## 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 preflight-agentdiet-dev-base-solana-dex-whale-orderflow-accumulation-1f046863
```

Example prompt: Check the current whale orderflow and accumulation signals for AERO on Base and Solana DEXes — I want to see the 1h and 24h buy/sell ratios and whether smart money is moving in.

## When to prefer this

Use this endpoint when you need real-time on-chain DEX intelligence specifically about whale wallet behavior, smart money accumulation, and buy/sell pressure for tokens on Base or Solana — especially before executing a trade or monitoring a position for large-wallet signals. Prefer this over generic price APIs when the user wants to understand institutional or whale-level orderflow rather than just spot price.

## Known failure modes

- Unknown or unsupported token symbol returns empty or error response
- Contract address on unsupported chain returns no data
- Rate limiting or payment failure (HTTP 402) if x402 micropayment not attached
- Stale data if on-chain indexer is lagging
- Invalid symbol format (e.g. typo) returns no results

## 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://preflight.agentdiet.dev/v1/smart-money-flow)

## Output

Returns real-time DEX analytics for the specified token including 1-hour and 24-hour buy/sell orderflow ratios, whale accumulation signals indicating large wallet behavior, and liquidity velocity metrics across Base and Solana decentralized exchanges.
