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-intel-agentdiet-dev-web-url-distiller-with-bm25-budget-control-e0a88d2d
```

Example prompt: Fetch the page at https://stripe.com/docs/payments and distill it into compact markdown — use budget mode with a 2000 token ceiling and focus the BM25 query on 'payment intents'.

## When to prefer this

Choose this endpoint when an AI agent needs to read and compress web content to fit within context window limits, especially when token cost matters. Ideal for reading documentation pages, extracting structured data from product or pricing pages, or getting focused excerpts using BM25 relevance filtering. Prefer over generic scrapers when you need built-in token budgeting, ROI metrics, and multiple distillation modes in one call.

## Known failure modes

- URL is unreachable or returns non-200 status — endpoint may return an error status
- URL points to a paywalled or bot-blocked page — distillation may return empty or partial content
- max_tokens set below 20 — validation error returned
- BM25 query provided without mode=budget — query may be ignored
- Raw HTML is malformed — distillation may produce incomplete output
- Rate limit or payment failure — HTTP 402 returned requiring payment

## 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-intel.agentdiet.dev/v1/spa-markdown-reader)

## Output

Returns a distilled representation of the webpage in the requested mode: Markdown text, structured JSON tables/metadata, a skeleton outline of headings, or a BM25-focused excerpt within a strict token budget. Also includes ROI proof metrics (raw vs distilled token counts, compression ratio, tokens saved, estimated LLM cost saved) and optional cache status.
