## 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 markdown-to-html-converter-b12f009d -d '<json body>'
```

Example prompt: Convert this markdown file to HTML for me — the input format is md and I need it back as an html file.

## When to prefer this

Choose this endpoint when you need a simple, pay-per-use Markdown-to-HTML conversion with no setup or API key management, particularly in automated agent workflows that support the x402 micropayment protocol. It is ideal for one-off document conversions at low cost ($0.01 USDC) without committing to a subscription service.

## Known failure modes

- Invalid or missing 'from' field (must be 'md') — returns validation error
- Invalid or missing 'to' field (must be 'html') — returns validation error
- Empty or malformed markdown file content — may return empty or partial HTML
- Payment not completed via x402 protocol — returns 402 Payment Required
- Service unavailable on Railway deployment — returns 5xx error
