# Web URL Distiller & BM25 Token Compressor

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

Fetches a webpage or raw HTML and distills it into compact, agent-ready Markdown, structured JSON, skeleton outline, or BM25-focused budget excerpt with token savings metrics.

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 email-verify-agentdiet-dev-web-url-distiller-bm25-token-compressor-38d2c501
```

Example prompt: Grab the Stripe documentation page at https://stripe.com/docs/payments and distill it into compact markdown, keeping it under 2000 tokens using budget mode focused on the query 'payment intents'.

## When to prefer this

Choose this endpoint when an AI agent needs to read a webpage but must conserve LLM context tokens — especially for documentation, long articles, or competitor pages. The BM25 budget mode is uniquely useful when you only care about content relevant to a specific query. Prefer this over generic scrapers when you need quantified token savings metrics alongside the content.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Pages behind authentication or paywalls may return incomplete content
- Very large pages may hit internal fetch timeouts
- BM25 budget mode with max_tokens below 20 is rejected
- Raw HTML injection via 'html' parameter may fail if malformed
- Cache misses on first fetch may increase latency

## How this service works

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

## Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown text, structured JSON tables/metadata, skeleton heading outline, or BM25-focused excerpt depending on mode), plus an 'roi_proof' object detailing raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD. An optional 'cache' field indicates whether the result was served from cache and the latency.
