## 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 domain-osint-agentdiet-dev-web-url-markdown-distiller-with-bm25-7b575552
```

Example prompt: Distill the content at https://docs.stripe.com/api into compact markdown using budget mode, focused on 'payment intents', and keep it under 500 tokens.

## When to prefer this

Choose this endpoint when you need to feed web page content into an LLM but want to minimize token usage and cost. It is especially valuable when operating under strict context window constraints, when you need BM25-ranked relevance filtering to surface only query-relevant passages, or when you want structured/skeleton extraction rather than raw HTML. Prefer it over generic web scrapers when token efficiency and LLM-readiness are priorities.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Missing required 'url' parameter causes a 400-level error
- mode=budget without a 'query' parameter may produce unfocused results
- max_tokens below minimum of 20 is rejected
- Raw HTML too large may time out or exceed processing limits
- Payment not provided or insufficient triggers HTTP 402

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://domain-osint.agentdiet.dev/v1/markdown-distill)

## Output

Returns a 'data' object containing distilled content in the requested format (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-focused budget excerpt), plus an 'roi_proof' object showing raw vs distilled token counts, compression ratio, tokens saved, and estimated LLM cost savings. Optionally includes cache hit/miss status and billing details.
