Robinhood Chain buyer bursts from the last 1-240 minutes, on every ETH-quoted Uniswap v4 and v3 pool created on the chain in the last 24 h. Each burst carries net ETH inflow, buy and sell swaps, scripted vs spread buying, pool age and a rug check (who held the pool's liquidity at the signal); outcomes are scored 30 minutes after the signal. Data rewritten every 20 s (<= 30 s behind the chain); data older than 120 s is refused with a 503 and not charged. Costs $0.01 USDC per call (x402).
