## 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 onchain-trading-intelligence-html-to-markdown-converter-3be7c601 -d '<json body>'
```

Example prompt: I have some raw HTML scraped from a DeFi dashboard — can you convert it into clean markdown so I can feed it into my trading analysis pipeline?

## When to prefer this

Choose this endpoint when you need to programmatically convert raw scraped HTML into readable Markdown for downstream LLM or agent processing, especially within an onchain/trading intelligence pipeline that already uses the x402 pay-per-call stablecoin payment model. It fits naturally when your agent has already scraped a DeFi, DEX, or tokenized-equity page and needs clean text before analysis.

## Known failure modes

- Empty or missing 'html' field returns a validation error
- Malformed or extremely large HTML may cause parsing timeouts
- Non-HTML input (e.g. plain text or JSON) may produce garbled or trivial markdown output
- x402 payment failure (insufficient balance or unsupported stablecoin) blocks the call before processing

## How this service works

Convert raw HTML to clean, LLM-ready markdown. Strips nav/script/style noise.

## Output

A clean Markdown-formatted version of the submitted HTML, with HTML tags stripped and content structured for human or LLM readability.
