## 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 firstmention-webread-web-page-content-reader-261fb263 -d '<json body>'
```

Example prompt: Can you read the full text of this Wikipedia article on coffee — https://en.wikipedia.org/wiki/Coffee — and return it as markdown, up to 10000 characters?

## When to prefer this

Choose this endpoint when you need to extract structured content from any public webpage in a specific format (text, markdown, links, tables, JSON-LD, etc.) with precise character limits, and you want to pay per-call via USDC x402 without a subscription. Prefer it over general web search when you already have the URL and need the actual page content rather than a search result snippet.

## Known failure modes

- URL is not publicly accessible (private, behind auth wall) — returns non-200 status
- URL is malformed or unreachable — connection error
- Page returns non-HTML content (e.g. PDF, binary) — may return empty or partial main_text
- Character limit out of range (must be 200–60000) — validation error
- Rate limit or payment failure via x402 — 402 Payment Required response
