## 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 polymarket-odds-agentdiet-dev-web-url-to-compact-markdown-distiller-9b114627
```

Example prompt: Fetch https://stripe.com/docs/payments and distill it into compact markdown, keeping it under 2000 tokens and focusing on the BM25 query 'payment intents API' so I can use it in my prompt without blowing my context window.

## When to prefer this

Choose this endpoint when you need to fetch and compress web pages into LLM-friendly tokens with a strict budget, especially when cost efficiency (tokens saved, LLM cost reduction) is a priority. It is ideal for agent workflows that need to read web content without exhausting context windows, and when structured output modes (tables, skeleton, BM25 excerpt) are more useful than raw HTML scraping. Prefer it over generic scraping endpoints when token budget control and ROI metrics matter.

## Known failure modes

- Invalid or unreachable URL returns an error status
- URL blocked by robots.txt or anti-scraping measures may return empty or partial content
- max_tokens set too low may truncate content aggressively
- BM25 query with mode=budget but no relevant content returns minimal excerpt
- Raw HTML too large may exceed processing limits
- Payment/billing failure via x402 returns 402 status blocking the response

## How this service works

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

## Output

Returns a JSON object containing the distilled content (markdown text, structured JSON tables/metadata, skeleton outline, or BM25-focused excerpt depending on mode), plus an ROI proof object showing raw vs. distilled token counts, tokens saved, compression ratio percentage, estimated LLM cost saved, and a cache status object indicating whether the result was served from cache.
