## 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 evidence402-web-read-586814d5 -d '<json body>'
```

Example prompt: Can you read the content of this page for me — https://www.bbc.com/news/world-us-canada-68000000 — and pull out the full article text and title?

## When to prefer this

Choose this endpoint when you need to retrieve and read the text content of a specific public webpage without managing browser infrastructure yourself, especially when you want a tamper-evident content hash for auditing or citation verification. It is ideal for research agents, fact-checking pipelines, and any workflow needing a lightweight, pay-per-call web read without a standing API subscription.

## Known failure modes

- URL is behind a paywall or login — returns no usable content or empty text
- Page uses heavy JavaScript rendering — static extraction may miss dynamically loaded content
- URL is unreachable or returns a non-200 HTTP status — request fails with an error
- Rate limits or bot-blocking on the target site may cause retrieval failures
- Invalid or malformed URL input causes a request error
