KiosAPI Introduction

KiosAPI is a unified AI API gateway for developers and teams. Use one account and API key to connect applications to supported models through OpenAI-compatible, Anthropic-compatible, and Gemini-compatible interfaces.
New to KiosAPI? Complete Account, Balance, and API Key, then follow the Quickstart.

​
One gateway, multiple API formats

Choose the protocol your existing SDK already expects. You do not need to rewrite an OpenAI integration just to use another supported model family.

​
Addresses to remember

A client may append /v1 automatically. If your request path becomes /v1/v1/..., configure the host as https://kiosapi.com instead. See Configuration Principles.

​
Start in three steps

1. Create an account

Register, review live pricing, and prepare a small test balance.

2. Create an API key

Generate a scoped token in the KiosAPI dashboard and keep it secret.

3. Make a test request

Choose a model and send a short request before configuring a full client.

​
Authentication overview

The key is the same, but the header depends on the protocol. Read Authentication before integrating a native Anthropic or Gemini client.
