## 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 onchain-risk-agentdiet-dev-base-solana-dex-whale-orderflow-28ed52e3
```

Example prompt: Can you check the current whale orderflow and accumulation signals for AERO on Base — I want to see if big wallets are buying or selling right now and what the 1h and 24h buy/sell ratios look like?

## When to prefer this

Choose this endpoint when you need real-time whale-level orderflow intelligence specifically for tokens on Base or Solana DEXes — particularly when you want to detect accumulation patterns, smart money buying/selling pressure, or liquidity velocity shifts rather than just price or volume. Prefer this over generic DEX liquidity APIs when whale signal detection and orderflow ratio analysis are the primary goal.

## Known failure modes

- Unknown or unsupported token symbol returns an error or empty result
- Contract address on unsupported chain returns no data
- Rate limiting or payment failure (HTTP 402) if x402 USDC micropayment not provided
- Stale or missing liquidity data for low-volume tokens
- Invalid input format (empty symbol) rejected by schema validation

## How this service works

Tracks real-time 1h/24h DEX buy/sell orderflow ratios, whale accumulation signals, and liquidity velocity across Base and Solana. (Live x402 v2, IETF MPP & MCP endpoint at https://onchain-risk.agentdiet.dev/v1/base-dex-whales)
