client.billing

This is the TypeScript interface. See client setup and behavior.

interface ClientSurface {
readonly billing: {
    get(): Promise<import("./types.js").BillingStatus>;
    usage(input?: {
        readonly cursor?: string;
    }): Promise<import("./types.js").BillingUsage>;
    activateTrial(input: {
        readonly policyVersion: "2026-09-12";
        readonly acceptsDeletion?: boolean;
    }): Promise<void>;
    checkout(input: {
        readonly idempotencyKey: string;
        readonly purchase: "credits_20" | "credits_50" | "credits_100" | "production";
        readonly acceptsDeletion?: boolean;
        readonly policyVersion: "2026-09-12";
    }): Promise<{
        readonly url: string | null;
    }>;
    portal(): Promise<{
        readonly url: string | null;
    }>;
    updateAutoRecharge(input: import("./types.js").BillingAutoRecharge): Promise<void>;
};
}
