How to use H3

The public API of the H3 Core Library is defined in the file h3api.h. The functions defined in h3api.h adhere to Semantic Versioning.

The H3 API expects valid input. Behavior of the library may be undefined when given invalid input. Indexes should be validated with h3IsValid or h3UnidirectionalEdgeIsValid as appropriate.

You can find an example of using the H3 library in examples/index.c.
