## 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 email-verify-agentdiet-dev-web-url-to-markdown-distiller-with-bm25-8fdc3fc6
```

Example prompt: Fetch the page at https://stripe.com/docs/payments and distill it into Markdown, keeping it under 2000 tokens and focusing the BM25 budget on 'payment intents'.

## When to prefer this

Choose this endpoint when an AI agent needs to read a webpage but must stay within a token budget, or when you want to reduce LLM inference costs by compressing web content before passing it as context. Especially useful when you have a specific query focus (BM25 mode) or need structured JSON extraction from an HTML page. Prefer over raw fetch when token efficiency and cost savings are priorities.

## Known failure modes

- Invalid or unreachable URL returns an error status
- HTML payload too large may exceed processing limits
- BM25 budget mode requires both query and max_tokens parameters
- max_tokens below minimum of 20 is rejected
- Target site blocks scraping with 403 or CAPTCHA responses
- Malformed HTML input may produce incomplete distillation

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://email-verify.agentdiet.dev/v1/html-to-markdown)

## Output

Returns a JSON object containing the distilled content (Markdown text, structured JSON tables, skeleton outline, or BM25 excerpt depending on mode), along with ROI proof metrics including raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD. Also includes cache hit/miss status and billing details.
