## 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-services-x402-js-renderer-31ab34da -d '<json body>'
```

Example prompt: Can you load https://example.com/dashboard and extract all the visible text after the JavaScript has finished running — wait up to 6000ms for it to fully render and cap the output at 15000 characters?

## When to prefer this

Choose this endpoint when the target page is a single-page application or uses client-side rendering (React, Vue, Angular, etc.) and a plain HTTP GET would return an empty shell. It is ideal for agents that need to extract text or links from dynamic pages and are willing to pay $0.005 per call via x402 USDC on Base. Prefer it over static scrapers when JavaScript execution is required to see real content.

## Known failure modes

- URL is unreachable or returns a non-200 status — error field populated
- Page JavaScript throws errors preventing render — partial or empty text returned
- wait_ms too short for slow SPAs — incomplete content returned
- URL is malformed or missing — request rejected with validation error
- Payment via x402 not provided or insufficient — HTTP 402 returned before processing

## How this service works

Paid per-call web tools for AI agents: DNS, TLS, robots.txt, hashing, JavaScript rendering and screenshots. Payment over x402 (USDC on Base).

## Output

Returns a JSON object with the rendered page's visible text (capped at max_chars), the page title, an array of links found on the page, the character count of returned text, and an error field if rendering failed.
