SSL Certificate Checker API - Ruby Gem

SSL Checker inspects a website's SSL certificate. It returns the certificate details plus derived signals — whether it is currently valid or expired, how many days until it expires, whether it expires soon, and whether it is self-signed.

Installation

Add this line to your application's Gemfile:

gem 'apiverve_sslchecker'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install apiverve_sslchecker

Getting Started

Get your API key at APIVerve

Basic Usage

require 'apiverve_sslchecker'

# Initialize the client
client = APIVerve::Sslchecker::Client.new(api_key: "YOUR_API_KEY")

# Make a request
response = client.execute({ domain: "ebay.com" })

# Print the response
puts response

Error Handling

begin
  response = client.execute({ domain: "ebay.com" })
  puts response["data"]
rescue APIVerve::Sslchecker::ValidationError => e
  puts "Validation error: #{e.errors.join(', ')}"
rescue APIVerve::Sslchecker::APIError => e
  puts "API error: #{e.message}"
  puts "Status code: #{e.status_code}"
end

Debug Mode

# Enable debug logging
client = APIVerve::Sslchecker::Client.new(
  api_key: "YOUR_API_KEY",
  debug: true
)
