Hello, World!

Thanks for your interest in the PharmGKB API.

It is a RESTful interface that serves JSON representations of all our data, including our annotations (e.g. dosing guidelines, pathways, clinical annotations) and reference objects (e.g. genes, chemicals, variants).

We would love to get feedback on what we have so far, as well as hear about what you'd like to do with our API.

You're welcome to take a look and try things out. The Swagger documentation would be a good place to start.

While the endpoints are pretty stable, the parameters and responses may change at any time while we are developing it. Please keep an eye on the ClinPGx Blog for an announcement of the final, stable API. The final release will also be noted in the documentation.
