Open Settings → API Key to generate a personal Bearer key. A key lasts for 30 days, RexiMemo stores only hashes plus limited key metadata, and generating a new key immediately revokes the previous key and any client credentials linked to it. The complete main key is shown only when it is created.
When a new API key is generated, RexiMemo also shows a short one-time client login code. The code expires after 10 minutes and can be redeemed once by an API client at POST /api/v1/auth/login-code. The client receives its own bearer credential linked to the same API key, so you do not have to type the long main key into the client. Replacing or revoking the main API key also invalidates credentials created through its login code.
Send a bearer credential as Authorization: Bearer YOUR_KEY to /api/v1. The current endpoint list, request bodies, binary download behavior and experiment-specific capabilities are documented at /api/docs. Theme Creator and Flipnote Encoder API sections only appear when the authenticated account has the matching experiment access.
API credentials act as the account that created them. Keep them out of source repositories, screenshots, logs and shared client builds. Revoke the key immediately from Settings if it is exposed. API use is also subject to the API section of the Terms of Use.
