  • Automatic Key Validation: Tests the provided key against the Vapi API endpoint to confirm it is active and functional.
  • Secure Credential Storage: Automatically saves the valid key to a .env file and updates .gitignore to prevent accidental exposure in version control.
  • Use Case: If you are building a voice AI agent with Vapi and receive 401 Unauthorized errors, use this skill to quickly obtain a valid key, verify it works, and store it securely so you can resume development.
