# Web URL Distillation & RAG Token Compressor

> Web URL Distillation & RAG 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 accepts raw HTML and compresses it into compact, agent-ready tokens using BM25 budget control and multiple distillation 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 email-verify-agentdiet-dev-web-url-distillation-rag-token-compressor-15f654b2
```

Example prompt: Can you distill https://stripe.com/docs/payments into compact markdown, keeping it under 500 tokens and focusing on the query 'payment intents' using budget mode?

## When to prefer this

Choose this endpoint when you need to compress web content into a small token footprint before passing it to an LLM, especially in RAG or agentic pipelines where context window size and LLM cost are constraints. It is superior to raw web scraping when you need quantified compression metrics and BM25-guided relevance filtering. Prefer it over general-purpose scrapers when you need multiple output modes (markdown, structured, skeleton, budget) and built-in token budget enforcement.

## Known failure modes

- URL unreachable or returns non-200 status — fetch fails with error status
- max_tokens set below minimum of 20 — rejected with validation error
- BM25 query provided without mode=budget — query may be silently ignored
- Raw HTML too large to process within budget — may be truncated or error
- Payment not provided or insufficient — HTTP 402 payment required response
- Invalid URL format — validation error on required url parameter

## 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/rag-token-diet)

## Output

Returns a distilled data object containing Markdown, structured JSON tables/metadata, a skeleton outline, or a BM25-focused excerpt depending on mode; plus an ROI proof object showing raw vs distilled token counts, compression ratio percentage, tokens saved, estimated LLM cost saved in USD, and ROI multiplier; optionally includes billing details and cache hit/miss status with latency.
