# Web URL to Agent-Ready Token Distiller (RAG Token Diet)

> Web URL to Agent-Ready Token Distiller (RAG Token Diet) is a paid API for AI agents from whale-momentum.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches a URL or raw HTML and distills it into compact, token-efficient content using BM25 budget control and multiple extraction modes.

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 whale-momentum-agentdiet-dev-web-url-to-agent-ready-token-distiller-920545e1
```

Example prompt: Can you distill https://stripe.com/docs/payments into compact markdown, staying under 800 tokens, and focus the BM25 budget on 'payment intents'?

## When to prefer this

Choose this endpoint when you need to reduce token overhead before feeding web content into an LLM — especially when working within strict context window budgets. It is preferable to raw fetch+truncation because it provides BM25-ranked relevance filtering, structured extraction modes, and quantified ROI metrics. Ideal for RAG pipelines, agent research tasks, and any workflow where web pages must be ingested cheaply and precisely.

## Known failure modes

- URL is unreachable or returns non-200 — distillation cannot proceed
- HTML payload is empty or malformed — structured/skeleton modes may return sparse output
- max_tokens set too low (below 20) — rejected by schema validation
- mode=budget used without a query — BM25 ranking has no focus signal
- Rate limiting or payment failure via x402 — 402 response with no content
- Target page is behind authentication or a CAPTCHA — fetch returns empty or login HTML

## How this service works

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

## Output

Returns a distilled version of the target webpage or HTML in the requested mode (markdown, structured JSON, skeleton outline, or BM25-focused budget excerpt), plus an roi_proof object showing raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and a cache status indicator.
