## 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 defi-yield-agentdiet-dev-web-url-markdown-distiller-with-bm25-budget-27878e23
```

Example prompt: Distill https://stripe.com/docs/payments into compact markdown, use budget mode with a max of 2000 tokens and focus the BM25 query on 'payment intents API'.

## When to prefer this

Choose this endpoint when an AI agent needs to read a web page but must minimize token consumption before passing content to an LLM. It is ideal for agentic pipelines that fetch external URLs, research tasks with tight context windows, or any workflow where LLM cost per page matters. The BM25 budget mode makes it uniquely suited when you have a specific query focus and a strict token ceiling — unlike generic scrapers that return full raw HTML or uncompressed markdown.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Target page blocks crawlers or requires JavaScript rendering, yielding incomplete content
- max_tokens set too low may truncate critical content
- BM25 query with no matching terms in budget mode may return minimal output
- Raw HTML input that is malformed may produce poor distillation quality
- Rate limiting or payment failure via x402 may block the request

## How this service works

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

## Output

Returns a JSON object containing the distilled content in the requested mode (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-focused excerpt), plus an roi_proof block with raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, and llm_cost_saved_usd. Also includes cache status (HIT/MISS) and billing details.
