Nfon
NFON AG is a European provider of cloud telephony and unified communications (UCaaS/CPaaS), headquartered in Munich and serving businesses across 15+ European countries. Its Cloudya cloud phone system and related products deliver business voice, video, contact centre and AI-assisted communication. For developers and integration partners, NFON publishes a set of RESTful JSON APIs hosted from the NFON-AG GitHub organisation: the flagship PBX Configuration API (OAuth 2.0, ~480 operations for provisioning tenants, extensions, devices, queues, groups, IVRs, phone books, licences and more — the successor to the legacy Service Portal API), the CTI API (server-to-server call control and Server-Sent-Event call/state streaming), and the Call History API offered under "Login with NFON" (OAuth 2.0 Authorization Code + PKCE) for retrieving, streaming and deleting call records with transcriptions and summaries. Use of the APIs is free of charge; access is provisioned by contacting [email protected].
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 Nfon the way a machine reads it — 57 machine-readable artifacts across 52 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 — Nfon scores 48.9/100 (developing), with a separate agent-readiness read of 69/100 (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 Nfon
Each block below is one kind of artifact we hold for Nfon. 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 52
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.

Postman Collections 1
A runnable collection turns the contract into something a developer can execute in seconds. We profile them because the fastest way to trust an API is to make a real call against it.
Ready-to-run Postman collections for exercising this provider's APIs.
MCP Servers 1
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 SERVERSecurity Posture 2
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.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
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.
Recommended x-agentic-access execution contracts for AI agents.
