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 mesh-agentdiet-dev-html-to-markdown-distiller-with-bm25-budget-control-a73b1dd4 -d '<json body>'
```

Example prompt: Fetch https://stripe.com/docs/api and distill it into compact markdown using budget mode with 'payment intents' as my BM25 focus query and a strict ceiling of 2000 tokens.

## When to prefer this

Choose this endpoint when an AI agent needs to ingest live web content without blowing its context window budget — especially when a strict token ceiling is needed via BM25 budget mode. Prefer over generic scrapers when you need token savings telemetry (compression ratio, LLM cost saved) alongside the content, or when you need structured JSON tables or skeleton outlines rather than raw HTML. Best suited for agents that process documentation, research pages, or product listings and need to keep LLM costs low.

## Known failure modes

- URL is unreachable or returns non-200 — fetch failure error
- HTML is empty or unparseable — distillation returns empty or error status
- mode=budget used without a query field — BM25 ranking cannot execute
- max_tokens set below 20 — violates minimum constraint and returns validation error
- Payment not provided or insufficient — x402 payment required response
- Target site blocks automated fetching — returns fetch blocked or empty 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/html-to-markdown)

## Output

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