## 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 web-access-gateway-single-url-reader-a2f8c603 -d '<json body>'
```

Example prompt: Can you read the full page content at https://example.com/article and return the clean text along with a content hash so I can verify it later?

## When to prefer this

Choose this endpoint when you need to read the full content of a single, known public URL and require a SHA-256 hash for integrity verification or change detection. Prefer it over search-based endpoints when you already have the exact URL and want bounded, clean page text rather than search result snippets.

## Known failure modes

- URL is not publicly accessible or requires authentication — returns an error
- URL exceeds the 2048 character length limit — rejected at input validation
- Target page returns non-HTML content (e.g. PDF, binary) — content extraction may fail or be incomplete
- Rate limiting or blocking by target server — may return an empty or partial response
- Malformed or invalid URI — rejected at schema validation

## How this service works

Read one public URL and return clean bounded page content with a SHA-256 content hash.

## Output

Returns the clean, bounded text content extracted from the target public URL, along with a SHA-256 hash of that content for integrity verification and change detection.
