## 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-db89f193
```

Example prompt: Check the DEX whale orderflow and accumulation signals for AERO right now — is smart money buying or selling on Base, and what's the 1h vs 24h buy/sell ratio?

## When to prefer this

Choose this endpoint when you need real-time on-chain DEX whale flow analysis specifically for Base and Solana tokens — particularly when you want to detect large-wallet accumulation signals or buy/sell imbalances before making a trade or investment decision. It is distinct from generic price APIs because it focuses on orderflow momentum and whale behavior rather than just price/volume.

## Known failure modes

- Unknown or unsupported token symbol returns empty or error response
- Contract address not found on Base or Solana returns no data
- Stale or illiquid token with no recent DEX activity may return zero or null metrics
- Missing required 'symbol' parameter returns a validation error
- Rate limiting or payment failure (HTTP 402) blocks the request

## 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/smart-money-flow)

## Output

Returns a JSON object containing real-time DEX orderflow data for the requested token, including 1h and 24h buy/sell pressure ratios, whale accumulation signals, and liquidity velocity metrics across Base and Solana DEX pools.
