## 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 agentdiet-dev-agentdiet-web-distill-bm25-budget-aware-url-html-scraper-314d4d50 -d '<json body>'
```

Example prompt: Scrape https://stripe.com/docs/api and distill it into a BM25-focused excerpt about payment intents, keeping it under 500 tokens so it fits cleanly into my prompt context.

## When to prefer this

Choose this endpoint when you need to feed web content into an LLM context window efficiently and cost-effectively — especially when token budget is a concern. The BM25 budget mode is uniquely valuable when you have a specific query and want only the most relevant passages from a page rather than the full text. Prefer it over generic scrapers when you need built-in compression ROI metrics, multiple distillation modes (markdown, structured, skeleton, budget), or when working within the agentdiet MCP/A2A ecosystem. It is particularly strong for documentation pages, research papers, and data-rich HTML where token savings matter.

## Known failure modes

- URL is unreachable or returns non-200 — fetch failure with error status
- HTML payload is empty or malformed — distillation returns minimal or empty content
- max_tokens set below minimum of 20 — validation error
- mode=budget used without a query field — missing required BM25 query error
- Payment/x402 auth failure — 402 response if payment is not properly attached
- Rate limiting or timeout on slow target pages — latency spike or timeout error

## How this service works

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

## Output

Returns a 'data' object containing the distilled content in the requested format (Markdown text, JSON tables/metadata, skeleton outline, or BM25-ranked excerpt), plus an 'roi_proof' block showing raw vs distilled token counts, compression ratio, tokens saved, and estimated LLM cost saved in USD. Optionally includes billing details and cache hit/miss status with latency.
