KDDI Corporation is a Japanese multinational telecommunications operator headquartered in Tokyo, providing mobile, fixed-line, broadband, and enterprise ICT services. KDDI markets its consumer mobile services under the au brand, alongside UQ mobile and povo, and serves enterprise customers globally through KDDI Global and KDDI America. The company operates the KDDI Open API for Developers portal exposing inquiry-gated product APIs including the au PAY Mini App platform, an XR/MEC low-latency application API, a PPM consent management API, and an au mobile Identification Support Service for KYC/identity verification. KDDI also runs the au OPEN DEVICE DEVELOPER SITE for cellular module device certification, and a KDDI Cloud Platform Service knowledge site with developer API references for cloud infrastructure. In 2025 KDDI became an equity partner in Aduna, the GSMA/Ericsson-backed network API venture aggregating CAMARA-aligned carrier APIs (Number Verify, SIM Swap, Quality on Demand, Device Location) across global operators. Public OpenAPI specifications are not openly published; API access is provided through contact/inquiry workflows after partner onboarding.
