vscode-openapi VS swagger-editor

If you prefer working offline, there is a nice extension for VS Code to edit your API definition called OpenAPI (Swagger) Editor (https://github.com/42Crunch/vscode-openapi).

I did the same for the other API and adjusted the spec using the Swagger Editor. Specifically, I added detailed descriptions that should help the agent understand the API usages. The resulting OpenAPI YAML file is as follows:

It has an online editor. You can easily play around with it and generate easy-to-use documentation.

After running the collection, I can see the API spec that was created and the mock server endpoint to test it. Looking at the rendered version on Swagger's OAS editor we can see pretty clearly this is a complete API that gets us exactly what we need.

While there’s not an officially supported Java SDK for Marqeta, building a Java client is quite straightforward, as the Core API is documented in both Swagger v2.0 and OpenAPI v3.0. The OpenAPI documentation is in beta, but it is generated directly from the API source code. To get a Java client, all we need to do is drop the OpenAPI yaml file into editor.swagger.io, modify the servers section to use the https://sandbox-api.marqeta.com/v3 as the URL, and tell it to generate a Java client.

Check out https://editor.swagger.io/ as a start point. In theory you should be able to generate a client for any swagger complient api and plug in your own auth and custom logic.

I would suggest using the swagger editor: https://editor.swagger.io/

Paste your json into https://editor.swagger.io and it will ask you if you want to convert it to yaml

Sure. You can use the editor from here for instance to define your endpoints and the data received and returned. By looking at the preloaded example you can figure out most of what you need to know about openapi. But if you need more info, the official documentation is pretty good.

Optional: If you make any changes to the plugin instructions or metadata models, you can also copy the contents of main.py into the main main.py file. This will allow you to access the openapi.json at http://0.0.0.0:8000/sub/openapi.json when you run the app locally. You can convert from JSON to YAML format with Swagger Editor. Alternatively, you can replace the openapi.yaml file with an openapi.json file.
