Reference

This section is for precise lookup rather than sequential learning. Start with Quick Start or Workflows when you need an explanation of a concept.

How to use the reference

  • Check the format overview and individual format pages for capability coverage.
  • Use the Python API and its generated pages for names, signatures, and defaults.
  • Prefer per-call arguments; change the global configuration only for a policy that should affect later calls.
