How this service works
309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.
Output
A JSON response with a list of supported foreign exchange currency symbols and codes that can be used to query exchange rates or construct FX pairs on this platform.
Example use cases
Validate currency code before FX query
“Before I request the EUR/USD exchange rate, can you check what FX symbols are supported so I know I'm using the right currency codes?”
Build forex pair selector UI
“Fetch me all available FX currency symbols so I can populate the currency dropdown in my exchange rate comparison tool.”
Audit supported currencies for reporting
“Can you get me the complete list of forex symbols this service supports so I can cross-check which currencies I can include in my financial report?”
