API Base URL

The KiosAPI base URL and how to configure it correctly with your API key.

API Base URL

The KiosAPI base URL is:

https://kiosapi.com/v1/

All API requests should be sent to this address (or the appropriate sub-path for your chosen endpoint format). For example:

Endpoint	Full URL
OpenAI chat completions	https://kiosapi.com/v1/chat/completions
OpenAI responses	https://kiosapi.com/v1/responses
Claude native	https://kiosapi.com/v1/messages
Gemini native	https://kiosapi.com/v1beta/models/{model}:generateContent

Finding Your Current API Address

While the default base URL is https://kiosapi.com/v1/, you should always verify the current API address from your dashboard:

1. Log in to kiosapi.com.
2. Navigate to Dashboard > Console.
3. Check the displayed API base URL.

The API address shown in Dashboard > Console is the authoritative source. If the address ever changes, the dashboard will reflect the update first.

Configuring Your SDK

OpenAI SDK (Python)

from openai import OpenAI

client = OpenAI(
    base_url="https://kiosapi.com/v1/",
    api_key="sk-kioo-xxxxxxxxxxxx"
)

response = client.chat.completions.create(
    model="gpt-5.5",
    messages=[{"role": "user", "content": "Hello!"}]
)

OpenAI SDK (Node.js)

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://kiosapi.com/v1/",
  apiKey: "sk-kioo-xxxxxxxxxxxx",
});

const response = await client.chat.completions.create({
  model: "gpt-5.5",
  messages: [{ role: "user", content: "Hello!" }],
});

Anthropic SDK (Python)

import anthropic

client = anthropic.Anthropic(
    base_url="https://kiosapi.com/v1/",
    api_key="sk-kioo-xxxxxxxxxxxx"
)

message = client.messages.create(
    model="claude-sonnet-5",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Hello!"}]
)

A very common mistake is mixing up the base URL and API key. Here’s the rule:

• ✅ KiosAPI key → https://kiosapi.com/v1/
• ❌ KiosAPI key → https://api.openai.com/v1/ (will fail)
• ❌ OpenAI key → https://kiosapi.com/v1/ (will fail)

Your KiosAPI key only works with the KiosAPI base URL. Double-check both values in your dashboard before debugging authentication errors.

Environment Variable

You can also set the base URL via an environment variable to avoid hardcoding it:

# .env
KIOSAPI_BASE_URL=https://kiosapi.com/v1/
KIOSAPI_API_KEY=sk-kioo-xxxxxxxxxxxx

KiosAPI is designed as a drop-in replacement for OpenAI, Claude, and Gemini APIs. By setting the base URL to kiosapi.com, you can use any existing OpenAI-compatible SDK without changing your application logic — just swap the URL and key.
