+
+Shared building blocks for implementing clients that consume ZenStack's CRUD service. Used internally by [`@zenstackhq/fetch-client`](../fetch-client) and [`@zenstackhq/tanstack-query`](../tanstack-query), and useful when building your own custom client.

+# @zenstackhq/fetch-client
+
+A lightweight, type-safe fetch-based client for consuming ZenStack's RPC-style auto CRUD API. Provides the same model and operation surface as the server-side `ZenStackClient`, but issues HTTP requests instead of running queries locally.
+
+## Installation
+
+```bash
+npm install @zenstackhq/fetch-client
+```
+
+## Usage
+
+```typescript
+import { createClient } from '@zenstackhq/fetch-client';
+import { schema } from './schema';
+
+const client = createClient(schema, {
+    endpoint: 'https://example.com/api/model',
+});
+
+const users = await client.user.findMany({ where: { active: true } });
+const post = await client.post.create({ data: { title: 'Hello' } });
+
+const [user, newPost] = await client.$transaction([
+    { model: 'User', op: 'create', args: { data: { email: 'alice@example.com' } } },
+    { model: 'Post', op: 'create', args: { data: { title: 'Hello' } } },
+]);
+```

+        where: { published: true },
+        include: { author: true },
+    });
+
