In addition to the fixed-format data files that have been available for many years, PDG provides an API (Application Programming Interface) with three tools to access PDG data in machine-readable format, namely:

• a REST API and data downloading from pdgLive via "JSON" buttons,
• a Python API, and
• downloadable PDG database files in SQLite format.

NEW: With the present 2025 update, experimental access to the data from the Particle Listings was added in pdgLive (see new "JSON (beta)" buttons on Listings pages), Python API, and SQLite files.
For detailed documentation, see pdgapi.lbl.gov/doc.
