The @phala/cloud SDK uses Zod schemas for runtime validation of all API responses. Schemas are versioned — each API version has its own set of schemas.

​
Schema Validation

By default, every action validates the API response against the version-specific Zod schema. You can customize this: 
import { z } from "zod";

// Default: uses built-in schema
const user = await client.getCurrentUser();

// Custom schema: validate with your own Zod schema
const MySchema = z.object({ username: z.string() });
const user = await client.getCurrentUser({ schema: MySchema });

// No validation: returns raw response as unknown
const raw = await client.getCurrentUser({ schema: false });

Importing Schemas

All Zod schemas are exported from @phala/cloud: 
import {
  // v2026-01-21
  CvmInfoV20260121Schema,
  CvmInfoDetailV20260121Schema,
  PaginatedCvmInfosV20260121Schema,
  CurrentUserV20260121Schema,

  // v2025-10-28
  CvmInfoV20251028Schema,
  CvmDetailV20251028Schema,
  PaginatedCvmInfosV20251028Schema,
  CurrentUserV20251028Schema,
} from "@phala/cloud";
Use them for custom validation or to build derivative schemas: 
import { CvmInfoV20260121Schema } from "@phala/cloud";

// Pick only the fields you need
const MyCvmSchema = CvmInfoV20260121Schema.pick({
  id: true,
  name: true,
  status: true,
});

const cvm = await client.getCvmInfo({ id: "cvm-abc123" }, { schema: MyCvmSchema });
// cvm: { id: string; name: string; status: string }
