Bulk Download Details

After receiving your access token, you'll need to accept Addgene's data access license before retrieving the bulk download for the first time.

File Structure

The data is provided as JSON. JSON has the following properties you should be aware of:

  • It is encoded with UTF-8.
  • It isn't ordered, so the keys can appear in any order.
  • Whitespace/line breaks may vary.
  • Any array can contain zero or more items.
  • Fields inapplicable to a given item may be null.
  • All keys are included, even if they hold empty string or null values.

JSON parsers and libraries exist for almost every programming language. We recommend you use one.

* Principal Investigator/Head of Laboratory names are not included in the data.

File Versioning

Our JSON file follows a version format: majorVersion.minorVersion.

Changes in the majorVersion may require you to update your code, while minorVersion updates are generally backward-compatible. Specialized versions may have a suffix format (e.g., 1.0-XXX), while the main feed will have no suffix.
