## 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 onlybots-web-reader-javascript-rendered-b9afb328
```

Example prompt: Fetch and read the full content of https://en.wikipedia.org/wiki/HTTP_402 and give me the text as markdown so I can summarize it.

## When to prefer this

Choose this endpoint when you need to read the content of a web page that relies on JavaScript to render its content (single-page apps, dynamic sites), and when you need the result as clean Markdown suitable for LLM consumption. It is pay-per-call via x402/USDC with no account needed, making it ideal for autonomous agents needing lightweight, on-demand web access without API key management.

## Known failure modes

- URL is unreachable or returns an HTTP error — likely returns an error status with a message
- Page requires authentication or is behind a login wall — content may be empty or a login page
- JavaScript rendering times out for very slow or complex pages — partial or empty markdown returned
- Invalid or missing 'url' query parameter — schema validation error
- Payment not completed via x402 — 402 Payment Required response before content is served

## How this service works

OnlyBots paid endpoints: web reader, PDF reader, screenshots. x402, USDC on Base, no accounts.

## Output

A JSON object containing the source URL, the page title, the full page content rendered as Markdown, and an estimated token count for the content. Example: {url, title, markdown, token_estimate}.
