## 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 x402-gateway-html-to-markdown-e35f14ee -d '<json body>'
```

Example prompt: Take this HTML I scraped from the page and convert it to clean Markdown so I can feed it into my LLM pipeline: <html><body><h1>Hello World</h1><p>This is a test.</p></body></html>

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call HTML-to-Markdown conversion with no account setup or API key management. It is well-suited for AI agent pipelines that process web content on demand and want to pay only for what they use in USDC on Base. Prefer this over self-hosted solutions when you want zero infrastructure overhead and deterministic per-call pricing.

## Known failure modes

- Malformed or empty HTML input may produce garbled or empty Markdown output
- Payment failure (402) if the agent does not supply valid USDC payment on Base
- Missing or incorrect 'tool' field in the request body returns an error
- Very large HTML documents may time out or be truncated
- Non-HTML input passed as HTML may produce unexpected results
