What Is API Abuse? How Bots Exploit APIs
API abuse explained: how bots automate valid operations for fraud, scraping, account takeover, and cost exhaustion, and how application controls stop them.

Bot protection guides
Detection and application-layer defenses for automated abuse and malicious bots.
What these guides cover
Bot protection distinguishes approved automation from clients that use legitimate application features for fraud, scraping, spam, account takeover, inventory hoarding, or resource exhaustion. A bot is not defined only by its IP address or browser headers: sophisticated automation distributes activity across networks and accounts while preserving cookies and valid request schemas. Detection therefore correlates identity, network, device, behavioral, and business-outcome signals. Enforcement should protect the abused operation itself, use stable application identifiers where possible, and begin uncertain policies in dry-run mode so teams can measure legitimate-user impact before blocking traffic. Response design must account for attackers changing tactics after each enforcement step.
Risks
- Credential stuffing and account enumeration
- Scraping, fake accounts, spam, and promotion abuse
- Inventory hoarding, carding, and workflow fraud
- Distributed low-and-slow resource exhaustion
Control priorities
- Correlated identity, network, device, and behavior signals
- Operation-specific limits and workflow safeguards
- Bot classification without replacing authorization
- Dry-run tuning, false-positive review, and adaptation monitoring
Recommended reading order
Use the API abuse guide to classify the abused business operation, identify correlated signals, choose layered controls, and build an active-incident response. Follow its links to the API security and rate limiting guides for implementation detail.
