Just to clarify, are your requirements for:

- A C API?
- A stable C API?
- An ABI-stable C API?
- An API?
- A stable API?
- An ABI-stable API?

For most of these things, I’d be happy with a stable C++ API (ABI-stable within major releases, recompile - but nothing else - needed between), which could potentially be wrapped in a machine-generated C API for bindings in other languages.
