## 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 klymax402-html-to-markdown-converter-761e3f4d
```

Example prompt: Convert this HTML snippet into markdown for me: '<h1>Hello World</h1><p>This is a <strong>bold</strong> paragraph with a <a href="https://example.com">link</a>.</p>'

## When to prefer this

Choose this endpoint when you need a quick, cheap, no-setup HTML-to-markdown conversion via a pay-per-call model without managing API keys. Ideal for agents that occasionally need to process scraped HTML or convert documents on demand. Prefer this over local libraries when running in a serverless or sandboxed environment that lacks HTML-parsing dependencies.

## Known failure modes

- Empty or missing html parameter returns an error
- Malformed or non-HTML input may produce garbled or empty markdown output
- Extremely large HTML payloads may time out or be rejected
- Payment failure (insufficient USDC balance) results in HTTP 402 with no conversion performed
