# Web URL DOM Distiller (BM25 Budget Mode)

> Web URL DOM Distiller (BM25 Budget Mode) is a paid API for AI agents from whale-momentum.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches a URL or raw HTML and distills it into compact, agent-ready tokens using Markdown, structured, skeleton, or BM25-focused budget modes

## 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 whale-momentum-agentdiet-dev-web-url-dom-distiller-bm25-budget-mode-d1b8cfa5
```

Example prompt: Can you distill https://stripe.com/docs/payments into clean Markdown and keep it under 1000 tokens, focusing on payment intents?

## When to prefer this

Choose this endpoint when you need to feed web page content into an LLM context and want to minimize token usage and cost. It is especially valuable when the target page is large, noisy, or HTML-heavy and you need clean Markdown, structured tables, or a BM25-ranked excerpt relevant to a specific query. Prefer it over generic scraping tools when token budget control and compression ROI measurement matter, or when working within strict LLM context window limits.

## Known failure modes

- URL is unreachable or returns non-200 HTTP status — endpoint may return an error status
- Raw HTML is malformed or too large to process within budget constraints
- mode=budget used without a query parameter — BM25 ranking has no focus term
- max_tokens set below 20 — rejected by schema validation
- Target site blocks automated fetching (bot protection, Cloudflare) — returns empty or partial content
- Payment failure via x402 — call blocked before execution

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://whale-momentum.agentdiet.dev/v1/dom-stripper)

## Output

Returns a 'data' object containing the distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), plus an ROI proof object showing raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and a compression ROI multiplier. Also includes cache hit/miss status and billing details.
