Server API

Budget Router

All admin-only interactions with LiteLLM budgets and customers are exposed via the tRPC router under budget.* procedures.

• budget.listCustomers – lists customers by calling the LiteLLM customer list endpoint.
• budget.getCustomerInfo – fetches customer details given { end_user_id }.
• budget.createBudget – creates a budget with { budget_id, max_budget, budget_duration? }.
• budget.assignBudget – assigns an existing budget via { user_id, budget_id }.
• budget.listBudgets – lists budgets from LiteLLM.
• budget.updateBudget – updates a budget's max_budget via { budget_id, max_budget }.

Every procedure:

• Uses Zod validation for its inputs and, where relevant, outputs.
• Requires an authenticated admin session enforced by the adminProcedure middleware in src/server/api/trpc.ts.
• Returns normalized, user-safe error messages using TRPCError.

Refer to src/server/api/routers/budget.ts for implementation details.
