Basic Usage

stac-validator --help
Usage: stac-validator [OPTIONS] STAC_FILE

Options:
  --core                   Validate core stac object only without extensions.
  --extensions             Validate extensions only.
  --links                  Additionally validate links. Only works with
                           default mode.
  --assets                 Additionally validate assets. Only works with
                           default mode.
  -c, --custom TEXT        Validate against a custom schema (local filepath or
                           remote schema).
  -r, --recursive          Recursively validate all related stac objects.
  -m, --max-depth INTEGER  Maximum depth to traverse when recursing. Omit this
                           argument to get full recursion. Ignored if
                           `recursive == False`.
  --collections            Validate /collections response.
  --item-collection        Validate item collection response. Can be combined
                           with --pages. Defaults to one page.
  --no-assets-urls         Disables the opening of href links when validating
                           assets (enabled by default).
  -p, --pages INTEGER      Maximum number of pages to validate via --item-
                           collection. Defaults to one page.
  -v, --verbose            Enables verbose output for recursive mode.
  --no_output              Do not print output to console.
  --log_file TEXT          Save full recursive output to log file (local
                           filepath).
  --version                Show the version and exit.
  --help                   Show this message and exit.
