## 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 agentdiet-html-to-markdown-converter-75b39a89
```

Example prompt: Fetch https://en.wikipedia.org/wiki/Artificial_intelligence and convert it to clean markdown so I can fit it in my context window without all the HTML bloat.

## When to prefer this

Choose this endpoint when you need to fetch a public URL and convert its HTML to LLM-friendly Markdown in a single call, especially when token budget is a concern. It is ideal for RAG ingestion, agent context window management, and any pipeline that needs to read web content without HTML overhead. Prefer it over generic scrapers when you specifically need Markdown output with built-in compression metrics.

## Known failure modes

- Invalid or unreachable URL returns an error status
- URL blocked by robots.txt or access controls may return empty or error
- Extremely large pages may time out or return partial content
- Malformed input schema (missing 'input' or 'method' field) returns validation error
- Payment failure (insufficient USDC balance) blocks the request via x402 protocol

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://rag-diet.agentdiet.dev settling in USDC on Base.

## Output

A JSON object with a 'data' field containing the converted Markdown text, a 'status' field ('ok' on success), and an 'roi_proof' object showing the compression_ratio_pct (e.g. 91.4%) achieved by stripping HTML down to clean Markdown.
