## 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-web-url-html-distillation-with-bm25-budget-278f92b7
```

Example prompt: Distill the content at https://stripe.com/docs/payments into clean markdown, keeping it under 2000 tokens and focusing on the query 'payment intents API' using budget mode.

## When to prefer this

Choose this endpoint when an AI agent needs to read web content but must stay within a strict token budget or minimize LLM API costs. It is especially useful when fetching long documentation pages, news articles, or HTML-heavy sites where raw content would be too large for a context window. The BM25 budget mode makes it distinctly valuable when the agent needs topically focused extraction rather than the full page. Prefer it over generic scrapers when you need built-in token accounting and cost-savings telemetry.

## Known failure modes

- Invalid or unreachable URL returns an error status
- HTML fetch timeout for slow or blocked sites
- max_tokens below minimum (20) triggers validation error
- BM25 query mode without a query string may return unfiltered content
- Payment failure via x402 returns HTTP 402 with no content
- Malformed raw HTML in the 'html' field may produce degraded output

## 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/clean-html)

## Output

Returns a 'data' object containing the distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), alongside an roi_proof block showing raw vs distilled token counts, compression ratio, tokens saved, and estimated LLM cost saved in USD. Also includes cache status (HIT/MISS) and billing details.
