GSMA Open Gateway
GSMA Open Gateway is the mobile industry's operator-commitment and certification layer for network APIs, run by the GSM Association from its London headquarters in the United Kingdom. Launched at MWC Barcelona on 27 February 2023 with 21 operator groups and eight universal network APIs, it is the go-to-market wrapper around CAMARA, the Linux Foundation-hosted Telco Global API Alliance that actually authors the OpenAPI definitions. GSMA sits above the value chain rather than in it: it signs operators and channel partners to a memorandum of understanding, certifies implementations against CAMARA service APIs and TM Forum Operate APIs, and publishes which certified APIs are live in which markets. Its API posture is honestly non-existent as a first-party surface. GSMA operates no callable API, publishes no OpenAPI under its own name, and runs no self-serve developer portal with keys or a sandbox. open-gateway.gsma.com is a filterable directory of certified deployments, and every automated probe of it and of gsma.com returned an HTTP 403 Cloudflare bot challenge. The specifications are open on GitHub under camaraproject and tmforum-apis; the endpoints belong to operators; and developers reach them through aggregators and channel partners such as Aduna, Vonage, Infobip, Sinch, Twilio, Nokia, AWS and Bridge Alliance rather than through the GSMA. Per the GSMA's own Q1 2026 Open Gateway update, 81 operator groups and 61 channel partners covering 292 networks and about 80 percent of global mobile connections have signed, with 237 certified API assets drawn from 33 CAMARA tagged released APIs and 280 API instances commercially launched across 85 networks in 50 markets.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles GSMA Open Gateway the way a machine reads it — 29 machine-readable artifacts across 22 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 — GSMA Open Gateway scores 50.3/100 (developing), with a separate agent-readiness read of 78/100 (agent native). 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.
How we profile GSMA Open Gateway
Each block below is one kind of artifact we hold for GSMA Open Gateway. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 22
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVEREvent Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

ASYNCAPISecurity Posture 3
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.
OAuth scopes governing access to this provider's APIs.
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.
