## 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 sec-intel-agentdiet-dev-spa-web-url-distiller-with-bm25-budget-control-9a26070d
```

Example prompt: Fetch the Stripe documentation page at https://stripe.com/docs/payments and distill it into compact markdown using budget mode with a focus query on 'payment intents' and a max of 500 tokens.

## When to prefer this

Choose this endpoint when an AI agent needs to read a webpage but must stay within a strict token budget — especially for documentation pages, landing pages, or any URL where raw HTML would be too large for an LLM context window. Prefer this over generic scrapers when token cost savings and compression ratio reporting matter, or when BM25-focused extraction on a specific subtopic is needed. Also suitable for SPA pages that require distillation rather than raw HTML passthrough.

## Known failure modes

- Invalid or unreachable URL returns fetch error
- SPA JavaScript-heavy pages may not render fully without a headless browser
- Token budget too low (below 20) returns validation error
- Missing required 'url' parameter returns 400 error
- BM25 query mode without a query string may return generic result
- Rate limiting or payment failure via x402 returns 402 Payment Required

## How this service works

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

## Output

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