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 alpha-stream-agentdiet-dev-agentdiet-web-distiller-with-bm25-budget-06f5e814 -d '<json body>'
```

Example prompt: Distill the content at https://docs.stripe.com/payments into clean markdown, and keep it under 2000 tokens using BM25 budget mode focused on 'payment intents'.

## When to prefer this

Choose this endpoint when you need to reduce token consumption from web pages before feeding content to an LLM — especially when you have a strict token budget and a specific focus query (mode=budget with BM25 ranking). Prefer it over generic scrapers when you want ROI-quantified compression with multiple output modes (markdown, structured, skeleton). Ideal for agentic workflows where context window costs matter and content relevance must be maximized per token.

## Known failure modes

- URL unreachable or returns non-200: fetch failure with status error
- Invalid or empty URL provided: validation error
- mode=budget used without query parameter: missing BM25 focus query error
- max_tokens set below minimum of 20: schema validation rejection
- Raw HTML too large for processing: payload size exceeded
- Paywalled or bot-blocked pages: content extraction failure
- x402 payment not attached or insufficient: 402 Payment Required response

## How this service works

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

## Output

Returns a JSON object containing: distilled content in the requested format (Markdown, structured JSON, skeleton, or BM25 excerpt) under 'data'; an 'roi_proof' object showing raw token count, distilled token count, tokens saved, compression ratio percentage, ROI multiplier, and estimated LLM cost saved in USD; optional cache hit/miss status with latency; and billing details including fee charged.
