instarea has built the operator-side interfaces that power CAMARA Network APIs for Slovak Telekom and T-Mobile Czech Republic — both Deutsche Telekom subsidiaries. The CAMARA APIs themselves are exposed by the Deutsche Telekom group platform and offered to developers and enterprises worldwide through Aduna. In both countries they are technically operational in 2026/2027; the commercial launch and its announcement are the decision of each of the two operators.
instarea built the piece every operator needs before a CAMARA API can go live in its country: the interfaces to the operator's own internal network and subscriber systems that feed the group's CAMARA exposure platform with live answers.
What is built: • Number Verification interface (Slovakia, Czech Republic) — network-based, OTP-less confirmation that a phone number belongs to the SIM in the device. • SIM Swap interface (Slovakia, Czech Republic) — tells a bank whether the SIM behind a number was recently changed, stopping account takeover. • KYC lookup interface (Slovakia) — one interface to verified subscriber data that covers two CAMARA use cases: KYC Match (match identity attributes without disclosing personal data) and KYC Fill-in (pre-fill onboarding forms with verified data, with the customer's consent).
What we delivered — end to end: 1. Project initiation with the Deutsche Telekom group programme team. 2. Analysis and detailed design aligned with the group CAMARA exposure architecture, including southbound API specifications. 3. Onboarding support to the group exposure platform — certificates, OAuth 2.0, endpoints. 4. Interfaces to operator systems (API resolvers) built as an extension of our ServiceHub platform. 5. Registration, CI/CD and rate limits on the group platform. 6. End-to-end, mTLS security and billing verification testing. 7. Pilot with the first service provider, performance baseline and go-live readiness — plus a dedicated, independent instance for T-Mobile CZ.
Why it matters: CAMARA and GSMA Open Gateway turn operator networks into standard APIs that banks, fintechs and e-commerce can use with one integration across many countries. Each operator, however, still has to connect its own internal systems — and that is where projects stall. The Czech rollout reused the Slovak foundation, which proves the approach is repeatable.
We are ready to deliver the same operator-side interfaces for other Deutsche Telekom subsidiaries and for any mobile operator joining Aduna or GSMA Open Gateway. Reach out at hello@instarea.com or visit instarea.com/products/camara-network-api.
