What is API Key Validator Tool?

The API Key Validator Tool lets you test the validity of API keys, tokens, or secrets for popular platforms (like Slack, GitHub, AWS, Stripe, etc.) in a safe and private way. Keys are never stored. It’s built for security testers, bug bounty hunters, and developers who want to check credentials quickly.

How to Use?

  1. Select the service you want to check (e.g. Slack, GitHub).
  2. Paste your API key, token, or secret in the field provided.
  3. Click Validate. You’ll get a real-time status—valid or invalid—plus context if available.
  4. We never log, save, or share your keys.

Use-cases:

  • Testing credentials shared in bug bounties or pentests
  • Checking if a found secret is active or revoked
  • Demo or educational testing (NEVER use on keys you don’t own)
