# Swisscom **Canonical:** https://apis.io/providers/swisscom/ **Website:** https://www.swisscom.ch/ **APIs profiled:** 13 Swisscom is Switzerland's largest telecommunications provider and the incumbent mobile network operator, fixed-line carrier and IT services company for the Swiss market, majority-owned by the Swiss Confederation and also operating Fastweb in Italy. In the telecom value chain it is a facilities-based MNO that owns the radio access and core network, sells mobile, broadband, TV and enterprise IT, and monetises network-derived data. Its API posture is unusual for a European incumbent: alongside the expected partner-gated enterprise surface it runs a genuine first-party API marketplace at digital.swisscom.com listing ten productive API products (SMS, SMS token 2FA, inbound SMS, mobility heatmaps, dwell times, origin-destination, NATEL go smart catalogs, AI inference endpoints and a business identity validator) served from a live api.swisscom.com gateway, plus a separately maintained, actively released Swisscom Sign Integration API with a downloadable OpenAPI 3.1 document. The catch is that every API reference, key and spec beyond Swisscom Sign sits behind a Swisscom login and, for several products, a signed service contract — the marketplace is a storefront, not open documentation. On network APIs Swisscom was one of the 21 founding signatories of the GSMA Open Gateway Memorandum of Understanding in February 2023, but it publishes no CAMARA API, no Open Gateway developer portal and no callable network-API endpoint; developers who want SIM-swap or phone-verification signals from the Swisscom network have historically reached them through third-party channels such as IPification rather than from Swisscom directly. Its legacy developer programme (developer.swisscom.com, the Cloud Foundry Application Cloud, the swisscom-developer GitHub SDKs) is dead or redirected, and the older Messaging and Voice APIs are still documented only as RAML-rendered HTML in a GitHub wiki. ## Kin Score — 62.5 / 100 (strong) Scored 2026-08-17 under rubric 0.11.0.
