We've just released sttp-ai 0.4.0 (formerly sttp-openai): you can now find clients for both OpenAI and Claude APIs. Same as sttp-client, the library works with any #Scala ecosystem: direct-style (synchronous), Future, cats-effect & ZIO. Enjoy!

Ox feature tour, day 19: because it's direct style, integration with OpenTelemetry (metrics+logging+tracing) "just works"! To propagate tracing context inside concurrency scopes, you only need a single switch at your top-level `OxApp`!

Ox feature tour, day 18: `.pipe` and `.tap`, even extremely simple, are suprisingly useful! And there's no overhead: these are inline methods, hence a "zero-cost abstraction". Bonus: discover the `debug`, `.discar` and `.tapException` methods!

Ox feature tour, day 17: converting exceptions to `Either`s, and vice versa is trivial thanks to the inline `.catching[]` and `.orThrow` methods. A panic at one level, might become an expected error at another!

Ox feature tour, day 16: we propose error handling based on "panics" (exceptions) and "expected" errors, represented as Eithers. Working with the lattter is ergonomic thanks to Scala's boundary/break, and its Ox-provided specialization to Eithers using `either: and `.ok()`
