API Key Authentication

All API requests require an API key passed via the X-API-Key header. 
curl -H "X-API-Key: tn_live_your_key_here" \
  "https://api.tradingnews.press/v1/news"

​
Getting Your API Key

  1. Sign up at tradingnews.press
  2. Go to Dashboard > API Keys
  3. Click Create Key
  4. Copy the key immediately — it’s only shown once

​
Key Format

TradingNews API keys use a prefix format for easy identification:
PrefixEnvironment
tn_live_Production
tn_test_Sandbox (coming soon)

​
Security Best Practices

Never expose your API key in client-side code, public repositories, or browser JavaScript. Always call the TradingNews API from your backend server.
  • Store keys in environment variables, not in code
  • Use different keys for different applications
  • Revoke and rotate keys if you suspect exposure
  • Each key has independent rate limits and usage tracking
