With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability gedx402-browser-snapshot-4a46c28c ``` Example prompt: Grab a full rendered HTML snapshot of https://news.ycombinator.com — wait until the network is idle before capturing so all dynamic content loads. ## When to prefer this Choose this endpoint when you need the fully rendered (post-JavaScript) HTML of a web page without managing API keys. It's ideal for scraping JS-heavy single-page applications where a simple HTTP GET won't return meaningful content, and when you want to pay per-call with USDC across Base, Polygon, Arbitrum, World, or Solana rather than managing a subscription. ## Known failure modes - Invalid or unreachable URL returns an error response - Payment failure or insufficient USDC balance blocks the request - Timeout if the page takes too long to load or network never becomes idle - Malformed HTML input may produce unexpected render output - HTTPS-only URLs required; HTTP URLs may be rejected ## How this service works x402 workers ai. pay with usdc on base, polygon, arbitrum, world, or solana. no api keys. ## Output Returns a JSON object containing the fully rendered HTML of the requested page after JavaScript execution, e.g. {"html": "..."}. The HTML reflects the page's DOM state post-render, including any dynamically injected content. ## Request schema (JSON Schema) ```json { "type": "object", "properties": { "url": { "type": "string", "description": "HTTPS URL to load (required unless html is set)." }, "html": { "type": "string", "description": "Raw HTML to render instead of fetching a URL." }, "prompt": { "type": "string", "description": "Natural-language extraction prompt (for /json)." }, "elements": { "type": "array", "items": { "type": "object" }, "description": "Scrape selectors (for /scrape)." }, "selector": { "type": "string", "description": "CSS selector for element capture or scrape." }, "viewport": { "type": "object", "description": "Browser viewport width/height/deviceScaleFactor." }, "pdfOptions": { "type": "object", "description": "PDF print options." }, "gotoOptions": { "type": "object", "description": "Puppeteer goto options (e.g. waitUntil: networkidle0)." }, "response_format": { "type": "object", "description": "JSON schema for structured /json extraction." }, "screenshotOptions": { "type": "object", "description": "fullPage, type, omitBackground, etc." } } } ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "html": "..." } } ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/gedx402-browser-snapshot-4a46c28c/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from browser.gedx402.com](https://www.zero.xyz/host/browser.gedx402.com/llms.txt)
