Technical details
Endpoint
POSThttps://x402-hub.vercel.app/api/crypto-exchangeWhen to prefer
Choose this endpoint when you need real-time or near-real-time cryptocurrency exchange rate data and are operating in an x402 micropayment-enabled environment on Base. It is well-suited for agents that need to fetch spot prices or conversion rates for crypto assets without managing a full exchange API integration. At ~$0.13 per call, it is appropriate for occasional lookups rather than high-frequency trading data feeds.
Side effects
- Invalid or unrecognized cryptocurrency query string returns an error or empty data
- Upstream API unavailable results in failed response
- Payment not fulfilled via x402 protocol returns 402 Payment Required
- Malformed query parameter returns validation error
- Rate limits on upstream provider may cause intermittent failures
