Returns active Locus Pro memberships so a person with more than one account can make an explicit selection. It does not approve the device. ## OpenAPI ````yaml /api-reference/openapi.json get /credits/mcp/oauth/device/tenants openapi: 3.1.0 info: title: Locus Pro API description: >- Production is live at https://api.paywithlocus.com/api. Stage remains available for evaluation and integration testing at https://api.stage.paywithlocus.com/api; credentials, balances, and tenant data are isolated by environment. Embedded prepaid credits over the Locus pay-per-use catalog. Money and top-up amounts use exact decimal strings (up to 6dp). Every burn requires an Idempotency-Key header. Management routes accept a tenant secret key or authorized dashboard session as shown per operation. Widget routes accept an end-user JWT alone; when a publishable key is present it must belong to the JWT's tenant. MCP uses OAuth 2.1 Authorization Code with PKCE by default and also accepts the explicitly documented tenant secret key, end-user JWT, or scoped agent connection compatibility credentials. Burns accept the execution credentials shown per operation. Publishable keys never authorize management or burns by themselves. version: 0.6.0 servers: - url: https://api.paywithlocus.com/api description: Production - url: https://api.stage.paywithlocus.com/api description: Stage — evaluation and integration testing security: - secretKey: [] tags: - name: Authentication description: Email-verified self-serve account creation and dashboard identity - name: Tenants description: Tenant profile, keys, and settings (dashboard session or secret key) - name: Workspace members description: Invite-only human workspace membership and role administration - name: Catalog description: Enable/disable APIs and set markups - name: Custom APIs description: >- Available when enabled for the workspace.
