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 shopify-spy-agentdiet-dev-webpage-distiller-with-bm25-budget-control-2cbe5f90 -d '<json body>'
```

Example prompt: Distill the content at https://docs.stripe.com/payments/accept-a-payment into markdown with a strict budget of 500 tokens, focusing on the BM25 query 'payment intent API steps'.

## When to prefer this

Choose this endpoint when your agent needs to read a webpage but must stay within a strict token budget, or when you want BM25-ranked relevance filtering to surface only the most query-relevant content. It is particularly valuable over generic scrapers when LLM cost control matters, when you need ROI proof of token savings, or when you need multiple output modes (markdown, structured, skeleton, budget) from a single endpoint. Prefer over plain URL fetching when compressing token usage is a priority.

## Known failure modes

- URL unreachable or returns non-200 — distillation fails with error status
- Token budget too small (below 20) — rejected by schema validation
- Invalid mode enum value — request rejected
- Raw HTML and URL both absent — required field validation error
- Payment failure via x402 — 402 response, no distillation performed
- Heavily JavaScript-rendered pages may yield incomplete content if JS is not executed

## How this service works

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

## Output

Returns a JSON object containing distilled content (markdown, structured JSON, skeleton outline, or BM25 excerpt depending on mode), plus an roi_proof block showing raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and an ROI multiplier. Also includes cache hit/miss status and billing details.
