## 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 agentdata-api-web-page-to-markdown-reader-87d68949 -d '<json body>'
```

Example prompt: Fetch the main content from https://www.bbc.com/news/technology-12345678 as clean markdown, capped at 15000 characters, so I can summarize it.

## When to prefer this

Choose this endpoint when you need to read the human-readable body of a specific known URL cheaply ($0.0015 per call) without an account or API key. It is the natural follow-up to /web/search when you have a URL and need its content. Prefer it over heavier scraping services when you only need the readable prose core rather than structured data or full DOM access.

## Known failure modes

- Unreachable URL (network error or DNS failure) — costs nothing, returns empty or error indicator
- Non-HTML target (PDF, binary file) — costs nothing, no content returned
- Page behind authentication or CAPTCHA — content inaccessible, may return partial or empty result
- max_chars too small — content is truncated and truncated flag is set to true
- Invalid URL format — request rejected before fetch

## How this service works

Read any web page as clean LLM-ready markdown for $0.003 — the natural companion to /web/search. Send a URL, get back the readable core: title, headings, paragraphs, lists and links, stripped of scripts, styles, navigation and other boilerplate. Choose markdown or plain text and cap the size with max_chars (default 20000; a truncated flag tells you when the cut hit). Unreachable or non-HTML targets cost nothing. Pay per call in USDC, no account, no API key.

## Output

Returns the page title, structured headings, paragraphs, lists, and links formatted as clean markdown (or plain text), with a truncated boolean flag if the content was cut at max_chars. Unreachable or non-HTML URLs return nothing and are not charged.
