Authentication

All API requests require authentication using a Bearer token. Your API key identifies your account and determines your rate limits and permissions.

Getting Your API Key

1. Sign up for a Speechgen account
2. Navigate to your Dashboard
3. Click on "API Keys" in the sidebar
4. Click "Generate New Key"
5. Copy and securely store your API key

Using Your API Key

Include your API key in the Authorization header of every request:

Authorization: Bearer YOUR_API_KEY

Example Request

curl -X GET https://api.speechgen.com/v1/voices \
  -H "Authorization: Bearer sk_live_abc123xyz..."

3. Monitor usage: Check your dashboard for unusual activity
4. Set up alerts: Configure notifications for rate limit warnings

# Store in environment variable
export SPEECHGEN_API_KEY="sk_live_your_key_here"

// Access in Node.js
const apiKey = process.env.SPEECHGEN_API_KEY;
