# Web URL Markdown Distiller with BM25 Budget Control

> Web URL Markdown Distiller with BM25 Budget Control is a paid API for AI agents from github-audit.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown.

Fetches a webpage (or accepts raw HTML) and distills it into compact, agent-ready Markdown, structured JSON, skeleton outline, or BM25-focused token budget excerpts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 github-audit-agentdiet-dev-web-url-markdown-distiller-with-bm25-9be89dcc
```

Example prompt: Distill the content at https://stripe.com/docs/payments into compact markdown using budget mode, focused on 'payment intents', and keep it under 500 tokens.

## When to prefer this

Choose this endpoint when an AI agent needs to read a webpage but must conserve context window tokens or LLM costs. It is especially useful when the target page is long or noisy, and the agent only needs the relevant portion (use budget+query mode). Prefer this over raw HTTP fetching when structured extraction (tables, metadata) or outline-only views are needed. Also ideal when you have raw HTML already and want to avoid re-fetching.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Pages behind authentication or paywalls may return incomplete or empty content
- Very large HTML payloads may exceed processing limits
- max_tokens set too low may produce truncated or unusable output
- BM25 query with no matching content may return minimal or empty excerpt
- Payment failure (HTTP 402) if x402 micropayment is not properly configured

## How this service works

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

## Output

Returns a JSON object containing the distilled content (Markdown text, structured JSON, skeleton headings, or BM25-ranked excerpt depending on mode), along with ROI proof metrics (raw token count, distilled token count, tokens saved, compression ratio, estimated LLM cost saved), cache status (HIT/MISS), and billing details.
