An interactive concept flow for designing apis around explicit semantics, from its assumptions through the main operation and boundary checks.
trace / request.md
readyAn API contract defines the meaning of operations, inputs, outputs, errors, and side effects. A good contract lets clients reason about retries and compatibility without depending on undocumented server behavior. HTTP methods communicate broad intent, while the application contract defines the resource-specific rules.
Use the stages in order to explain designing apis around explicit semantics. Each stage makes one assumption visible: what the operation promises, what representation it uses, how state changes, which boundary can invalidate a shortcut, and what evidence confirms the result.
For a worked explanation, continue to the topic article and execution trace.
