API Engine - Automated API documentation

API Engine logo

API documentation bears no value unless Sample Codes aids the developers.

API Engine, one of the digital services offered by Platform of Trust, aims to reduce developers' pain by taking away the manual effort of generating and updating API documentations. Additional advantages are Code samples, generated in parallel, to reduce time and resource allocations for manual development efforts.

Originally developed to maintain Platform of Trust APIs, API Engine takes machine-readable API specs in Open API Spec (OAS) - version 2 format as inputs and automatically generates human-friendly API documentation with enhanced readability. Developer eXperience is taken one step further by simultaneously producing ready-to-be-used code examples for all API endpoints and methods within the spec file.

2-click solution with generated code examples

API providers can simply focus on improving API functionalities and performance as generating documentations is now a simple 2-click action! Generated code examples reduce the effort to learn the know-hows of API usage, hence enabling third party developers to ensure great user experience on offered services

Features in a nutshell

  • Generate API documents from specs given as an URL or uploaded file
  • Produce sample codes in Java, Python, cURL, and Javascript for each API endpoint and method (more languages coming up soon!)
  • Validate and Execute generated code examples (optional, requires test API environment)
  • Store generated documentation and sample codes in your customized subdomain (with no worries about hosting)
  • See visualized progress for documentation and code example generation process
  • Take advantage of white-label branding (customized logo and CSS for look-&-feel) for creating a SaaS solution
  • With API Engine, we ensure 99% service level agreement (SLA) and added community support in Stack Overflow
