Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 hn-pulse-agentdiet-dev-base-solana-dex-whale-orderflow-accumulation-9d49bc5f
```

Example prompt: Check the current whale orderflow and accumulation signals for AERO on Base and Solana — show me the 1h and 24h buy/sell ratio and whether whales are accumulating.

## When to prefer this

Choose this endpoint when you need real-time on-chain DEX orderflow intelligence specifically for Base and Solana tokens, with a focus on whale-scale accumulation patterns and buy/sell pressure ratios. It is best suited for pre-trade momentum analysis, whale activity detection, and liquidity monitoring rather than general price feeds or CEX order book data.

## Known failure modes

- Missing or invalid 'symbol' parameter returns a validation error
- Unknown token symbol or contract address may return empty data or a not-found error
- Network or chain data unavailability may result in stale or partial orderflow data
- Payment failure (HTTP 402) if x402 payment is not provided or insufficient
- Rate limiting if the endpoint is called too frequently

## 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://hn-pulse.agentdiet.dev/v1/orderflow-radar)

## Output
