What are the technical requirements to sell data on Quandl?

The technical requirements are minimal, but it is very important that you create, document, update and maintain the actual data by yourself, at a professional standard of quality.

You must be able to send data to us either via FTP or by using our proprietary upload tools. Or you need to make data available via FTP, API or a shared database. Part of Quandl’s core value to vendors is that we have flexible and robust data ingestion tools. We will work with you to identify and implement the best and most efficient data update process.
