export TDENGINE_CLOUD_URL="<url>"
export TDENGINE_CLOUD_TOKEN="<token>"
set TDENGINE_CLOUD_URL=<url>
set TDENGINE_CLOUD_TOKEN=<token>
$env:TDENGINE_CLOUD_URL='<url>'
$env:TDENGINE_CLOUD_TOKEN='<token>'

Usage
The TDengine REST API is based on standard HTTP protocol and provides an easy way to access TDengine. As an example, the code below is to construct an HTTP request with the URL, the token and an SQL command and run it with the command line utility curl.
curl -L \
-d "select name, ntables, status from information_schema.ins_databases;" \
$TDENGINE_CLOUD_URL/rest/sql\?token=$TDENGINE_CLOUD_TOKEN
