## 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 serp-extract-agentdiet-dev-base-solana-dex-whale-orderflow-002d3e08
```

Example prompt: Can you scan AERO for whale accumulation signals and show me the 1h and 24h buy/sell orderflow ratios on Base DEX right now?

## When to prefer this

Use this endpoint when you need real-time on-chain DEX orderflow intelligence specifically for Base EVM or Solana tokens, especially when whale accumulation signals and buy/sell pressure ratios are the primary signal you want. Prefer this over generic price APIs when directional orderflow momentum and large-wallet behavior are the focus.

## 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 resolved
- Stale data if DEX data source is temporarily unavailable
- Malformed symbol input may return validation 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://serp-extract.agentdiet.dev/v1/whale-tracker)

## Output

Returns structured data including real-time 1h and 24h DEX buy/sell orderflow ratios, whale accumulation signals, and liquidity velocity metrics for the requested token on Base and/or Solana networks.
