# AgentDiet Base DEX Whales Endpoint

> AgentDiet Base DEX Whales Endpoint 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).

Fetches whale activity data for decentralized exchanges on the Base blockchain, optionally filtered by token symbol.

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-base-dex-whales-endpoint-30303473
```

Example prompt: Can you pull the current whale activity on Base DEX for USDC — I want to see which big wallets are making large moves right now?

## When to prefer this

Choose this endpoint when you need on-chain whale activity data specifically for Base network DEXes, especially when operating in an agent context that benefits from compressed/distilled output (high compression ratio reduces token usage). Prefer over generic blockchain explorers when you want pre-filtered large-wallet DEX trade data without parsing raw chain data yourself. Best suited for agentic DeFi workflows that pay per call via x402/USDC micro-payments.

## Known failure modes

- Invalid or unsupported token symbol returns empty or error data
- Payment not settled in USDC on Base causes 402 rejection
- Malformed query parameters result in schema validation errors
- Network or node unavailability returns a non-200 status
- No whale activity found for the requested symbol returns empty data object

## 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 whale activity information for Base DEX, a 'status' field indicating success, and a 'roi_proof' object showing a compression_ratio_pct (e.g. 91.4%) indicating how much the context was compressed by the AgentDiet distillation layer.
