01 / Overview

What this service delivers

Partners integrate quickly when they are not forced to reverse-engineer your endpoints. We either design the API with you or formalise the one already running, bringing consistency to resource naming, predictable behaviour to paging and filtering, error responses that identify the offending field, and a versioning approach that allows the product to evolve. The specification is delivered in a machine-readable format together with a browsable console and a mock server generated from it. A contract this exact also gives AI coding assistants far less room to guess.

Who it suits, and what we need from you

Ideal for

  • Teams still tracking their API documentation in a spreadsheet

What we need from you

  • Access to the code, or an inventory of endpoints currently live
  • An engineer free for two design sessions
  • Any partner or contractual requirement the API has to meet

You share these through the technical brief in your dashboard after checkout.
