Endpoint
POSThttps://api.fastapi.online/f/fx/ars/aoa?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, low-cost ARS-to-AOA currency conversion via a micropayment-gated API and are already set up with x402/USDC on Base. Suitable for agents operating in fintech, cross-border payment, or FX-monitoring contexts where per-call pricing is acceptable and a self-hosted gateway is preferred over a centralized forex API.
Side effects
- Payment failure: x402 micropayment not completed or wallet lacks sufficient USDC on Base — returns 402 Payment Required
- Invalid input: non-numeric or missing amount field — returns validation error
- Rate data unavailable: exchange rate source offline — may return empty or error response
- Network timeout: self-hosted gateway unreachable — connection error or 503
