## 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 email-verify-agentdiet-dev-web-url-distiller-with-bm25-budget-control-3967bbad
```

Example prompt: Fetch the page at https://stripe.com/docs/payments and distill it into compact markdown — keep it under 500 tokens and focus on anything related to payment intents.

## When to prefer this

Choose this endpoint when you need to reduce the token footprint of web content before passing it to an LLM, especially when working within tight context windows or cost budgets. It is particularly valuable when you need BM25-focused extraction (mode=budget) to pull only the most query-relevant passages from a long page, or when you want structured JSON tables and metadata rather than raw HTML. Prefer it over generic scrapers when token efficiency and LLM-readiness are primary concerns.

## Known failure modes

- Invalid or unreachable URL returns an error status
- URL behind authentication or paywalls may return empty or partial content
- mode=budget without a query or max_tokens may produce unexpected output
- Very large pages may be truncated even without a token budget
- Raw HTML injection via the html parameter may fail if malformed
- Rate limiting or payment failure via x402 returns 402 status

## How this service works

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

## Output

Returns a JSON object containing distilled page content in the requested format (Markdown, structured JSON tables, skeleton outline, or BM25-focused excerpt), along with ROI proof metadata showing raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD. Also includes cache status and billing information.
