# AgentDiet RAG-Diet Web Distillation API

> AgentDiet RAG-Diet Web Distillation API is a paid API for AI agents from alpha-stream.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-23).

Fetches a web URL and distills it into compact, token-efficient agent-ready content using multiple extraction modes (markdown, structured, skeleton, or BM25-focused budget)

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 alpha-stream-agentdiet-dev-agentdiet-rag-diet-web-distillation-api-56b81cb9
```

Example prompt: Distill https://docs.stripe.com/payments/quickstart into compact markdown and give me a token-efficient version I can use in my RAG pipeline — use budget mode with a max of 2000 tokens and focus the BM25 query on 'payment intents'.

## When to prefer this

Choose this endpoint when you need to pass web page content to an LLM but want to minimize token consumption and cost — especially for RAG pipelines, documentation ingestion, or any agent workflow where raw HTML or full-page markdown would be prohibitively large. It is uniquely valuable when you need BM25-focused budget extraction to retrieve only the most query-relevant tokens from a page, or when you want structured JSON tables automatically extracted. Prefer it over generic scraping APIs when token efficiency and LLM cost reduction are explicit goals.

## Known failure modes

- Invalid or unreachable URL returns an error status
- URL that blocks scraping bots may return empty or partial content
- mode=budget without a query parameter may degrade focus quality
- max_tokens set too low may truncate critical content
- Cursor-based pagination with invalid cursor returns an error
- Payment failure via x402 results in 402 response blocking execution
- Rate limiting may occur under high request volumes

## How this service works

Distill a web URL into compact agent-ready tokens (Live x402 v2, IETF MPP & MCP endpoint at https://alpha-stream.agentdiet.dev/v1/rag-diet)

## Output

Returns a distilled version of the target webpage in the requested format (markdown, structured JSON, skeleton outline, or BM25-focused budget excerpt), along with ROI proof metrics including raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and a ROI multiplier. Also includes optional cache status (HIT/MISS) and billing details.
