Problem¶

No visibility into API usage patterns. No per-user rate limiting or quotas.

Missing Features¶

1. Per-user API usage dashboard
2. Rate limiting by endpoint/user
3. Quota enforcement (e.g., 1000 requests/day)
4. Usage metrics (requests, bandwidth, compute time)

Implementation Plan¶

1. Create api_usage_logs table (timestamp, user_id, endpoint, response_time, status_code)
2. Add middleware to log all requests
3. Create GET /api/v1/usage/summary endpoint
4. Add X-RateLimit-* headers to responses
5. Configurable rate limits per endpoint

Rate Limit Configuration¶

Files to Create/Modify¶

• app/Http/Middleware/LogApiUsage.php
• app/Models/ApiUsageLog.php
• database/migrations/ (api_usage_logs)
• routes/api_v1.php (usage endpoints)
• config/api.php (rate limits)

Benefits¶

• Prevent abuse
• Track usage patterns
• Identify performance issues
• Enable tiered pricing
