Import & Export API

Use the Public API to export or update data that you have saved to W&B.

Before using this API, you'll want to log data from your script โ€” check the Quickstart for more details.

You might use the Public API to

  • update metadata or metrics for an experiment after it has been completed,
  • pull down your results as a dataframe for post-hoc analysis in a Jupyter notebook, or
  • check your saved model artifacts for those tagged as ready-to-deploy.

For more on using the Public API, check out our guide.
