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 value of the specified AOA amount expressed in Zambian Kwacha (ZMW), likely including the converted amount and possibly the exchange rate applied.
Example use cases
Cross-border trade price check
“I'm sourcing goods from Angola and paying in Zambia — how much is 10000 AOA in ZMW today?”
Travel budget planning AOA to ZMW
“I'm traveling from Angola to Zambia next week and want to know how much 2500 Angolan Kwanza converts to in Zambian Kwacha.”
Single unit exchange rate lookup
“What is 1 AOA worth in ZMW right now? I just need the current exchange rate between Angolan Kwanza and Zambian Kwacha.”

Endpoint
POSThttps://api.fastapi.online/f/fx/aoa/zmw?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to convert AOA (Angolan Kwanza) to ZMW (Zambian Kwacha) and are operating in an x402-compatible payment environment using USDC on Base. The $0.0002 per-call cost is negligible for automated agents. Prefer this over general FX APIs if you are already integrated with the x402 payment protocol and need African currency pair coverage.
Side effects
- Payment not provided or insufficient USDC micropayment returns HTTP 402 Payment Required
- Invalid or non-numeric amount input returns a validation error
- Service unavailable if self-hosted backend is down
- Rate data may be stale if the underlying exchange rate feed is not refreshed
- Default amount of 1 used if amount field is omitted
