# API Inventory Scanner Skill

Discovers and documents existing API endpoints through code analysis, log inspection, and traffic analysis.

## Purpose

Enable API discovery for:
- Endpoint discovery
- Request/response format extraction
- Authentication method detection
- Rate limit identification
- Consumer mapping

## Capabilities

### 1. Endpoint Discovery
- Parse route definitions
- Analyze controller code
- Inspect API frameworks
- Find undocumented endpoints

### 2. Request/Response Format Extraction
- Extract request schemas
- Document response formats
- Identify query parameters
- Map headers and cookies

### 3. Authentication Method Detection
- Identify auth mechanisms
- Document token formats
- Map permission requirements
- Catalog security schemes

### 4. Rate Limit Identification
- Find rate limit configurations
- Document throttling rules
- Identify quotas
- Map limit tiers

### 5. Consumer Mapping
- Identify API consumers
- Track usage patterns
- Map client dependencies
- Document integrations

### 6. Usage Pattern Analysis
- Analyze access logs
- Identify hot endpoints
- Track response times
- Map error rates
