## 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-public-page-fetcher-0a0fb6fe
```

Example prompt: Fetch the public page at https://example.com and give me the title, all the links, and any metadata you find on it.

## When to prefer this

Choose this endpoint when you need to quickly fetch, parse, and extract structured data (title, links, metadata) from any publicly accessible HTTPS webpage without setting up a full browser or crawler. Ideal for lightweight page inspection tasks where you only need the public surface of a URL rather than JavaScript-rendered content or deep crawl capabilities. Best for single-URL lookups at low cost ($0.004 per call).

## Known failure modes

- Non-HTTPS or malformed URL returns a validation error
- URL shorter than 8 characters rejected by schema
- Page behind authentication or paywalls may return empty or partial content
- Timeout or network errors from Cloudflare Workers runtime
- Non-public pages (e.g. localhost or internal IPs) may be blocked
- Payment not received results in HTTP 402 and no content returned

## 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 page URL, page title, an array of links (each with href and anchor text), a metadata object, the timestamp when the page was fetched, and an untrusted_content boolean flag indicating the content is third-party and should not be implicitly trusted.
