Get API Metrics
Returns Prometheus-formatted metrics for all API endpoints. Tracks request counts, durations, sizes, errors, and active requests across normalized endpoint patterns. Metrics are exposed with appropriate labels for method, endpoint, and status.
Metrics exposed:
- sophra_api_requests_total: Counter of total API requests by method, endpoint, and status
- sophra_api_request_duration_seconds: Histogram of request durations by method and endpoint
- sophra_api_response_size_bytes: Histogram of response sizes by method and endpoint
- sophra_api_errors_total: Counter of API errors by method, endpoint, and error type
- sophra_api_active_requests: Gauge of currently active requests by method
