Rate Limits

Each API key has a per-minute request limit based on your plan tier. Limits are enforced via a sliding window.

Rate Limit Headers

When you’re rate limited, the API returns 429 Too Many Requests: 
{ "detail": "Rate limit exceeded. Try again shortly." }

​
Best Practices

  • Cache responses — if you’re polling /v1/news frequently, cache results for a few seconds
  • Use WebSocket for real-time data instead of polling the REST API (Pro plan)
  • Spread requests — avoid bursting all requests in the first second of each minute

​
IP-Based Protection

TradingNews also monitors for abuse patterns. If a single IP address uses 3 or more different API keys within 1 minute, that IP is temporarily blocked for 10 minutes. This prevents credential stuffing attacks.
