## 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-markdown-distiller-with-bm25-84278ed1
```

Example prompt: Can you distill https://docs.stripe.com/api into compact markdown using budget mode, focusing on 'payment intents', and keep it under 2000 tokens?

## 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 raw HTML would be too verbose and costly to pass directly to an LLM. Especially useful for injecting live documentation, news pages, or research articles into agent context windows efficiently. Prefer the budget+BM25 mode when only a specific topic within a large page is needed.

## Known failure modes

- Invalid or unreachable URL returns an error status
- HTML too large or malformed may degrade distillation quality
- mode=budget without a query or max_tokens may produce unoptimized output
- Rate limits or payment failures (HTTP 402) block the request
- Sites with bot protection or paywalls may return incomplete content

## 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/docs-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), along with an roi_proof block showing raw vs. distilled token counts, compression ratio, tokens saved, and estimated LLM cost saved in USD. Also includes cache status (HIT/MISS) and billing details.
