How does financial API current limiting protection prevent API abuse?

Financial API rate limiting protection prevents API abuse by controlling the number of requests a user or application can make within a specific time frame. This ensures fair usage, maintains system stability, and protects against malicious activities like DDoS attacks or data scraping.

How it works:

1. Request Quotas: Sets a maximum number of allowed requests per user, IP, or application over a defined period (e.g., 1000 requests per hour).
2. Throttling: Slows down or delays excessive requests once the limit is reached, instead of outright blocking.
3. Blocking: Temporarily or permanently denies access to users exceeding the limit.

Example:
A banking API might allow 500 transactions per minute per client. If a malicious actor tries to send 1000 requests in a minute, the rate limiter will either throttle the excess requests or block the client temporarily.

Tencent Cloud Solution:
Tencent Cloud API Gateway provides built-in rate limiting features, allowing developers to set custom quotas and throttling rules. It also integrates with Tencent Cloud's monitoring tools to detect and respond to abnormal traffic patterns in real time.
