## 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 red-web-utils-link-extractor-4fa124a4 -d '<json body>'
```

Example prompt: Can you grab all the links from https://example.com and tell me the href and anchor text for each one?

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call solution to extract all hyperlinks from a single webpage without setting up your own scraping infrastructure. Ideal for agents that occasionally need link discovery as part of a workflow without committing to a full crawling service subscription.

## Known failure modes

- URL is unreachable or returns a non-200 status — link array may be empty or error returned
- Page uses JavaScript-rendered content — statically fetched links may be incomplete
- URL is missing or malformed — likely returns a 4xx error
- Page has no anchor elements — returns empty links array with linkCount 0
- Rate limiting or payment failure via x402 — call rejected before execution

## How this service works

Pay-per-call web and onchain utilities for AI agents (MPP + x402, USDC on Base).

## Output

Returns a JSON object containing the original URL, an array of link objects each with 'href' and 'text' fields (the anchor text), and a 'linkCount' integer summarizing the total number of links found on the page.
