API Key Authentication

Adaptive uses API key authentication with Bearer tokens. You’ll need to include your API key in the Authorization header for all requests.

​
Getting Your API Key

  1. Sign up at llmadaptive.uk
  2. Create a new project in your dashboard
  3. Navigate to API Keys section
  4. Generate a new API key
Keep your API key secure and never expose it in client-side code or public repositories.

​
Using Your API Key

​
In Headers

Include your API key in the X-Stainless-API-Key header: 
curl https://llmadaptive.uk/api/v1/chat/completions \
  -H "X-Stainless-API-Key: your-adaptive-api-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

​
With OpenAI SDK

import OpenAI from "openai";

const openai = new OpenAI({
  apiKey: "your-adaptive-api-key",
  baseURL: "https://llmadaptive.uk/api/v1",
});

​
Environment Variables

Store your API key in environment variables: 
# .env
ADAPTIVE_API_KEY=your-adaptive-api-key

const openai = new OpenAI({
  apiKey: process.env.ADAPTIVE_API_KEY,
  baseURL: "https://llmadaptive.uk/api/v1",
});

​
API Key Permissions

API keys provide access to:
  • Chat completions endpoint
  • Model listing endpoint
  • Usage analytics (for your account)

​
Rate Limits

Rate limits are applied per API key:
  • Free Tier: 100 requests per minute
  • Pro Tier: 1,000 requests per minute
  • Enterprise: Custom limits

​
Error Responses

​
Invalid API Key

{
  "error": {
    "message": "Invalid API key",
    "type": "invalid_request_error",
    "code": "invalid_api_key"
  }
}

​
