APIs Simulators
API security depends on strong authentication, object-level authorization, rate controls, data minimization and safe key handling. A secure API validates both who is calling and what that caller is allowed to access.

What to watch for
- Requests accessing objects outside the expected user scope
- Sudden spikes from one identity or token
- Unexpectedly large API responses
- Keys appearing in browser code, logs or public repositories
- Authorization decisions made only in the client
Defensive priorities
- Authenticate every sensitive request
- Enforce object- and role-level authorization server side
- Apply rate limits and abuse detection
- Return only the data a caller needs
- Rotate and scope API keys; never expose privileged keys in client code
