## 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 defi-yield-agentdiet-dev-webpage-distiller-with-bm25-budget-control-d797d031 -d '<json body>'
```

Example prompt: Fetch and distill https://docs.stripe.com/payments/payment-intents into clean markdown using budget mode, focusing on 'payment intent lifecycle' and keeping it under 2000 tokens.

## When to prefer this

Choose this endpoint when you need to reduce LLM token costs by compressing webpage content before passing it to a model, especially when working with documentation sites, long articles, or product pages. Particularly valuable in budget mode when you have a strict token ceiling and want BM25-focused relevance filtering. Prefer over generic scrapers when you need built-in token savings metrics and multiple output modes (markdown, structured, skeleton).

## Known failure modes

- Invalid or unreachable URL returns fetch error
- HTML too large may exceed processing limits
- BM25 budget mode without a query defaults or errors
- Token budget below minimum (20) rejected with validation error
- Rate limiting or payment failure blocks execution
- Paywalled or bot-protected pages may return incomplete content

## How this service works

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

## Output

Returns a data object containing the distilled webpage content in the requested format (Markdown, structured JSON, skeleton, or BM25 excerpt), along with an roi_proof object showing raw vs distilled token counts, tokens saved, compression ratio percentage, LLM cost saved in USD, and ROI multiplier. Also includes cache status (HIT/MISS) and billing details.
