                        JSON key to extract the blockheight information, e.g., 'result.sync_info.latest_block_height'. The script will check if the blockheight at
                        this path is increasing.
  --dry-run             Executes a dry run without making actual HTTP requests. Default is False.

This script provides various options to check the HTTP status of URLs.

Usage examples:
  1. Basic usage:
        pawns http https://example.com

  2. Verbose mode:
        pawns http https://example.com -v

  3. Using custom headers and POST method:
        pawns http https://example.com -m POST --headers '{"Content-Type": "application/json"}' --data '{"param": "value"}'

  4. Ignoring SSL verification and setting a custom timeout:
        pawns http https://example.com --ignore-ssl True --timeout 5

  5. Checking with specific success criteria and logical operator:
        pawns http https://example.com --success 'status_code==200' 'response_time<2' --logical-operator and

  6. Running with a custom config file and interval:
        pawns http https://example.com -c http_config.ini -i 3

    http_config.ini
    [default]
    success = status_code==200
    slack_url =
    interval = 3
    method = get
    ; data = sdsd
    data = {"sdsd": "sd222sd"}

    [post]
    url = http://httpbin.org/post
    method = post

    [http_200_ok]
    url = http://httpbin.org/status/200
    success = status_code==200

    [http_300_ok_and_2ms_time]
    url = http://httpbin.org/status/300
    success = ['status_code==300', 'response_time<0.02']

    [http_400_ok]
    url = http://httpbin.org/status/400
    success = ["status_code==400"]


  7. Setting maximum workers and stack limit:
        pawns http https://example.com -w 5 --stack-limit 10

  8. Dry run without actual HTTP request:
        pawns http https://example.com --dry-run

  9. Sending notifications to a Slack URL on failure:
        pawns http https://example.com --slack-url 'https://hooks.slack.com/services/...'

 10. Checking blockheight increase:
        pawns http http://test-node-01:26657/status --blockheight-key "result.sync_info.latest_block_height" -i 5

Officially supports Python 3.9+.
