TypeSafeClient, ApiKey, TypeSafeException, the wire DTOs, and the JsonCodec/HttpTransport SPIs. Zero dependency on any particular JSON or HTTP library — plug in typesafe-java-jackson2/typesafe-java-jackson3 and typesafe-java-client-jdk (or your own implementations). The DTOs and JsonCodec SPI alone are also reusable by any other integration (e.g. a Kafka producer/consumer) that needs to (de)serialize TypeSafe payloads.

Two TypeSafeClient test doubles for unit-testing code that calls it without hitting the real API: RecordingTypeSafeClient (queue responses, record requests) and FailingTypeSafeClient (a decorator that fails every Nth call). Depends only on ...

MappingTypeSafeClient, a TypeSafeClient decorator that maps a record's @Noul/@Choice/@Score-annotated components into an EvaluateRequest and the response back into an instance of that same record, via reflection, so a caller gets a typed ...
