# RAG Token Diet – Web URL Distiller

> RAG Token Diet – Web URL Distiller is a paid API for AI agents from shopify-intel.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches a URL (or accepts raw HTML) and compresses it into compact, agent-ready Markdown, structured JSON, a skeleton outline, or a BM25-focused budget excerpt within a strict token ceiling

## 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 shopify-intel-agentdiet-dev-rag-token-diet-web-url-distiller-ec05ca8f
```

Example prompt: Pull the content from https://docs.stripe.com/payments/accept-a-payment and compress it into markdown mode, keeping it under 1500 tokens so I can use it in my pipeline without burning through my context window.

## When to prefer this

Choose this endpoint when you need to feed web content into an LLM or RAG pipeline but must stay within a token budget — particularly when the raw page HTML would be prohibitively large. It is especially useful for agent workflows that repeatedly fetch and process web pages, where per-call token savings translate directly into reduced LLM costs. Prefer it over generic scrapers when you need built-in BM25 relevance filtering (mode=budget) to focus on a specific query, or when you want structured JSON tables or skeleton outlines rather than raw HTML.

## Known failure modes

- URL is unreachable or returns non-200 (fetch error, page unavailable)
- HTML is malformed or empty resulting in near-zero distilled output
- mode=budget used without providing a query or max_tokens (degraded output)
- max_tokens set too low (below 20) triggering validation error
- Payment not included or insufficient funds via x402 protocol (402 response)
- URL behind authentication or paywalls that block fetching
- Oversized raw HTML payload exceeding server limits

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://shopify-intel.agentdiet.dev/v1/rag-token-diet)

## Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked budget excerpt), an 'roi_proof' object showing raw vs distilled token counts, compression ratio percentage, tokens saved, and estimated LLM cost saved in USD, plus optional cache hit/miss metadata and billing details.
