'ok' status, the tool name, echoed input, the route used, and a 'result' object containing 'count' (integer number of links found) and 'links' (array of extracted/resolved absolute URL strings). The response is deterministic for the same input.
