## 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 token-intel-agentdiet-dev-webpage-distiller-with-bm25-budget-control-d76272ab
```

Example prompt: Can you fetch https://stripe.com/docs/api/charges and distill it into markdown, keeping it under 800 tokens and focusing on the query 'charge creation parameters'?

## When to prefer this

Choose this endpoint when you need to reduce the token footprint of web content before feeding it to an LLM, especially when working with documentation, product pages, or any lengthy HTML. The BM25 budget mode is uniquely useful when you have a specific query and a hard token ceiling — it retrieves only the most relevant passages. Prefer this over generic scrapers when token cost and compression ratio matter, or when you need structured output (tables, metadata) rather than raw HTML.

## Known failure modes

- URL is unreachable or returns non-2xx HTTP status — endpoint may return an error status
- HTML is malformed or too large to process within limits
- max_tokens set below 20 — rejected by schema validation
- BM25 query provided without mode=budget — query may be ignored
- Paywalled or JavaScript-heavy pages may not yield useful content
- Payment not provided or insufficient — HTTP 402 returned requiring x402 USDC payment

## How this service works

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

## Output

Returns a data object containing the distilled content (markdown text, structured JSON tables/metadata, skeleton outline, or BM25-focused excerpt depending on mode), plus an roi_proof block showing raw vs. distilled token counts, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and a ROI multiplier. Also includes cache status (HIT/MISS), cache key, latency, and billing details.
