API Development
Well-designed APIs other developers enjoy using.
Versioned, documented, well-behaved APIs that other teams enjoy integrating with.
Capabilities you get
Contract-first design
An OpenAPI specification agreed before build, so clients and server stay in step.
Security and rate limiting
OAuth, API keys, throttling and input validation applied consistently.
Developer documentation
Interactive reference, examples and a sandbox for integrators.
Fixed scope, fixed price
Well-defined work is quoted at a fixed price, and anything exploratory is time-boxed with a clear checkpoint.
You own everything
Code, designs, documentation and data belong to you from the day they are created.
Named senior engineer
One accountable person who knows your system, rather than a rotating cast.
Overview
Versioned, documented, well-behaved APIs that other teams enjoy integrating with.
We design and build REST and GraphQL APIs with versioning, authentication, rate limiting, observability and complete developer documentation.
How we approach api development
We build in thin vertical slices that reach a real environment early, so you review working software every week instead of status reports. The architecture is documented as we go, the test suite grows with the code, and the delivery pipeline exists from the first sprint — which is what makes the later weeks calm rather than frantic.
What success looks like
Stable, documented, secure interfaces that let your systems and partners integrate with confidence. We agree the measures that define success with you in the first week, report against them throughout, and review them together after launch.
How the engagement runs
- Discovery — a short, paid phase that ends with a scope, an architecture and a fixed estimate you own whether or not you continue with us.
- Build — weekly working releases, a shared backlog and a named lead engineer you can reach directly.
- Launch and support — staged rollout, handover training and a defined support period afterwards.
What you walk away with
- A working api development solution in production
- Source code in your repository from day one, with full commit history
- Automated test suite and continuous-integration pipeline
- Architecture decision records and developer onboarding guide
- Production and staging environments with infrastructure as code
- Performance and security baseline report
- Handover session and 30 days of post-launch support
Common questions
- How long does api development usually take?
- Typically 4–8 weeks, depending on scope and how many systems are involved. Discovery produces a firm timeline before you commit to the build.
- What does api development cost?
- Engagements typically start from $6,000. We quote fixed prices for well-defined scope and give you a written estimate at the end of discovery, with every assumption listed.
- Who owns the code?
- You do. On payment the intellectual property transfers to you, and the code lives in your repository throughout the engagement. We retain only our general know-how and pre-existing tooling, which we license to you for use within the delivered work.
- Can you work alongside our existing developers?
- Yes, and it is a common arrangement. We work inside your source control, issue tracker and review process, and we pair with your engineers so the knowledge stays with your team.
