Frequently Asked Questions

  • Yes, but you must have a premium subscription. Commercial use of the Password Generator API is not permitted on the free tier. See our pricing page to choose a plan that fits your needs.
  • Sign up for a free account to instantly get your API key, then pass it in the X-Api-Key header on every request. The documentation above includes ready-to-run examples in cURL, Python, JavaScript, Node.js, and more.
  • Your API requests will simply be denied once you hit your monthly quota — you will never be charged more than the plan you signed up for. To increase your quota, you can upgrade your plan any time on our pricing page.
  • The API responds with a standard HTTP status code and a JSON error message describing the problem. See our error codes reference for the full list of codes and how to resolve each one, or contact support if you need help.
  • Pass the length query parameter to the /v1/passwordgenerator endpoint to set the number of characters; if you omit it, a default length of 16 is used. See the full API documentation for details.
  • Yes, set the exclude_numbers and exclude_special_chars parameters to true to remove digits or special characters (!@#$%^&*()) from the output, though both are premium-only features available on a paid plan. By default both are false.
  • A successful request returns a JSON object with a single random_password field containing the generated password string, for example nYs43u5f1oGK9*g5. If a request fails, you instead receive an error.
  • It is ideal for creating strong, hard-to-guess passwords during account sign-up flows, resetting credentials, or seeding test data, and it pairs well with related tools like the Random User API and Random Word API for generating mock accounts.
