# RAG Token Diet – BM25 Budget-Controlled Web Distillation

> RAG Token Diet – BM25 Budget-Controlled Web Distillation is a paid API for AI agents from token-intel.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-23).

Fetches and distills a URL or raw HTML into compressed Markdown, structured JSON, skeleton outline, or BM25-focused excerpt within a strict token budget

## 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 token-intel-agentdiet-dev-rag-token-diet-bm25-budget-controlled-web-0efd58af -d '<json body>'
```

Example prompt: Distill the content at https://stripe.com/docs/payments into clean Markdown using budget mode, focused on 'payment intents', and keep it under 500 tokens — I want to see how many tokens you saved me.

## When to prefer this

Choose this endpoint when you need to feed web content into an LLM pipeline and want to minimize token usage — especially when you have a specific query focus (BM25 mode) or a strict token budget ceiling. It is better than generic scrapers when token efficiency and cost savings are measurable requirements, and better than raw HTML fetchers when you need clean Markdown or structured output ready for downstream LLM consumption. Ideal for RAG pipelines, document Q&A systems, and any agent that repeatedly ingests live web content.

## Known failure modes

- Invalid or unreachable URL returns fetch error
- HTML payload too large may exceed processing limits
- mode=budget without a query may produce suboptimal BM25 ranking
- max_tokens set below minimum (20) returns validation error
- Paywalled or JavaScript-heavy pages may yield incomplete distillation
- Payment not included or invalid returns HTTP 402

## How this service works

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

## Output

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