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
