A versioned API contract with OpenAPI docs, worked examples and a mock server your partners can build against today.
Overview
Partners integrate faster when they are not reverse-engineering your endpoints. We design or document your API properly: consistent resource naming, predictable pagination and filtering, error responses that name the field at fault, and versioning that lets you change things later without breaking anyone. The OpenAPI specification is published with a browsable console and a mock server, so an external developer can write and test their side before your implementation is even finished.
