## 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 hn-pulse-agentdiet-dev-base-solana-dex-whale-orderflow-accumulation-791e0af1
```

Example prompt: Check whale orderflow on AERO right now — I want to see the 1h and 24h buy/sell ratios and whether big wallets are accumulating or distributing on Base and Solana DEXes.

## When to prefer this

Choose this endpoint when you need real-time on-chain DEX whale activity, large-wallet accumulation signals, or buy/sell pressure analytics specifically for tokens on Base or Solana — especially when timing a trade or detecting early momentum shifts driven by institutional or whale wallets.

## Known failure modes

- Missing or invalid symbol parameter returns a 400 error
- Unrecognized token symbol or contract address returns empty or null data
- Payment not completed via x402 results in a 402 Payment Required response
- Temporary data gaps for low-liquidity tokens may yield incomplete orderflow metrics
- Rate limiting or network latency may delay real-time data freshness

## 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://hn-pulse.agentdiet.dev/v1/whale-alerts)

## Output

Returns structured data including 1h and 24h DEX buy/sell orderflow ratios, whale accumulation or distribution signals, and liquidity velocity metrics for the queried token across Base and Solana decentralized exchanges
