Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 x402broker-com-webpage-distiller-with-bm25-budget-control-2faa938d -d '<json body>'
```

Example prompt: Fetch and distill https://docs.stripe.com/payments/payment-intents into clean markdown, and also give me a BM25-focused excerpt about webhook events with a max token budget of 500 tokens.

## When to prefer this

Choose this endpoint when an AI agent needs to consume webpage content within a tight token budget, wants BM25-ranked relevance filtering against a specific query, or needs structured/skeleton extraction rather than raw HTML. Especially valuable when LLM context costs matter and you want documented ROI proof of compression savings. Prefer over generic scrapers when you need token-aware distillation with cost accounting.

## Known failure modes

- URL unreachable or returns non-200 status — fetch failure error
- Invalid or malformed URL string — validation error
- HTML payload too large to process within limits
- BM25 budget mode used without a query parameter — missing required field error
- max_tokens below minimum of 20 — schema validation error
- Payment failure via x402 protocol — 402 response blocking execution
- Timeout fetching slow or unresponsive URLs

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://x402broker.com/v1/webpage-distiller)

## Output

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