## 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 x402-audit-agentdiet-dev-base-solana-dex-whale-orderflow-accumulation-3e706340
```

Example prompt: Can you check the current whale orderflow and accumulation signals for AERO on Base — specifically the 1h and 24h buy/sell ratios and whether there's any large institutional buying happening?

## When to prefer this

Choose this endpoint when you need real-time on-chain DEX orderflow intelligence specifically for Base EVM or Solana tokens, especially to detect whale accumulation patterns and buy/sell pressure ratios. Prefer this over generic price APIs when you need smart-money signals rather than just spot price or volume.

## Known failure modes

- Unknown or unsupported token symbol returns empty or error response
- Contract address on unsupported chain returns no data
- Payment not fulfilled (HTTP 402) blocks response
- Rate limiting or upstream DEX data provider unavailability causes timeout
- Newly launched tokens with insufficient liquidity may return incomplete signals

## 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://x402-audit.agentdiet.dev/v1/institutional-flow)

## Output

Returns structured data including 1h and 24h DEX buy/sell orderflow ratios, whale accumulation signals (e.g. large wallet net buy/sell indicators), and liquidity velocity metrics for the queried token across Base and Solana DEX pools.
