## 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 axon-markdown-renderer-a3b9497d
```

Example prompt: Convert this markdown text to HTML for me: '# Bitcoin Analysis\n\nBTC is trading at $65,000 with strong momentum.' and give me the character count too.

## When to prefer this

Choose this endpoint when you need to convert markdown-formatted text to HTML with character count metadata, particularly within workflows already using Axon's x402-based crypto intelligence suite. It is a lightweight, pay-per-call conversion step costing $0.02 USDC on Base, suitable for rendering AI-generated markdown reports, crypto research summaries, or any structured text into display-ready HTML.

## Known failure modes

- Missing or malformed 'properties' input returns an error or empty HTML
- Invalid markdown syntax may render partially or produce unexpected HTML
- Missing x402 micropayment header results in 402 Payment Required response
- Network timeout on Vercel serverless cold start
- Empty input returns minimal or empty HTML with charCount of 0

## How this service works

Axon provides AI-powered crypto intelligence endpoints covering token research, market analysis, contract auditing, sentiment tracking, news summarization, portfolio advice, deep research, text translation, language detection, SEO content generation, and contract explanation. All analytical endpoints require x402 micropayment on Base.
