Hello all,

apologies for a potentially stupid question: would it make sense to generate Json schema from tapir Schema? So far we are using [GitHub - andyglow/scala-jsonschema: Scala JSON Schema](https://github.com/andyglow/scala-jsonschema), but this is yet another derivation path to handle.

Yes, you can use OpenAPI 3.1 (which isn’t yet supported by swagger, hence it’s not the default), where the schemas are a superset of json schemas as far as I remember. Take a look at [GitHub - softwaremill/sttp-apispec: OpenAPI, AsyncAPI and JSON Schema Scala models.](https://github.com/softwaremill/sttp-apispec), it would be good to know what’s missing (either in code or documentation) to address these use-cases.

Thank you for pointing into this direction! I stumbled uopn `sttp.tapir.docs.apispec.schema.Schemas` but could not find a way to instantiate it, other than to copycat the code from `sttp.tapir.docs.openapi.EndpointToOpenAPIDocs`.

I believe we are missing an api which would allow to convert `sttp.tapir.Schema` into `sttp.apispec.Schema`. Currently, glue code components are package-private (like `sttp.tapir.docs.openapi.EndpointToOpenAPIDocs`).

Ah yes, you are right, that’s not exposed right now. But this can be changed of course 😉

Please create an issue 🙂 And/or a PR - this would probably go to the `apispec-docs` module

Out of curiosity, can you share what is your use-case?

Here is the ticket (no PR ☹ ) with some rationale: [Expose converters from tapir Schema to Json Schema (sttp.apispec.Schema) · Issue #2838 · softwaremill/tapir · GitHub](https://github.com/softwaremill/tapir/issues/2838)
