Every request to the Darkbloom API requires an API key. You pass the key in the Authorization header as a Bearer token. Keys are prefixed with eigeninference- so they are easy to identify and rotate if they appear in logs or source control.

​
Getting an API key

1

Sign up at darkbloom.dev

Create an account at darkbloom.dev. Darkbloom uses Privy for authentication — you can sign in with email or a connected wallet.

Add credits

API calls are metered. Add credits from the Billing section before sending inference requests. Requests return 403 when your balance reaches zero.
Store your API key in an environment variable or secrets manager. Never commit it to source control or expose it in client-side code.

​
Sending the key

Include the key in the Authorization header on every request:
Use the OPENAI_API_KEY and OPENAI_BASE_URL environment variables when working with the OpenAI SDK. Many tools and scripts already read from these variables automatically.

​
Key management

You can create and revoke keys programmatically. Key creation and revocation require an active Privy session (interactive login) — API keys cannot be used to create or revoke other API keys.

Revoke a key

Pass the key you want to revoke in the request body as {"key": "eigeninference-..."}.
