## 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 extract-ids-as-json-0460142b
```

Example prompt: Can you fetch https://example.com and give me a JSON list of all the HTML element IDs on that page?

## When to prefer this

Choose this endpoint when you need a clean, structured JSON list of HTML element IDs from a single page without spinning up a headless browser. It is ideal for lightweight pipeline steps, UI audits, anchor-link verification, and automated test-selector discovery where only the id attributes matter and you don't need other page content.

## Known failure modes

- URL is unreachable or returns non-200 status — empty result or error response
- Page has no ID attributes — returns empty array with count 0
- URL is malformed or missing — request fails with validation error
- Page requires JavaScript rendering — IDs injected by JS may not be captured since no browser is used
- Rate limiting or payment failure for the $0.01 USDC x402 charge — request blocked

## How this service works

Extract the page's ids as json: fetches the URL, pulls every ids element and returns them as a JSON array, with a count. Structured, one-element-type extraction for agents and pipelines; no browser needed. $0.01 per page.

## Output

A JSON array of all HTML element ID attribute values found on the fetched page, accompanied by a count of how many IDs were discovered. The response is structured and machine-readable, suitable for direct use in pipelines or agent workflows.
