Travel budget currency check
“I'm traveling to Japan next month with 2000 USD — what's today's exchange rate from USD to JPY and how many yen will I get?”
Cross-border payment validation
“Before I send a wire transfer, can you tell me the current mid-market rate from GBP to USD for 750 pounds and what that converts to in dollars?”
Technical details
Endpoint
POSThttps://landingen24h.com/api/x402/fx/rate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a reliable, ECB-sourced mid-market daily reference rate for currency conversion between any two ISO 4217 currencies. It is ideal for informational conversions, invoicing, budgeting, and pre-payment checks. It is not suitable for live spot trading rates or real-time tick data. It returns blended central-bank reference rates, making it appropriate for financial transparency and reporting use cases rather than active FX trading.
Side effects
- Invalid or unsupported ISO 4217 currency code returns an error
- Same currency for 'from' and 'to' may return rate of 1
- Negative or zero amount may be rejected by minimum validation
- Service unavailability from upstream Frankfurter data source
- Malformed request body missing required fields
