## 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 x402broker-com-rag-token-diet-web-url-distiller-8dd4c8a0
```

Example prompt: Distill the content at https://stripe.com/docs/payments into compact markdown, keeping it under 800 tokens and focusing on payment flow details.

## When to prefer this

Choose this endpoint when you need to feed web content into an LLM context window efficiently and token count is a concern. It is especially valuable for RAG pipelines, agent workflows that browse documentation, or any scenario where you need to compress arbitrary web pages into structured, clean text with a measurable compression ratio. Prefer it over generic scrapers when you need BM25-focused relevance filtering, multiple distillation modes, or built-in token budget enforcement.

## Known failure modes

- Invalid or unreachable URL returns an error status
- URL blocked by robots.txt or requires authentication — content unavailable
- mode=budget without a query or max_tokens may produce unoptimized output
- Raw HTML too large may exceed processing limits
- Payment failure (402) if x402 payment is not properly configured

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://x402broker.com/v1/rag-token-diet)

## Output

Returns a JSON object containing distilled web content in the requested format (Markdown, structured JSON, skeleton, or BM25 budget excerpt), 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 cache status (HIT/MISS) and billing details.
