Technical details
Endpoint
GEThttps://206-81-14-131.sslip.io/svc/currency-rates/rate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, no-account, pay-per-call currency rate lookup using x402 micropayments on Base (USDC). Ideal for AI agents that need occasional rate checks without committing to a subscription or managing API keys. Best for simple base-to-target rate lookups rather than bulk historical data or deep forex analytics.
Side effects
- Unsupported currency code returns an error or empty result
- Network timeout if the upstream rate provider is slow
- Invalid currency symbol format causes a bad request error
- Rate data may be slightly delayed rather than real-time tick data
