## 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 sec-intel-agentdiet-dev-web-url-markdown-distiller-with-bm25-budget-465f6f24
```

Example prompt: Can you distill https://stripe.com/docs/api into compact markdown using budget mode, focused on the query 'payment intents', keeping it under 500 tokens?

## When to prefer this

Choose this endpoint when an AI agent needs to read a webpage but must minimize token consumption — especially in RAG pipelines, agentic browsing, or multi-step research tasks where context window cost matters. It is preferable over raw HTML fetching or generic scrapers when you need clean markdown or structured output with quantified compression savings. The BM25 budget mode makes it uniquely suited for query-focused extraction where only a specific topic within a large page is relevant.

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status — distillation fails with an error status
- Paywalled or JavaScript-heavy pages may not render correctly and return incomplete content
- max_tokens set too low may produce heavily truncated output that omits critical content
- query parameter missing when mode=budget causes BM25 scoring to fall back to general distillation
- Payment not processed (x402 flow failure) results in no response or 402 error
- Invalid or malformed URL input causes immediate validation failure

## How this service works

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

## Output

Returns a JSON object containing the distilled content (markdown, structured JSON, skeleton, or BM25 budget excerpt), an ROI proof block showing raw vs distilled token counts, compression ratio, and estimated LLM cost saved, plus optional cache hit/miss status and billing details.
