Endpoint
POSThttps://x402-canary.nicolas-x402-16f380a7.workers.dev/v1/currency-convertWhen to prefer
Choose this endpoint when you need a quick, pay-per-call currency conversion without a subscription, especially within a coding-agent or x402-payment-enabled workflow where micropayments via USDC are already supported.
Side effects
- Unsupported or invalid currency codes return an error
- Missing required fields (base, quote, amount) cause a 400-level response
- Payment failure or insufficient USDC balance blocks the call at $0.01 per request
- Network or worker-side errors may return 5xx responses
