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 cve-intel-agentdiet-dev-webpage-distiller-with-bm25-budget-control-9ff004e8 -d '<json body>'
```

Example prompt: Distill the content at https://docs.stripe.com/api into clean markdown, but cap it at 2000 tokens and focus the BM25 query on 'payment intents' so I only get the most relevant sections.

## When to prefer this

Choose this endpoint when an AI agent needs to read web content efficiently without exhausting LLM context windows or incurring high token costs. It is especially valuable when you have a specific query focus and want BM25-ranked excerpts under a strict token budget, or when you need structured JSON tables/metadata extracted from HTML rather than raw prose. Prefer it over generic scraping tools when token economy and ROI tracking matter, or when you already have raw HTML and want it cleaned into agent-ready format.

## Known failure modes

- URL is unreachable or returns non-200 status — endpoint may return an error status
- HTML payload is malformed or empty — distillation may fail or return minimal content
- max_tokens set too low (below 20) — rejected by schema validation
- BM25 query provided but mode is not 'budget' — query may be ignored
- Rate limiting or payment failure via x402 — request blocked
- Idempotency-Key collision on retries — may return cached prior result

## How this service works

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

## Output

Returns a 'data' object containing the distilled content in the requested mode (Markdown, structured JSON tables/metadata, skeleton outline, or BM25-ranked budget excerpt), plus 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.
