Technical details
Endpoint
POSThttps://api.fastapi.online/f/fx/ars/bnd?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to convert Argentine Peso (ARS) to Brunei Dollar (BND) and are operating within an x402-compatible micropayment workflow on Base. Prefer this over general-purpose FX APIs if your agent stack already handles x402 payments, or if you want a pay-per-call model with no subscription overhead.
Side effects
- Payment not provided or insufficient — returns HTTP 402 requiring USDC micropayment on Base before execution
- Invalid or non-numeric amount — may return a 400 or error object
- Service unavailable — self-hosted endpoint may return 503 or timeout
- Stale exchange rate data — rate may not reflect real-time market conditions
