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 llms-generator-agentdiet-dev-web-url-to-markdown-distiller-with-bm25-7ef89a1f
```

Example prompt: Can you fetch https://stripe.com/docs/payments and distill it into clean markdown, keeping it under 2000 tokens and focusing on the payment intents section?

## When to prefer this

Choose this endpoint when you need to reduce the token cost of ingesting web content into an LLM context — especially when working with documentation pages, landing pages, or any URL where you need BM25-focused relevance filtering or a strict token budget. It is superior to raw HTML fetching when token efficiency matters, and preferable over generic scrapers when you need structured JSON tables, skeleton outlines, or Markdown output with compression metrics included.

## Known failure modes

- URL is unreachable or returns a non-200 response — endpoint may return an error status
- Raw HTML input is too large or malformed — distillation may fail or truncate
- mode=budget used without a query parameter — BM25 filtering cannot proceed
- max_tokens set below 20 — rejected by schema validation
- Target URL blocks scrapers/bots — content may be empty or incomplete
- Payment not provided or insufficient — HTTP 402 response blocking execution

## Output

Returns a JSON object containing the distilled content (Markdown, structured JSON, skeleton, or BM25 excerpt) in `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), and billing details including fee_charged_usd.
