API Development

Robust APIs that connect your systems and scale with your business

We develop well-designed, documented and secure REST and GraphQL APIs. To integrate internal systems, expose data to partners, or power your mobile and web applications.

Why choose Deepyze?

We work with industry best practices to guarantee real results.

REST and GraphQL APIs

We design the right architecture for each case: REST for standard integrations and CRUD operations, GraphQL when clients need flexible and efficient queries.

Auto-generated docs (Swagger/OpenAPI)

The API ships with auto-generated interactive documentation. Any developer can explore endpoints, view parameters and test requests in real time.

Authentication and security (JWT/OAuth)

We implement JWT, OAuth 2.0 and API Key authentication. Role-based access control, HTTPS, input sanitization and protection against injection and common attacks.

Rate limiting and error handling

Abuse protection with configurable rate limiting. Consistent and descriptive error responses that simplify integration and debugging for consuming teams.

API versioning

We implement versioning strategies from day one so you can evolve the API without breaking existing integrations. Clients migrate at their own pace.

Automated testing

A unit and integration test suite covering critical endpoints. Tests run in CI/CD to guarantee every change doesn't break the API contract.

Our work process

A clear and transparent method so you always know which stage your project is at.

1

Contract design and scoping

We define resources, endpoints, data models and authentication flows. We document the API contract before writing a single line of code.

2

Backend development

We build the API with best practices: layer separation, error handling, logging and maintainable structure. We choose the tech stack based on context and requirements.

3

Security, testing and documentation

We implement authentication, rate limiting and security protections. We generate Swagger documentation and write the automated test suite.

4

Deployment and integration support

We deploy to production and support the team consuming the API during integration. We answer questions and adjust contracts if new requirements emerge.
