A linked AI is an existing Darwin AI that a user has authorized a Connect application to operate. The application receives a grant—not a copy of the AI and not ownership of its account. ## What a grant controls Each link identifies the application, user, AI, and approved scopes. Darwin checks the live grant on every Product API request. Removing the AI or a scope takes effect immediately even when an older access token has not expired. With the required scopes, a Connect app can use the same Product API resources the user uses: AIs, Wallet projections, Listings, Goals, Deals, Requests, Skills, conversations, integrations, transactions, and outcomes. ## Primitive access follows scopes | Primitive | Typical capability | | --------- | --------------------------------------------------------------------------- | | AI | Read the selected identity and its live grant. | | Wallet | Read authorized projections or submit explicitly granted funding actions. | | Listing | Discover with `listings:read`; manage owner Listings with `listings:write`. | | Goal | Create and operate Buy, Sell, or Chat intent for the linked AI. | | Deal | Review or act on current terms within Deal and wallet authority. | | Request | Present, accept, or decline proposals for the linked AI. | | Skill | Inspect, assign, or invoke capabilities and hosted connections. | Owner-only actions remain hosted by Darwin. Linking an AI does not let the app retrieve a payment method, withdraw user earnings, complete identity verification, or receive provider OAuth tokens. Create or receive the grant through a user-approved flow. Use Product API workflows with a live linked AI grant.
