## 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 delx-commerce-page-links-summary-html-regex-extract-388f105b -d '<json body>'
```

Example prompt: Here's the raw HTML I fetched from a page — can you extract all the links from it, up to 50, and give me the list?

## When to prefer this

Choose this endpoint when you already have raw HTML content in memory and need a fast, cheap ($0.002 USDC), no-signup link extraction without spinning up a headless browser. Ideal for pipeline steps in an agent crawl loop where you've already fetched HTML and need to enumerate links for further processing. Not suitable if you need JavaScript-rendered links or full page rendering.

## Known failure modes

- Malformed or empty HTML input may return an empty links array with count 0
- JavaScript-rendered content will not be extracted since this is regex-based, not a headless browser
- Very large HTML strings may hit request size limits
- Limit parameter set to 0 or negative values may produce unexpected behavior
- Relative URLs (e.g. /about) are returned as-is without being resolved to absolute URLs

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output
