Authentication - TradingNews

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

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

Key Format

TradingNews API keys use a prefix format for easy identification:

Prefix	Environment
`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
