Contracts before clients.
Public behavior belongs in a precise contract before it becomes a convenience in an SDK.
Inttegro / Engineering
The great dares
behind those who
dare greatly.
“The credit belongs to the man who is actually in the arena … who at the worst, if he fails, at least fails while daring greatly.”
— Theodore Roosevelt, Citizenship in a Republic, 1910

Featured work
A shared language for typed HTTP services.
HTTPAPI separates a service contract from any one language or description format. Its specification makes the runtime, validation, projection and error semantics implementable anywhere.

Open source
We publish the seams.
Contracts, SDKs, tools and examples are easier to trust when their design and implementation can be inspected.
Protocol
HTTPAPI
A typed HTTP contract and execution model, with a language-neutral specification and a Go reference implementation.
SDK
Inttegro JS
The browser runtime and framework adapters behind Inttegro Checkout on the web.
Tooling
Inttegro AI
Open-source skills, plugins, protocol integrations and diagnostics for agent-built Inttegro applications.

Writing
Notes from the work.
Specifications and field guides written while designing, operating and extending Inttegro.
Specification
HTTPAPI Specification 0.2
The language-independent contract for interoperable typed HTTP services, response projections and structured errors.
Field guide
Checkout lifecycle and reconciliation
How hosts should interpret checkout events, reconcile terminal outcomes and recover from interrupted browser sessions.
Field guide
Security, CSP and accessibility
The browser boundary for hosted Checkout, including content security policy, focus management and accessible fallbacks.

How we build
State tells the truth.
Commerce systems should model real lifecycle outcomes, not hide uncertainty behind a successful request.
Machines are readers.
Technical material should help both people and agents find the right answer without reconstructing our architecture.
Product documentation lives in Studio.
API reference, integration guides, SDK documentation, machine-readable pages and working demos have one dedicated home.
