API Key Authentication
All each::labs APIs use API key authentication via the X-API-Key header.
curl https://api.eachlabs.ai/v1/models \
-H "X-API-Key: YOUR_API_KEY"
Getting Your API Key
- Sign in to eachlabs.ai
- Navigate to Settings > API Keys
- Click Create API Key
- Copy and store your key securely
Your API key grants full access to your account. Never expose it in client-side code, public repositories, or logs.
Using the API Key
Include the X-API-Key header in every request:
curl https://api.eachlabs.ai/v1/models \
-H "X-API-Key: YOUR_API_KEY"
Authentication per Product
| Product | Header | Base URL |
|---|
| each::api | X-API-Key | https://api.eachlabs.ai |
| each::workflows | X-API-Key | https://workflows.eachlabs.run/api/v1 |
| each::sense | X-API-Key | https://eachsense-agent.core.eachlabs.run |
Some endpoints like GET /v1/models (listing models) do not require authentication. Check individual endpoint documentation for details.
Authentication Errors
If your API key is missing or invalid, you’ll receive a 401 response:
{
"error": "Invalid or missing API key"
}
Common Causes
| Issue | Solution |
|---|
| Missing header | Add X-API-Key: YOUR_KEY to your request headers |
| Invalid key | Verify the key in your dashboard |
| Expired key | Generate a new API key |
| Wrong product URL | Ensure you’re using the correct base URL for the product |
Security Best Practices
- Store API keys in environment variables, never in source code
- Use different keys for development and production
- Rotate keys periodically
- Revoke compromised keys immediately from your dashboard
