How this service works
Self-hosted AI API gateway. Expensive endpoints require an x402 micropayment (USDC on Base) before executing.
Output
Returns a JSON object containing the converted currency value from AOA to UGX, representing how much of the target currency (Ugandan Shilling) the input amount corresponds to at the current exchange rate.
Example use cases
Cross-border African trade pricing
“I'm invoicing a Ugandan client in UGX but my costs are in AOA — can you convert 250000 Angolan Kwanza to Ugandan Shillings so I can figure out the right price?”
Travel budget estimation Uganda
“I'm heading to Uganda from Angola and have 150000 AOA to spend — how much is that in Ugandan Shillings?”
Remittance amount verification
“I want to send money to Uganda and I have 80000 AOA — convert that to UGX so I know how much the recipient will get.”

Endpoint
POSThttps://api.fastapi.online/f/fx/aoa/ugx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need AOA-to-UGX currency conversion with minimal per-call cost via x402 USDC micropayment on Base, and are operating within an x402-compatible agent wallet infrastructure. Prefer this over general FX APIs when you want a self-hosted, pay-per-use gateway rather than subscription-based services.
Side effects
- Payment not attached or insufficient USDC micropayment returns HTTP 402 Payment Required
- Invalid or non-numeric amount value returns validation error
- Downstream exchange rate provider unavailable returns 5xx error
- Amount of 0 or negative number may return error or zero result
