API Keys and Credentials

Think of an API key as a password that one service uses to confirm your identity to another service. Unlike a regular login, it does not expire every time you close a browser. It stays active until you manually revoke or regenerate it.

To create your Anthropic API key, follow these steps:

• Go to Anthropic Console and sign in or create an account;
• Navigate to API Keys in the left menu under Manage;
• Click Create Key, give it a clear name and click Add;
• Copy the key immediately, Anthropic will not show it again;
• Store it in a secure note or password manager right away.

Relevant services are introduced as needed, along with instructions for generating API keys. The process is always the same:

• Sign in to the service;
• Navigate to Settings or API in the dashboard;
• Create a new key, give it a clear name and copy it immediately;
• Store it securely.

API usage is charged per token, roughly corresponding to the amount of input and output text. For typical tasks, costs are very low, often just a few cents per run. You will need to add a payment method, and you can set a monthly spending limit to avoid unexpected charges.
