Technical details
Endpoint
POSThttps://x402.agentutility.ai/exchange-ratesWhen to prefer
Choose this endpoint when you need reliable, ECB-sourced exchange rates for 30+ major currency pairs with no commercial use restrictions, especially when historical rates by date or optional direct amount conversion in a single call is needed. Prefer over general web searches when structured, machine-readable rate data is required.
Side effects
- Unsupported or misspelled currency code returns an error
- Future dates are invalid — only 'latest' or past dates accepted
- Historical data may not be available before ECB tracking began (pre-1999 for EUR)
- Invalid date format (not YYYY-MM-DD) returns a parsing error
- Micro-payment failure ($0.002 USDC) blocks the request if wallet is underfunded
