#
# This workflow demonstrates using HttpRequestAction to call a REST API directly
# from the workflow without going through an AI agent first.
#
# HttpRequestAction allows workflows to:
# - Fetch data from external HTTP endpoints
# - Store the parsed response in workflow variables for later use
# - Add the response body to the conversation so a downstream agent can
#   answer questions based on it
#
# This sample fetches public metadata for the dotnet/runtime repository from
# the GitHub REST API (no authentication required) and uses an agent to
# answer follow-up questions about it.
#
# Example input:
# How many subscribers does the repository have?
#
