CAMARA Network APIs
Interfaces to operator systems that power CAMARA / Aduna APIs — Deutsche Telekom subsidiaries in Slovakia and Czech Republic
instarea builds the interfaces to a mobile operator's internal systems that feed CAMARA Network APIs with live answers from the operator's own network and subscriber data. The CAMARA APIs themselves are exposed by the Deutsche Telekom group platform and offered worldwide through the Aduna global network-API aggregator. Interfaces built: Number Verification, SIM Swap and KYC lookup — the KYC lookup interface covers both CAMARA KYC Match and KYC Fill-in use cases. Built for two Deutsche Telekom subsidiaries: Slovak Telekom (Slovakia) and T-Mobile Czech Republic. Technically operational in Slovakia and the Czech Republic in 2026/2027; the commercial launch and its announcement are subject to the decision of each of the two operators (Slovak Telekom, T-Mobile Czech Republic). Delivered locally for the Slovak and Czech operator teams and legal entities as part of a Deutsche Telekom group programme that DT coordinates and actively participates in. Built as an extension of the instarea ServiceHub (Technical Service Hub) platform and ready to roll out to further operators and countries.
