  • oapi-codegen

    Generate Go client and server boilerplate from OpenAPI 3 specifications

    The service you're using has a swagger so you should try to create proper models in the first place. There are go code generators such as oapi-codegen. This style of programming is only good for throw-away code, python works well for that, if it's all you need, well, maybe stick to python in the first place. Yet even in python it's not considered production-ready good practice, proper code should use type-safe bindings such as with pydantic
