## 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 mcp-security-agentdiet-dev-agentdiet-web-url-distiller-2656fb42
```

Example prompt: Can you distill https://stripe.com/docs/payments into compact markdown, using budget mode focused on 'payment intents' with a max of 500 tokens, so I can use it as context without burning my token budget?

## When to prefer this

Choose this endpoint when an agent needs to ingest a live web page or HTML blob into its context window efficiently and cheaply. It is especially valuable when the raw page would exceed token budgets, making distillation a cost-saving necessity. Prefer it over raw fetch-and-pass when LLM costs matter, when the page is large or bloated, or when only a focused subset of the content is relevant to a query. The BM25 budget mode makes it uniquely suited for pinpointing relevant passages within a strict token ceiling.

## Known failure modes

- URL is unreachable or returns non-200 status — fetch failure error
- URL contains no parseable HTML content — empty or minimal output
- max_tokens is too low to capture meaningful content — may return truncated or empty excerpt
- mode=budget used without a query parameter — BM25 ranking has no focus signal
- Payment failure via x402 — endpoint returns 402 if agent wallet is unfunded
- Rate limiting or timeout on slow remote pages — latency exceeded

## How this service works

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

## Output

Returns a JSON object with a 'data' field containing distilled content (Markdown, structured JSON tables, skeleton outline, or BM25-focused excerpt depending on mode), plus an 'roi_proof' object showing raw vs distilled token counts, compression ratio, tokens saved, and estimated LLM cost saved in USD. Also includes cache status and billing details.
