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 cve-intel-agentdiet-dev-web-url-html-distiller-with-bm25-budget-control-862d98f7 -d '<json body>'
```

Example prompt: Fetch the page at https://docs.stripe.com/payments/paymentintents and distill it into markdown, keeping it under 800 tokens and focused on the query 'payment confirmation flow' using budget mode.

## When to prefer this

Choose this endpoint when you need to feed live web content into an LLM pipeline and want to minimize token consumption with measurable ROI. It is especially valuable when you have a specific topic focus (use mode=budget with a BM25 query) or a hard token ceiling. Prefer it over generic scrapers when you need compression metrics (tokens saved, cost saved) alongside the content. Also ideal when you already have raw HTML and want to avoid a redundant fetch.

## Known failure modes

- URL unreachable or returns non-200 — fetch failure error
- HTML payload too large — may exceed processing limits
- max_tokens set below content minimum (must be ≥ 20) — validation error
- mode=budget used without providing a query — incomplete BM25 scoring
- Invalid URL format — schema validation error
- Payment/402 not settled — request blocked until x402 payment confirmed

## How this service works

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

## Output

Returns a 'data' object containing the distilled output (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), along with an 'roi_proof' object showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd. Optionally includes cache status (HIT/MISS) and billing details.
