# AgentDiet DEX Context Compression Node

> AgentDiet DEX Context Compression Node is a paid API for AI agents from rag-diet.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Retrieves DEX (decentralized exchange) data after compressing AI agent context windows to reduce token usage by up to 91%

## Facts

- Endpoint: GET https://rag-diet.agentdiet.dev/v1/dex?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-22
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/agentdiet-dex-context-compression-node-3c8106cc
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_FmrUigW7UTi9lpqGTl423

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-dex-context-compression-node-3c8106cc
```

Example prompt: Use AgentDiet to compress my current context window and fetch the DEX data — I want to see the compression ratio I'm getting and the actual payload, paying via USDC on Base.

## When to prefer this

Choose this endpoint when your AI agent needs to reduce context window size before passing data to an LLM, especially in cost-sensitive pipelines where token usage is a bottleneck. It is particularly useful when you need a proof-of-compression (ROI proof) to verify savings. Prefer it over generic summarization tools when you need deterministic, metered, micropayment-gated compression with Base/USDC settlement via x402.

## Known failure modes

- Payment not settled — 402 response if USDC payment on Base is not confirmed
- Invalid token query parameter — endpoint may return error or empty data
- Unsupported HTTP method — only GET and POST are accepted per schema
- Schema validation failure — input object missing required 'type' or 'method' fields
- Service unavailability — node may be offline or unreachable at rag-diet.agentdiet.dev

## 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

Returns a JSON object with a 'data' field containing the compressed/distilled output, a 'status' field (e.g. 'ok'), and an 'roi_proof' object including a 'compression_ratio_pct' value (e.g. 91.4%) demonstrating how much the context was reduced.
