## 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 x402-audit-agentdiet-dev-web-url-distiller-with-bm25-budget-control-b7e76424
```

Example prompt: Distill https://stripe.com/docs/payments into compact markdown, keeping it under 1000 tokens — I want a clean, compressed version I can feed directly into my context window.

## 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, articles, or HTML payloads that would exceed context limits or inflate costs. Prefer it over raw web scraping when you need the output to be immediately LLM-ready (markdown or structured JSON) rather than raw HTML. The BM25 budget mode is especially useful when you have a specific question and want only the most relevant excerpts from a page within a strict token ceiling.

## Known failure modes

- Invalid or unreachable URL returns an error status
- max_tokens below minimum (20) causes validation error
- BM25 query missing when mode=budget may return unfiltered budget result
- Raw HTML too large may cause timeout or partial distillation
- Payment failure via x402 returns HTTP 402 without processing

## How this service works

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

## Output

Returns a JSON object containing the distilled content (markdown, structured tables/metadata, skeleton outline, or BM25 excerpt depending on mode), plus ROI proof metrics showing raw vs distilled token counts, compression ratio, tokens saved, and estimated LLM cost saved in USD. Also includes cache hit/miss status and billing details.
