# Other languages

Python, Ruby, PHP, Go, Java and C# have packages of their own. Everything else generates from the spec.

## Generate one from OpenAPI (not built yet)

Python, Ruby, PHP, Go, Java and C# have official packages, listed below. Other languages arrive in the order people ask for them. Until then the OpenAPI document generates a usable client in most of them, and because the request schemas are derived from the same zod that validates them, it cannot describe a field the server would reject.

**generate.sh**

```
curl -s https://api.nextmail.sh/openapi.json -o openapi.json
openapi-generator generate -i openapi.json -g rust -o ./client
```
