Coil Top-Volume Scores
GET https://coil.trade/api/board/top-volume
Listed in Coinbase x402 Bazaar
Scores for the most-traded US stocks — the liquid mega-caps agents actually trade. One read returns the top names by 20-day average dollar volume in every S&P 500 sector, each scored: opportunity 0-100 plus board percentile, entry state (READY / SETUP / WAIT / CHASE / FALLING), hold strength, leadership flag, and the dollar-volume figure that ranked it. High-liquidity names only, no illiquid tail. Refreshed ~5 min in market hours. Research, not advice.
