Technical details
Endpoint
GEThttps://api.strale.io/x402/exchange-rateWhen to prefer
Choose this endpoint when you need an authoritative, ECB-sourced exchange rate with both the direct and inverse rate for any major currency pair. Prefer it over scraping or unofficial sources when accuracy and a known data provenance (ECB) matter. Use it for financial applications requiring a trusted, dated rate.
Side effects
- Invalid or unsupported ISO 4217 currency code returns an error
- Missing 'from' or 'to' query parameter results in a validation error
- ECB data unavailable or stale on non-business days may return previous rate with older date
- Payment failure (x402 protocol) if USDC balance is insufficient
