# Web Distillation & BM25 Budget-Controlled Token Optimizer

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

Fetches a URL or processes raw HTML and distills it into compressed Markdown, structured JSON, a skeleton outline, or a BM25-ranked token-budget excerpt

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 domain-osint-agentdiet-dev-web-distillation-bm25-budget-controlled-511c6a94 -d '<json body>'
```

Example prompt: Fetch https://stripe.com/docs/payments/payment-intents and distill it into clean markdown using budget mode with a max of 500 tokens, focused on the query 'how to confirm a payment intent'.

## When to prefer this

Choose this endpoint when an AI agent needs to process web content within a strict token budget, reduce LLM API costs by compressing pages before sending to a model, or extract only query-relevant sections of a large webpage. Particularly valuable when processing documentation sites, news articles, or any HTML-heavy page where raw content would be too large for a context window. Prefer over generic scrapers when you need built-in BM25 relevance filtering and ROI metrics showing exactly how many tokens and dollars were saved.

## 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 produce minimal output
- max_tokens set too low for meaningful content extraction — result may be truncated
- BM25 query in budget mode finds no relevant sections — returns lowest-scoring content
- Payment not completed via x402 — request blocked before processing
- Rate limit or timeout fetching a slow target URL

## How this service works

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

## 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' object showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd. Also includes cache status (HIT/MISS) and billing details.
