API Gateway Architect & Troubleshooting Advisor
Architect & troubleshoot API gateways with AI-guided decisions
What You Can Do
You can design production-ready API gateway architectures tailored to your scale, troubleshoot routing and performance issues with step-by-step diagnostics, and implement rate limiting and security policies from scratch. Claude guides you through technology choices (Kong, AWS API Gateway, Nginx, Envoy), architectural trade-offs, and configuration decisions. Get instant analysis of existing setups and recommendations to eliminate latency, reduce errors, and secure your services.
Features
Evaluate Kong, AWS API Gateway, Nginx, Envoy, Traefik with cost, performance, and operational complexity analysis
Build intelligent request routing, canary deployments, A/B testing, and geolocation-based service routing
Implement token bucket, sliding window, and adaptive algorithms tailored to your traffic patterns
Set up OAuth2, JWT validation, CORS policies, request/response transformation, and API authentication
Diagnose latency, timeouts, error spikes, and throughput issues with root cause analysis and fix prioritization
Evaluate current gateway designs for scalability, security, cost efficiency, and operational burden
Plan logging, distributed tracing, metrics, and alerting strategies for gateway health and performance
Example Output
Design Example: You ask: "I need to choose between AWS API Gateway and Kong for 10M requests/day across 50+ microservices."
Claude returns:
- ✅ Detailed comparison table (latency, scaling, cost, operational overhead)
- ✅ Recommendation with reasoning
- ✅ Architecture diagram with deployment topology
- ✅ Cost projection for 12 months
- ✅ Migration path if you switch later
Troubleshooting Example: You ask: "API Gateway adds 200ms latency. Config: [pasted]. Where do I start?"
Claude returns:
- 🔍 Diagnostic checklist with expected outputs
- 📊 Root cause ranking (backend latency 40% → routing inefficiency 30% → TLS overhead 20%)
- ⚙️ Configuration changes to test
- 📉 Expected latency reduction per fix
Security Example: You ask: "Implement rate limiting (100 req/min per user) and OAuth2 token validation."
Claude returns:
- 🔐 Token bucket algorithm with TTL/caching strategy
- 💻 Code samples for Kong/AWS/Nginx
- ✓ Security checklist (replay attacks, token expiry handling)
- 🧪 Testing strategy for rate limits and auth failures
