[Objective] This paper aims to find out the differences between the interface services of governmental open data platform in China and developing trends around the world. [Context] During the 13th Five-Year Plan period, China will build a national open data platform to promote the sharing and in-depth utilization of data at all levels, which demands huge amount of interface services. [Methods] We analyzed the major issues facing the open data platform interface services in China, based on the popular international open data platforms and the W3C API best practices. We also introduced the open data protocol OData to discuss key steps for launching standardized API services. [Results] Building OData services, issuing documentation and machine-readable metadata could help our API services follow best practices. [Conclusions] Adopting internationally accepted standards could improve user experience of interface services in China.
