## 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-tollgate-engine-web-render-url-to-markdown-21f70212
```

Example prompt: Can you fetch the content of https://example.com/article and give me the full text as markdown, up to 50000 characters?

## When to prefer this

Choose this endpoint when you need to retrieve and read the textual content of a public webpage in a clean, agent-friendly Markdown format, especially within an x402 micropayment workflow on Base, Polygon, or Solana. Prefer it over full browser automation when you don't need JavaScript rendering or interactive elements — it's fast and cheap at $0.01 USDC per call. It's part of a broader 50-tool suite on the same platform, so ideal when you're already using Agent Tollgate Engine for other tasks like crypto data or DNS lookups.

## Known failure modes

- URL is not publicly accessible (private, behind auth, or paywalled) — returns error or empty content
- URL is malformed or non-HTTP/HTTPS — schema validation failure
- Page renders no meaningful text (JS-heavy SPA with no SSR) — sparse or empty markdown returned
- maxChars exceeded the 150000 maximum — request rejected
- Target server is down or rate-limiting — fetch timeout or connection error
- Payment not settled via x402 before request — 402 Payment Required response

## How this service works

50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.

## Output

A JSON object containing a 'markdown' field with the rendered page content converted to Markdown format, truncated to the requested maxChars limit (default 30000, max 150000).
