On-device reactions
Oneira's expressive reactions run on the device, so its face can respond without relying on a cloud request.

How to connect a custom API to an AI device safely: scoped credentials, read-only first, human approval for writes, and how Oneira applies your permissions.
Product status
Working today means the expressive face has been demonstrated on a real Oneira device.
Connected beta features require the Oneira app, internet access, a compatible service, and permissions you approve. They can change and may not work with every service.
The short answer

Oneira Dream Big+
Small enough to look playful. Built with a dual AI chip, OLED screen, and 1K camera, plus optional connected experiences you control.
Each $80 Founding Unit includes one Oneira device with a dual AI chip, OLED screen, and 1K camera, plus the selected color and included eye set. Only the final 1K camera module may change before fulfillment. Optional connected services, separate accounts, usage, and third-party fees are not included.

See included hardwareOptional compatible connected services can extend Oneira when you choose. Setup, permissions, internet access, service terms, accounts, usage, and fees remain separate. Connected experiences work only with compatible services the owner deliberately configures. Oneira does not connect automatically to every service.

Understand the agent pathA simple flow
Pick one endpoint and one job it should do
Issue a dedicated key with the minimum access
Prove reads first, then gate writes behind approval
The concept
A custom API connection points an AI device at an interface you control — your own service, a home server, an internal tool — instead of a packaged integration someone else designed. You decide which endpoints exist, what they accept, and what they return.
That control is the appeal and the responsibility. Nothing stands between the device and your service except the boundaries you design, which is why the safety patterns below matter more here than anywhere else.
Credentials
Authenticate every call, and never with a credential that can do more than the connection needs. A dedicated key with least-privilege scope means a leaked or misused credential is a contained problem instead of an account takeover.
Keep the key revocable and specific to this one connection, so you can cut an integration off without touching anything else. If your API distinguishes read scopes from write scopes, use that distinction — it is the cheapest security boundary available.
Sequencing
Start with one read-only endpoint and one small task, and confirm the round trip does what you expect before adding anything. A read that fails or returns something odd costs you nothing; it just teaches you about the connection.
Writes are different. Any call that changes state — posts, sends, deletes, purchases — should stay behind an explicit human approval, at least until the integration has a history you have reviewed. Automation can propose; you approve.
On Oneira
Custom API connections ship on Oneira today, and the published pattern is the same as every connection: you configure the service, authenticate with your own accounts, and grant specific permissions in the Oneira app, which routes requests only where you pointed them.
The accounts and any fees behind your API are yours, and a service name is never an automatic live connection. Endpoint-level configuration details beyond this pattern are not published in this guide.

Questions, answered
Any web API you control or are authorized to use — your own service, an internal tool, a third-party API you hold a key for. The connection is custom because you define what it exposes.
Because reads prove the whole path — authentication, routing, formatting — with nothing at stake. Once the connection has a track record, add writes one at a time behind human approval.
The app routes requests only to services you deliberately configured, with the permissions you granted. Scoping the credential itself adds a second wall on your side of the API.
You do, on your own accounts. No Oneira subscription is required for the core product; hosting, third-party API plans, and usage fees behind your connections stay yours.
This guide teaches the pattern — connect, authenticate, grant specific permissions, test small — because per-screen steps are not published here. Check current Oneira documentation when you set up a real connection.
