The README opens with
An unofficial C++ client for TypeSafe AI, modeled on the official Python and JS SDKs.
- C++17, and works with exceptions and RTTI disabled: failures are Result values - Non-blocking: calls return a Pending , and client.pump() runs from your loop (blocking calls too) - Answer types are checked at compile time - Pluggable HTTP transport (libcurl by default, or your own) - Sends byte-identical requests to the official Python SDK (checked against the live API)
