## 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 defi-yield-agentdiet-dev-base-solana-dex-whale-orderflow-accumulation-84e0f25c
```

Example prompt: Check the DEX whale orderflow and smart money accumulation signals for AERO right now — I want to see the 1h and 24h buy/sell ratios and whether whales are accumulating or distributing.

## When to prefer this

Choose this endpoint when you need real-time smart-money and whale orderflow intelligence specifically on Base and Solana DEX markets, including 1h/24h buy/sell pressure ratios and accumulation signals. Prefer this over generic price feeds when the goal is to detect whale positioning or momentum shifts rather than just current price. Best suited for pre-trade decision support, token screening, or on-chain signal monitoring.

## Known failure modes

- Unknown or unsupported token symbol returns an error or empty result
- Contract address not found on Base or Solana returns no data
- Insufficient DEX liquidity for a token may produce incomplete orderflow ratios
- Rate limiting or payment failure (x402) if USDC micropayment is not fulfilled
- Network or upstream data provider outage returns a 5xx error

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

## Output

Returns real-time DEX orderflow data including 1h and 24h buy/sell ratios, whale accumulation signals indicating net smart-money positioning, and liquidity velocity metrics — all scoped to the requested token across Base and Solana DEX pools.
