## 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 httpay-markdown-to-html-converter-fbb797cd -d '<json body>'
```

Example prompt: Convert this markdown to HTML for me, with GitHub Flavored Markdown enabled and line breaks turned on: '# Hello World\n\nThis is **bold** and this is a list:\n- item 1\n- item 2'

## When to prefer this

Choose this endpoint when you need a quick, serverless, pay-per-call markdown-to-HTML conversion without managing API keys or subscriptions. Ideal for agents that occasionally need to render markdown and don't want to bundle a markdown parser or set up a persistent service. Useful when GFM (GitHub Flavored Markdown) compatibility is needed.

## Known failure modes

- Missing or invalid markdown body returns an error response
- Malformed JSON in request body causes a 400-level error
- Extremely large markdown payloads may time out or be rejected
- Payment failure (insufficient USDC balance or x402 not supported) results in 402 Payment Required

## How this service works

307 pay-per-call APIs (287 native + Universal Gateway proxying 37 services) powered by x402 and USDC on Base. Token intelligence, DeFi yields, MEV risk, AI tools, web scraping. No API keys, no subscriptions — pay $0.001–$0.05 per call.

## Output
