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 token-intel-agentdiet-dev-html-to-markdown-distiller-with-bm25-budget-7596544c -d '<json body>'
```

Example prompt: Fetch the page at https://stripe.com/docs/api and distill it into markdown with a strict budget of 2000 tokens, focusing on 'payment intents authentication' using BM25 mode so I only get the most relevant content.

## When to prefer this

Choose this endpoint when you need to reduce token consumption before feeding web content to an LLM, especially with strict context budgets. It is uniquely suited for agents that must process arbitrary URLs at scale while controlling costs, thanks to BM25 relevance filtering and ROI metrics. Prefer it over generic scrapers when you want distilled, LLM-ready output rather than raw HTML, and when you need structured or skeleton modes beyond plain text extraction.

## Known failure modes

- Invalid or unreachable URL returns fetch error
- Missing required 'url' field returns validation error
- mode=budget without a 'query' or 'max_tokens' may return unfiltered or oversized content
- Rate limiting or payment failure (HTTP 402) if USDC payment not completed
- Raw HTML too large may cause timeout or truncation
- Private/paywalled pages return empty or partial content
- Malformed HTML may produce garbled markdown output

## How this service works

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

## Output

Returns a JSON object containing: the distilled content (Markdown string, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt) under 'data'; an 'roi_proof' object with raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd; optional cache metadata (HIT/MISS, latency_ms); optional billing info; and a status field ('ok').
