Deutsche Telekom

Deutsche Telekom AG is Europe's largest telecommunications operator, headquartered in Bonn, Germany, serving more than 250 million mobile customers across 50+ countries. It is the parent company of T-Mobile US (NASDAQ TMUS) and the majority owner of T-Systems International, its enterprise IT and cloud arm. For developers, Deutsche Telekom operates a public developer portal at developer.telekom.com offering a MagentaBusiness CPaaS suite (SMS, RCS, Voice, Video, Conversational Connect, Reports, AI Studio) built in partnership with Vonage, plus a growing portfolio of GSMA Open Gateway / CAMARA-aligned Network APIs (Number Verification, Verify, 5G Slices) launched jointly with T-Mobile US. T-Systems operates Open Telekom Cloud, an OpenStack-based sovereign public cloud with full REST APIs across compute, storage, networking, container, database, AI, and API Gateway services. Deutsche Telekom is also a substantial open-source contributor — its github.com/telekom organization publishes 245+ repositories including the Open Telekom Integration Platform (O28M), the TARDIS control-plane suite (with OpenAPI 3 specs for Rover, Controlplane, Identity, Discovery, File Manager, Secret Manager, and Stargate), the Horizon pub/sub event-streaming ecosystem, the Scale design system, Wurzel RAG ETL framework, and Kubernetes-native networking and IPAM operators.

agent aware

Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.

Kin Score
travel_explore apis.io index code GitHub sourcepublic Website

API Evangelist profiles Deutsche Telekom the way a machine reads it — 115 machine-readable artifacts across 8 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Deutsche Telekom scores 28.6/100 (thin), with a separate agent-readiness read of 20/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Deutsche Telekom

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.

Where this information came from

This is an independent, third-party profile of Deutsche Telekom, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
