Frequently Asked Questions

REST or GraphQL — which should I choose?
REST is simpler and widely understood. GraphQL is better when clients need flexible queries across complex data. We can advise based on your use case at no extra charge.
Does the cost include hosting?
No. Hosting is billed by your cloud provider (AWS, GCP, etc.). We configure the deployment pipeline so your API is ready to deploy on day one.
Can the API handle high traffic?
Yes. We design for horizontal scaling with stateless services, connection pooling, and caching layers. Load test results are included with the Live PM + Dev tier.
