## 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 polymarket-odds-agentdiet-dev-base-solana-dex-whale-orderflow-e0763e3d
```

Example prompt: Can you scan DEX whale orderflow for SOL right now — I want to see the 1h and 24h buy/sell ratios and whether whales are accumulating or distributing on Base and Solana?

## When to prefer this

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

## Known failure modes

- Missing or invalid symbol parameter returns an error
- Token not found or not tracked on Base/Solana returns empty or null data
- Network timeouts if on-chain data feeds are delayed
- Unsupported token contract address may return no signals
- Payment required (HTTP 402) if x402 micropayment header is absent or insufficient

## 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://polymarket-odds.agentdiet.dev/v1/institutional-flow)

## Output

Returns buy/sell orderflow ratios over 1h and 24h windows, whale accumulation signals indicating whether large wallets are net buyers or sellers, and liquidity velocity metrics — all scoped to DEX activity across Base and Solana for the requested token.
