What is API Key? — NodeOps Glossary
API Key — An API key is a secret token that identifies and authorizes your app when communicating with a service. It acts as a password for programs, not people. The key verifies your account and enables access to authorized data and services. If someone else obtains your key, they could use your account, potentially incurring costs or triggering rate limits. Always protect your API keys using environment variables and secret management systems.
