Rate Limits - TradingNews

Rate Limits

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

Plan	Requests per Minute
Starter	1
Pro	30
Max	60
Expired (7-day grace)	1

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 and Max plans)
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.
