## 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 gedx402-browser-html-renderer-da65558e
```
Example prompt: Load https://news.ycombinator.com in a headless browser and give me the full rendered HTML of the page, waiting until the network is idle.
## When to prefer this
Use this endpoint when you need the JavaScript-rendered HTML of a page (not just the static source), especially for single-page apps or dynamically loaded content, and you want to pay per-call with USDC crypto on Base, Polygon, Arbitrum, World, or Solana without managing API keys.
## Known failure modes
- Invalid or unreachable URL returns an error response
- Missing both url and html parameters causes a bad request
- Payment failure or insufficient USDC balance blocks the request
- Timeout if the page takes too long to load
- Non-HTTPS URLs may be rejected
