Use this when the question is whether an ST0x tokenized stock on Base trades above or below the real share: send a ticker (NVDA, wtAAPL, FGI) and get the premium/discount in basis points from the deepest USDC pool (live) and the last Raindex fill vs the exchange quote, corrected for the ERC-4626 wrapper rate, with market session, age of every leg, pool depth, any cross-issuer pool (wtNVDA vs Coinbase NVDAc), and a one-sentence read. Unknown ticker -> 404, no charge.
