# Web URL Distillation & BM25 Token Budget API

> Web URL Distillation & BM25 Token Budget API is a paid API for AI agents from workflows.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches and distills any web URL (or raw HTML) into compact, agent-ready tokens using markdown, structured, skeleton, or BM25-budget extraction modes

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 workflows-agentdiet-dev-web-url-distillation-bm25-token-budget-api-03d5fff4
```

Example prompt: Fetch https://stripe.com/docs/payments and distill it into markdown, keeping it under 800 tokens using BM25 budget mode focused on 'payment intents'.

## When to prefer this

Choose this endpoint when an AI agent needs to ingest web content but must minimize token consumption and LLM costs. It is especially valuable when you have a strict token budget (use budget mode + max_tokens), want structured or outline extraction rather than raw HTML, or need BM25-ranked relevance filtering against a specific query. Prefer this over generic scraping tools when token ROI measurement and compression ratio reporting matter to your pipeline.

## Known failure modes

- URL is unreachable or returns non-200 — status error returned
- URL points to a PDF or binary file not parseable as HTML — may return empty or partial data
- max_tokens set too low (below 20) — validation error
- mode=budget used without a query parameter — BM25 focus may be undefined
- Payment not attached or insufficient — HTTP 402 returned before processing
- Rate limiting or timeout on slow remote URLs — partial or error 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://workflows.agentdiet.dev/v1/web-scrape)

## Output

Returns a JSON object with a 'data' field containing the distilled content (markdown text, structured 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, and estimated LLM cost saved in USD. Also includes cache hit/miss status and billing details.
