# AgentDiet Semantic Distillation

> AgentDiet Semantic Distillation is a paid API for AI agents from rag-diet.agentdiet.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-22).

Strips 85-97% of HTML token bloat from a URL's content, returning semantically distilled text optimized for AI context windows

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-semantic-distillation-d3708713
```

Example prompt: Fetch the content at https://en.wikipedia.org/wiki/Large_language_model and distill it — strip all the HTML bloat so I can fit the key information into my context window without wasting tokens.

## When to prefer this

Choose this endpoint when you need to fetch a web URL and reduce its token footprint by 85-97% before feeding content into an LLM, RAG pipeline, or AI agent context window. It is particularly valuable when working with HTML-heavy pages where boilerplate navigation, scripts, and ads dominate raw content. Prefer this over generic web scrapers when token efficiency is the primary concern and you want a semantic signal rather than raw HTML.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Paywalled or JavaScript-rendered pages may yield incomplete distillation
- Rate limiting or payment failure (x402) if USDC payment not properly handled
- Unsupported content types (binary files, PDFs) may not distill correctly
- Very short pages may show low compression ratios with minimal benefit

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://rag-diet.agentdiet.dev settling in USDC on Base.

## Output

A JSON response containing the distilled semantic content of the requested URL, a status field ('ok'), and an roi_proof object showing the compression_ratio_pct (e.g. 91.4%) achieved — confirming how much token bloat was removed.
