Bot Abuse in AI APIs: Why Your LLM Endpoint Is a Target

Unsecured LLM API endpoints are vulnerable to bot abuse techniques such as prompt farming, cost-inflation attacks, and data harvesting, which can cause significant financial and reputational damage. The root cause is the lack of proper security measures like rate limiting, anomaly detection, and authentication hardening. Implementing tools such as Flask-Limiter and robust access controls is essential to mitigate these threats.
