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-context-trimmer-distiller-fb44f96a
```

Example prompt: Fetch the Stripe documentation page at https://stripe.com/docs/api and distill it into clean markdown, keeping it under 2000 tokens and focusing on the authentication section.

## When to prefer this

Choose this endpoint when you need to feed web page content to an LLM but must stay within a token budget, reduce API costs, or extract only the most relevant sections. It is particularly valuable when working with long documentation pages, product pages, or articles where raw HTML would consume too much context. The BM25 budget mode is uniquely suited for query-focused extraction where only topically relevant content matters.

## Known failure modes

- Invalid or unreachable URL returns an error status
- HTML too large or malformed may cause incomplete distillation
- mode=budget without a query or max_tokens may fall back to defaults
- Rate limiting or paywalled target pages may return empty or partial content
- x402 payment failure prevents endpoint execution
- max_tokens below minimum (20) is rejected with validation error

## 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/context-trimmer)

## Output

Returns a 'data' object containing the distilled content in the requested format (Markdown, structured JSON, skeleton outline, or BM25-ranked excerpt), plus an 'roi_proof' object showing raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD. Also includes cache hit/miss status and billing details.
