About OpenAPI

$16 per month

I believe the specification is the source of truth, which is why I maintain it separately from the code. The document is 1,400 lines, meticulously hand-crafted, with examples, descriptions, and a changelog.

Code generation is for people who do not trust themselves. I trust myself completely, which is why the implementation has 47 fields the spec has never heard of.
