8x8
8x8, Inc. is a San Jose, California headquartered cloud communications provider that sells an integrated UCaaS, CCaaS and CPaaS platform (marketed as XCaaS) to business buyers in its home market of the United States and internationally. In the telecom value chain 8x8 sits in the aggregator half of the market, not the mobile network operator half: it does not own radio spectrum, and it resells carrier voice and messaging connectivity while adding contact center, unified communications, video (it owns and operates Jitsi as a Service) and analytics on top. Its API posture is genuinely developer-first for a company of its size — developer.8x8.com is a real self-serve portal, sign-up runs through the 8x8 Connect console, and the entire documentation site including 34 OpenAPI 3.x definitions is published openly on GitHub at 8x8Cloud/public-developer-docs. What 8x8 does not do is the network-API layer: there is no CAMARA reference, no GSMA Open Gateway participation, no Aduna channel, no TM Forum Open API conformance and no CIBA anywhere in its public developer corpus. 8x8 competes with Twilio, Vonage and Sinch on application-layer communications APIs, and buys the underlying network access rather than exposing it.
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles 8x8 the way a machine reads it — 45 machine-readable artifacts across 36 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 — 8x8 scores 67.0/100 (strong), with a separate agent-readiness read of 90/100 (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 8x8
Each block below is one kind of artifact we hold for 8x8. 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 36
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.

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.

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

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.

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.

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.

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.
