How this service works
Self-hosted AI API gateway. Expensive endpoints require an x402 micropayment (USDC on Base) before executing.
Output
Returns a conversion result object indicating the value of the specified ARS amount in the target currency, based on current exchange rates.
Example use cases
Travel budget in pesos
“I'm traveling to Argentina and have $200 USD — how many Argentine pesos would that be? Actually, can you tell me what 10000 ARS is worth in USD?”
Invoice amount reconciliation
“I received an invoice for 75000 ARS — can you convert that to USD so I know how much to record in our books?”
Quick peso spot check
“What's 1 Argentine peso worth right now in USD?”
