All Adaline API requests and SDK calls require authentication via a Bearer token (API key).

​
Getting Your API Key

  1. Log in to the Adaline Dashboard
  2. Follow the steps to Create API Keys.

​
Using Your API Key

​
REST API

Include your API key in the Authorization header as a Bearer token: 
curl -X GET "https://api.adaline.ai/v2/some-endpoint" \
  -H "Authorization: Bearer YOUR_API_KEY"

​
TypeScript SDK

The SDK reads from the ADALINE_API_KEY environment variable by default: 
export ADALINE_API_KEY=your-api-key

import { Adaline } from "@adaline/client";

// Reads ADALINE_API_KEY automatically
const adaline = new Adaline();

// Or pass it explicitly
const adaline = new Adaline({ apiKey: "your-api-key" });

​
Python SDK

export ADALINE_API_KEY=your-api-key

from adaline import Adaline

# Reads ADALINE_API_KEY automatically
adaline = Adaline()

# Or pass it explicitly
adaline = Adaline(api_key="your-api-key")

​
Error Responses

If authentication fails, the API returns a 401 Unauthorized response: 
{
  "error": {
    "code": "UNAUTHORIZED",
    "message": "Invalid or missing API key."
  }
}
Common causes:
  • Missing Authorization header
  • Malformed token (missing Bearer prefix)
  • Expired or revoked API key
  • Key does not have permission for the requested resource
