Get a Hokusai API Key
Every Hokusai integration starts with an API key. Create the key in the Hokusai web application, then expose it only to the local process or service that calls Hokusai.
1. Sign in or create an account
Open Hokusai API Keys. If you are not signed in, Hokusai will preserve the destination while you sign in or create an account.
You can use email and password, Google, or an Ethereum wallet. After authentication, continue to Settings → API Keys.
2. Create the key
Select Create API Key, optionally give it a descriptive name such as Local development, and select Create Key.
Copy the full key immediately. Hokusai shows it only once. If you lose it, create a new key or rotate the existing key.
3. Export the key
Set the key in the same shell that will start your coding agent or application:
export HOKUSAI_API_KEY=hk_live_your_key_here
Do not commit the value to source control. For deployed applications, store it in your platform's secrets manager.
4. Continue with your integration
The key is verified as part of the first doctor check or routing request. Continue with one of these paths:
Auth service operators
The admin-token API is intended for operators managing the authentication service, not for ordinary developer signup. See API Key Management for administrative creation, rotation, revocation, scopes, and organization keys.
