## 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 mesh-agentdiet-dev-web-content-distiller-with-bm25-budget-control-22666326 -d '<json body>'
```

Example prompt: Distill https://stripe.com/docs/payments into clean markdown and keep it under 800 tokens, focused on the query 'payment intents API' using budget mode.

## When to prefer this

Choose this endpoint when you need to reduce token consumption before passing web content to an LLM, especially when working with long documentation pages, noisy HTML, or tight context budgets. The BM25 budget mode is uniquely powerful for query-focused extraction with a strict token ceiling — no other generic scraper offers this. Prefer this over raw fetch-and-parse when token cost and LLM context limits are the primary concern.

## Known failure modes

- Invalid or unreachable URL returns a fetch error
- HTML too large or malformed may cause parsing failures
- mode=budget requires both query and max_tokens — missing either may produce incomplete results
- Rate limiting or payment failures (HTTP 402) if USDC balance is insufficient
- Timeout on slow-loading pages or pages behind authentication walls

## How this service works

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

## Output

Returns a distilled version of the webpage or HTML in the requested format (Markdown, structured JSON, skeleton, or BM25-focused excerpt), along with ROI proof metrics including raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and an ROI multiplier. Also includes cache status (HIT/MISS) and billing details.
