# Web Distillation with BM25 Budget Control

> Web Distillation 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 clean Markdown, structured JSON, a skeleton outline, or a BM25-ranked token-budget excerpt for RAG pipelines

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-web-distillation-with-bm25-budget-control-3e8ba22c -d '<json body>'
```

Example prompt: Distill the page at https://stripe.com/docs/payments into clean markdown using budget mode, focused on the query 'payment intents API', and keep it under 500 tokens.

## When to prefer this

Choose this endpoint when you need to feed web content into an LLM or RAG pipeline and want to minimize token usage — especially when you have a specific query to focus on (BM25 budget mode) or need structured/skeleton output rather than raw HTML. Prefer it over generic scrapers when token cost and compression ratio matter, or when you need an ROI proof of how much context was saved. It is also ideal when you already have raw HTML and want to skip an extra fetch step.

## Known failure modes

- Missing required 'url' field returns a validation error
- Invalid or unreachable URL causes fetch failure
- mode=budget without a 'query' field may return unfiltered content
- max_tokens set below 20 fails schema validation
- Rate limiting or payment failure via x402 blocks execution
- HTML too large to process within time limits may time out

## 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-chunk)

## Output

Returns a JSON object containing the distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25 budget excerpt) under 'data', an ROI proof object showing raw vs. distilled token counts, compression ratio, tokens saved, and estimated LLM cost saved in USD, plus optional cache status (HIT/MISS) and billing details including fee charged.
