API Keys

This guide will help you create and manage API keys for the Writer API.

All actions are performed in AI Studio.

​

About API keys

The Writer API uses token authentication for API requests. API keys are used as tokens, which you pass in the Authorization header of your requests:

Authorization: Bearer <api-key>

​

API agents and API keys

Writer API keys are attached to AI Studio API agents.

API permissions and scopes are set at the agent level. Within an API-based agent, you can create multiple API keys that share the permissions of the agent. To create keys with different permissions, create multiple API agents.

​

1. From the AI Studio home page, click on Build an agent.
2. Select API as the agent type.
3. Click on the agent’s name to rename it to something description, and provide a short description of your agent to help you keep track of what it does.
