# Web URL to Markdown Distiller with BM25 Budget Control

> Web URL to 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 (last checked 2026-10-21).

Fetches a web URL (or accepts raw HTML) and distills it into compact, agent-ready Markdown, structured JSON, skeleton outline, or BM25-ranked token-budgeted excerpts

## 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-to-markdown-distiller-with-bm25-0bf90a68
```

Example prompt: Fetch https://stripe.com/docs/payments/accept-a-payment and distill it into compact markdown using budget mode focused on 'payment intent setup', keeping it under 500 tokens.

## When to prefer this

Choose this endpoint when an AI agent needs to ingest web content efficiently without blowing its token budget — especially when the raw HTML would be too verbose for direct LLM consumption. It is ideal for agentic pipelines that need to read documentation, extract structured data from web pages, or focus on specific topics within a large page using BM25 ranking. Prefer it over generic scraping tools when token cost reduction and ROI measurement matter.

## Known failure modes

- Invalid or unreachable URL returns a fetch error with status != ok
- max_tokens below minimum (20) causes a validation error
- BM25 query provided without mode=budget may be ignored
- Raw HTML too large may exceed processing limits
- Paywalled or bot-blocked pages may return empty or partial content
- Missing required 'url' parameter returns a 422 validation error
- x402 payment failure returns HTTP 402 with payment details

## 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/html-to-markdown)

## Output

Returns a distilled payload in the requested mode (Markdown text, structured JSON with tables/metadata, a skeleton outline, or a BM25-ranked excerpt), along with an ROI proof object showing raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and optional billing and cache metadata.
