# RAG Token Diet – URL & HTML Distiller with BM25 Budget Control

> RAG Token Diet – URL & HTML Distiller with BM25 Budget Control is a paid API for AI agents from sec-intel.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-23).

Fetches a URL or accepts raw HTML and distills it into compressed Markdown, structured JSON, a skeleton outline, or a BM25-ranked budget excerpt capped by a strict token limit.

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 sec-intel-agentdiet-dev-rag-token-diet-url-html-distiller-with-bm25-0f58484e -d '<json body>'
```

Example prompt: Pull the content from https://stripe.com/docs/api and distill it down to at most 500 tokens using budget mode, focused on the query 'webhook event types', so I can fit it into my prompt without blowing my context window.

## When to prefer this

Choose this endpoint when you need to reduce the token footprint of web content before feeding it into an LLM, especially when working with large documentation pages, HTML dumps, or any URL where you want to control the output size precisely. Prefer it over generic scrapers when you need BM25-ranked relevance filtering (budget mode) or structured JSON extraction (structured mode) rather than a raw content dump. It is purpose-built for RAG pipelines and agentic workflows where LLM context and cost are constraints.

## Known failure modes

- URL is unreachable or returns a non-200 status — endpoint may return an error status
- HTML payload is empty or malformed — distillation may return minimal or empty data
- Token budget (max_tokens) set too low — may produce a very short or truncated excerpt
- BM25 query missing when mode=budget — query field required for meaningful budget excerpts
- Payment failure via x402 — call rejected if USDC payment cannot be processed
- Rate limiting or idempotency key collision — retry with a fresh Idempotency-Key UUID

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://sec-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 excerpt depending on mode), plus an 'roi_proof' block showing raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD. Also includes optional cache hit/miss status and billing details.
