## 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-markdown-renderer-def248ac -d '<json body>'
```

Example prompt: Can you convert this markdown text to HTML for me: '# Hello World

This is a **bold** statement and here is a [link](https://example.com).'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call markdown-to-HTML conversion without committing to a subscription. Ideal for agents that only occasionally need markdown rendering and want to pay micro-amounts (fractions of a cent) per call via USDC on Base rather than managing API keys or monthly plans.

## Known failure modes

- Payment not provided or insufficient USDC balance — 402 Payment Required
- Malformed or missing markdown input body — 400 Bad Request
- Rate limiting or gateway downtime — 503 Service Unavailable
- Invalid x402 payment header — payment rejected by facilitator
