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-compressor-with-bm25-0f44fe0f
```

Example prompt: Distill https://stripe.com/docs/payments into compact markdown using budget mode, focused on 'payment intents', and keep it under 500 tokens so I can fit it in my context window.

## When to prefer this

Choose this endpoint when you need to feed web page content into an LLM but want to minimize token consumption, especially with the 'budget' mode and BM25 query focusing. It is ideal over generic scrapers when you need quantified ROI proof of compression savings, need multiple output formats (markdown, structured, skeleton), or are working within strict context-window constraints. Particularly suited for agent pipelines that need to process many URLs cost-efficiently.

## Known failure modes

- URL is unreachable or returns non-200 status — endpoint may return an error status
- Raw HTML exceeds processing limits — may fail or truncate silently
- mode=budget used without a query parameter — BM25 ranking may be unfocused
- max_tokens set below 20 — rejected by schema validation
- Invalid or malformed URL — returns error status
- Rate limiting or payment failure via x402 — HTTP 402 returned

## 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-compress)

## Output

Returns a 'data' object containing the distilled content (markdown, structured JSON tables/metadata, skeleton outline, or BM25-focused excerpt), along with an 'roi_proof' block showing raw vs distilled token counts, tokens saved, compression ratio percentage, LLM cost saved in USD, and ROI multiplier. Also includes optional cache status (HIT/MISS) and billing details.
