## 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-96e9a815
```

Example prompt: Check the current whale orderflow and accumulation signals for AERO — is there significant buy pressure or institutional accumulation happening on DEX markets right now?

## When to prefer this

Choose this endpoint when you need real-time whale-level DEX orderflow intelligence specifically for Base and Solana tokens — particularly when you want accumulation signals, buy/sell pressure ratios, and liquidity velocity rather than just price or volume. Prefer this over generic DEX APIs when your use case involves detecting institutional or whale behavior patterns rather than simple OHLCV data.

## Known failure modes

- Invalid or unrecognized token symbol returns an error or empty result
- Contract address not found on Base or Solana returns no data
- Payment failure (HTTP 402) if x402 micropayment is not completed
- Rate limiting or timeout if the on-chain data source is slow
- Token with very low liquidity may return sparse or incomplete orderflow data

## 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/institutional-flow)

## Output

Returns structured on-chain data including 1h and 24h buy/sell orderflow ratios, whale accumulation indicators, liquidity velocity metrics, and momentum signals across Base and Solana DEX pools for the specified token or contract address.
