How this service works
Self-hosted AI API gateway. Expensive endpoints require an x402 micropayment (USDC on Base) before executing.
Output
A JSON object containing the conversion result for the requested AOA-to-XPF amount; exact fields are unspecified but expected to include the converted value.
Example use cases
AOA to XPF travel budget check
“I'm travelling and need to know how much 5000 Angolan kwanza is in CFP francs — can you convert that for me using the x402 currency API?”
Automated FX rate lookup for invoicing
“Before I send this invoice, convert 1 AOA to XPF so I can set the current exchange rate in the document.”
Spot-check exotic currency pair
“What's the current value of 200 AOA in XPF? I need the exact converted amount, and it's fine to pay the micropayment for it.”

POSThttps://api.fastapi.online/f/fx/aoa/xpf?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need AOA-to-XPF currency conversion and are operating in an x402-enabled micropayment environment (paying $0.0002 USDC per call on Base). Prefer this over free converters when you need it integrated with x402 payment flows or the self-hosted gateway ecosystem.
Side effects
- 402 Payment Required if x402 micropayment is not provided or fails
- Invalid amount input returns validation error
- Network timeout if self-hosted gateway is unavailable
- Stale or missing exchange rate data returning an error or stale result
- Empty response object if internal computation fails
