About This Service
A well-designed API is the backbone of any modern web or mobile application. At WebCraftera LLP, we build REST and GraphQL APIs that are reliable, secure, and easy for frontend teams to consume. Every API we deliver includes OpenAPI (Swagger) documentation, JWT authentication, rate limiting, input validation with Zod or Joi, and comprehensive error handling with meaningful status codes.
We version APIs from the start, ensuring backward compatibility as your platform evolves. Our APIs are containerised with Docker, deployed behind Nginx or AWS API Gateway, and monitored with uptime alerts and response time tracking. Whether you need a microservices backend or a single monolithic API, we build for correctness, performance, and maintainability.
