Technical details
Endpoint
GEThttps://api.cortexcloud.org/x402/v1/fx/historyWhen to prefer
Choose this endpoint when you need historical FX rate data without committing to a subscription or API key — ideal for agents that make infrequent or one-off forex lookups and want to pay only per call in USDC on Base via x402. Best for lightweight, on-demand financial data needs rather than high-frequency or bulk data pipelines.
