Scans every US stock that also trades as a 24/7 synthetic perp and returns the gap: official (delayed) price, prev close, perp mark and oracle, funding APR, open interest, and computed `basis_percent` + `basis_vs_prev_close_percent` — the implied overnight move while the US market is shut. Widest dislocation first, plus a plain-English `reading`. `?limit=`, `?min_basis=`. From x402stock
