## 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 agent-web-reader-web-content-extractor-x402-1f2a827f
```

Example prompt: Can you read the contents of https://techcrunch.com/2024/05/01/openai-launch/ and give me a summary of what the article says?

## When to prefer this

Use this endpoint when an AI agent needs to read and extract the textual content of any arbitrary public web URL at low cost ($0.002/call) without maintaining an API key, especially in pay-per-use autonomous agent pipelines using x402/USDC on Base for micropayments.

## Known failure modes

- URL is unreachable or returns a non-200 status — likely a 4xx/5xx from the upstream site
- URL is missing or malformed — 400 bad request
- Payment not settled or insufficient USDC balance — 402 payment required
- Target page requires JavaScript rendering — extracted text may be empty or incomplete
- Rate limiting or blocking by the target website — partial or empty content returned

## How this service works

Web-content reader: fetch any http(s) URL and return clean readable text, title/description/canonical, and outbound links as JSON — the data an agent ingests on each step of a crawl or RAG loop. Input: url.

## Output

Returns a JSON object with: kind (e.g. 'html'), extracted plain text of the page body, a list of links found on the page, the page title, word count, and meta description. Payment of $0.002 USDC is settled automatically per call via x402 on Base.
