Technical details
Endpoint
GEThttps://vibesprings.net/api/exchange/convertWhen to prefer
Use this endpoint when you need a precise, real-time fiat currency conversion with ECB-sourced rates, especially when both the converted amount and explicit forward/inverse rates are needed for financial auditing, invoicing, or cross-currency reporting. Prefer over generic free APIs when you need reliable, paid-tier rate accuracy and machine-readable inverse rates in a single call.
Side effects
- Unsupported currency ISO code returns an error — only 30+ supported fiat currencies are valid
- Missing required 'from' or 'to' query parameters returns a 400 bad request
- Invalid or non-numeric 'amount' string may return an error or default to 1
- ECB rate feed unavailability may cause stale or missing rate data
- Payment failure (x402) if USDC balance is insufficient
