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 agentdiet-dev-agentdiet-rag-token-diet-web-url-distiller-0f49fdbe
```

Example prompt: Distill https://stripe.com/docs/payments into compact Markdown and keep it under 500 tokens, focusing on the query 'payment intents' using budget mode.

## When to prefer this

Choose this endpoint when you need to feed live web content into an LLM or RAG pipeline but must control token consumption precisely. It is ideal when a webpage is too verbose to include raw in a prompt, when you need BM25-focused extraction to surface only query-relevant content, or when you want structured tables/metadata extracted from HTML rather than prose. Prefer it over generic scrapers when token budget and LLM cost savings are explicit concerns.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Missing required 'url' parameter causes a 400-level error
- mode=budget without a query or max_tokens may produce unfiltered output
- Raw HTML too large may exceed processing limits
- Payment failure via x402 returns HTTP 402 before distillation occurs
- URL pointing to non-HTML content (PDF, binary) may yield empty or malformed 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://agentdiet.dev/v1/rag-token-diet)

## Output

Returns a 'data' object containing the distilled content in the requested format (Markdown, structured JSON, skeleton, or BM25-focused excerpt), plus an roi_proof object showing raw token count, distilled token count, tokens saved, compression ratio percentage, LLM cost saved in USD, and ROI multiplier. Also includes optional cache status (HIT/MISS) and billing details.
