Choose this endpoint when you need a low-cost, cryptographically verifiable snapshot of perpetual futures market data (open interest, funding rate, mark price, directional signal) across top crypto assets; especially useful when auditability of the data source matters due to Ed25519 signing, and when integrating DeFi trading signals into automated workflows on Base.
