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 github-audit-agentdiet-dev-webpage-distiller-with-bm25-budget-control-9bdb4357 -d '<json body>'
```

Example prompt: Can you fetch https://stripe.com/docs/payments/accept-a-payment and distill it into clean markdown, keeping it under 2000 tokens and focused on 'payment intents setup'?

## When to prefer this

Choose this endpoint when you need to feed web content into an LLM but want to minimize token consumption and cost — especially when the target page is verbose or noisy. The BM25 budget mode is uniquely valuable when you have a specific query and a strict token ceiling. Prefer it over generic scrapers when you need compression ratio reporting and LLM cost savings proof. It also accepts raw HTML directly, making it useful when you've already fetched the page yourself.

## Known failure modes

- URL is unreachable or returns non-200 — fetch fails with error status
- HTML or URL is missing/empty — validation error on required `url` field
- mode=budget used without a `query` parameter — BM25 ranking cannot run
- max_tokens set below minimum of 20 — rejected by schema validation
- Target page is JavaScript-rendered SPA with no static HTML — distillation yields minimal content
- Rate limit or payment failure via x402 — 402 Payment Required response

## How this service works

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

## Output

Returns a JSON object containing: a `data` field with the distilled content (Markdown string, structured tables/metadata JSON, skeleton outline, or BM25-ranked excerpt depending on mode); an `roi_proof` object showing raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD; a `cache` object indicating cache HIT/MISS and latency; a `billing` object with fee charged; and a `status` field ('ok' on success).
