Open Access (OA) publications allow for anyone to access research information free of charge. It is difficult for researchers to discover which OA publications exist, and the price to publish. We designed and implemented a data-driven web app and API enabling researchers to discover relevant and reputable OA publications to maximize publishing impact. We aggregated price information and journal impact data. Our goal is to provide the OA community with the tools they need to separate legitimate OA publications from unethical publishers. We believe transparency in the market will produce downward price pressure, further lowering economic barriers to publishing.
