Apart from conducting regular vulnerability testing, we ensure API security by implementing industry-standard best practices. We also use encryption to protect data in transit and at rest, apply rate limiting to prevent abuse, comply with relevant security standards, and more.

We use Node.js with Express.js and NestJS, PHP with Laravel, and Go (Golang) with frameworks like Gin, Gorilla, Mux, and Net/HTTP for custom API development tailored to your needs.

To ensure scalability, we design APIs with modular, microservices-based architecture, enabling independent scaling of components. We use cloud-based infrastructure and load balancers to handle traffic spikes efficiently. To future-proof your API, we follow versioning best practices, utilize open standards like REST or GraphQL, and build with extensibility in mind.

We use best practices for data validation and verification to ensure data integrity and consistency, including schema enforcement and data type checks, business logic validation, versioning and tracking of data changes, error handling and logging, monitoring and alerting for continuous quality assurance, and more.

The cost of building a custom API can vary from $10,000 to $30,000 or more depending on several factors, including the specific needs and scope of the project.
