## 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 mesh-agentdiet-dev-distill-url-or-html-to-markdown-with-bm25-budget-1c0af513 -d '<json body>'
```

Example prompt: Can you fetch https://stripe.com/docs/payments and distill it into clean markdown, keeping it under 2000 tokens using BM25 budget mode focused on 'payment intents'?

## When to prefer this

Choose this endpoint when you need to feed web content to an LLM and want to minimize token consumption while retaining the most relevant information. It is especially valuable when working with long documentation pages, research articles, or data-rich HTML where raw content would exceed context limits. The BM25 budget mode makes it uniquely suited for query-focused extraction with a hard token ceiling, which generic web scrapers and HTML-to-markdown converters do not offer.

## Known failure modes

- URL is unreachable or returns non-200 status — fetch fails with error
- HTML payload is empty or malformed — distillation produces minimal or empty output
- max_tokens set too low (below 20) — rejected by schema validation
- BM25 query not provided when mode=budget — may fall back to default behavior or error
- Rate limiting or payment failure via x402 — 402 response requiring payment
- Target URL blocks automated fetching (bot protection) — incomplete or blocked content

## How this service works

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

## Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown, structured JSON, skeleton, or BM25 excerpt depending on mode), plus an 'roi_proof' object showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, and llm_cost_saved_usd. Also includes cache hit/miss status and optional billing details.
