 The [OpenGWAS database](https://gwas.mrcieu.ac.uk/) comprises over 50,000 curated, QC'd and harmonised complete GWAS summary datasets and can be queried using an API. See [here](https://api.opengwas.io/api/) for documentation on the API itself. This R package is a wrapper to make generic calls to the API, plus convenience functions for specific queries.
