Exchange Rate & Currency Conversion API Overview

The Exchange Rate & Currency Conversion API helps developers quickly integrate currency lookups and conversion processing into their systems. It returns structured data, making it ideal for financial business integration, account reconciliation, and automated system integration.

Use Cases

Integrate exchange rate and currency conversion capabilities into internal systems, SaaS platforms, automated workflows, or admin dashboards.
Suitable for business scenarios requiring stable API calls, standardized responses, and orchestratable interfaces.
We recommend implementing rate limiting, retry mechanisms, and result caching strategies to improve overall integration stability.

Integration Guidelines

Verify request parameter formats, authentication methods, and error code handling logic before integration.
For high-frequency query scenarios, ensure proper log tracking, timeout controls, and idempotency handling.
If the results are used for risk control or automated decision-making, we recommend applying secondary validation based on your business rules rather than relying solely on the API response.

Integration Examples

Includes ready-to-use Shell, Python, Go, Java, and PHP examples for direct integration.
