Professional REST API development. We build RESTful APIs with proper resource design, authentication, pagination, versioning, and comprehensive documentation.
Get Started
REST remains the standard for web APIs β but many REST APIs are poorly designed, inconsistent, and hard to use. We build REST APIs that follow best practices: predictable URL structures, proper HTTP methods, consistent error responses, efficient pagination, and documentation that developers actually want to read.
We build REST APIs with Express, Fastify, or NestJS on Node.js, FastAPI on Python, or Chi/Gin on Go. OpenAPI specification drives documentation, code generation, and testing. APIs deploy on Vercel, AWS, or Kubernetes with proper API gateway configuration.
Teams building public-facing APIs for partners and developers, internal APIs connecting microservices, or B2B APIs for product integrations. We deliver REST APIs that follow standards, perform well, and provide excellent developer experience.
Model resources, define endpoints, authentication model, pagination strategy, and error conventions.
Write OpenAPI spec, define schemas, set up mock server, and validate design with consumers.
Implement endpoints, authentication, validation, rate limiting, and business logic.
Write integration tests, generate interactive docs, and create getting-started guides.
Deploy, set up monitoring and analytics, publish docs, and onboard first API consumers.
Let's build a REST API that developers love β well-designed, well-documented, and reliable.
We build REST APIs using Node.js with Express or Fastify, Python with FastAPI or Django REST Framework, Go with Gin, and .NET Web API. We choose the stack based on your performance requirements, team expertise, and ecosystem needs.
MicrocosmWorks offers REST API development at $15-$45/hour. Costs depend on the number of endpoints, authentication complexity, rate limiting requirements, and integration with external services.
Yes, we implement API versioning via URL path or headers, auto-generate OpenAPI/Swagger documentation, use consistent error response formats, and follow HATEOAS principles where appropriate for discoverability.
Absolutely. We implement OAuth2 with JWT tokens, role-based and attribute-based access control, API key management, rate limiting per client, and scope-based permissions to secure your REST API endpoints.
We implement cursor-based pagination for consistent results, flexible filtering with query parameters, sparse fieldsets to reduce payload size, and ETag-based caching to minimize bandwidth usage on frequently accessed endpoints.
