API JWT Authenticator Skill

When to Use This Skill

Use this conceptual skill when you need to implement secure JWT-based authentication for FastAPI REST APIs. This skill is appropriate for:

• Protecting API endpoints that require user authentication
• Enforcing user-specific access control (ensuring users can only access their own resources)
• Implementing stateless authentication in microservices
• Securing REST APIs with standard JWT token validation
• Adding role-based access control (RBAC) to API endpoints

This skill should NOT be used for:

• Public APIs that don't require authentication
• APIs that use alternative authentication methods (OAuth, API keys, etc.)
• Simple applications where basic auth is sufficient
