## 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-46458311
```

Example prompt: Can you check the current whale orderflow and accumulation signals for AERO on DEX — I want to see the 1h and 24h buy/sell ratios and whether big wallets are accumulating or distributing?

## When to prefer this

Choose this endpoint when you need real-time on-chain DEX whale orderflow intelligence specifically for tokens on Base or Solana, particularly when you want accumulation signals and buy/sell pressure ratios rather than just raw price or volume data. Prefer this over generic DEX APIs when the goal is detecting institutional or whale-level momentum shifts.

## Known failure modes

- Unknown or invalid token symbol returns empty or error response
- Contract address not found on Base or Solana returns no data
- Insufficient liquidity or very low volume tokens may return null signals
- Payment required (HTTP 402) if x402 micropayment not attached
- Rate limiting if too many calls made in quick succession

## 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/institutional-flow)

## Output

Returns an object containing real-time 1h and 24h DEX buy/sell orderflow ratios, whale accumulation signals (net buy or net sell pressure from large wallets), and liquidity velocity metrics for the requested token across Base and Solana DEX venues.
