+# Wallet Funds API Documentation
+
+## Overview
+
+The Wallet Funds API provides red packet functionality for the DysonNetwork platform, allowing users to create and distribute funds among multiple recipients with expiration and claiming mechanisms.
+
+## Authentication
+
+All endpoints require Bearer token authentication:
+
+```
+Authorization: Bearer {jwt_token}
+```
+
+## Data Types
+
+### Enums
+
+#### FundSplitType
+```typescript
+enum FundSplitType {
+  Even = 0,    // Equal distribution
+  Random = 1   // Lucky draw distribution
+}
+```
+
+#### FundStatus
+```typescript
+enum FundStatus {
+  Created = 0,           // Fund created, waiting for claims
+  PartiallyReceived = 1, // Some recipients claimed
+  FullyReceived = 2,     // All recipients claimed
+  Expired = 3,           // Fund expired, unclaimed amounts refunded
+  Refunded = 4           // Legacy status
+}
+```
+
+### Request/Response Models
+
+#### CreateFundRequest
+```typescript
+interface CreateFundRequest {
+  recipientAccountIds: string[];  // UUIDs of recipients
+  currency: string;               // e.g., "points", "golds"
+  totalAmount: number;            // Total amount to distribute
+  splitType: FundSplitType;       // Even or Random
+  message?: string;               // Optional message
+  expirationHours?: number;       // Optional: hours until expiration (default: 24)
+  pinCode: string;                // Required: 6-digit PIN code for security
+}
+```
+
+#### SnWalletFund
+```typescript
+interface SnWalletFund {
+  id: string;                     // UUID
+  currency: string;
+  totalAmount: number;
+  splitType: FundSplitType;
+  status: FundStatus;
+  message?: string;
+  creatorAccountId: string;       // UUID
+  creatorAccount: SnAccount;      // Creator account details (includes profile)
+  recipients: SnWalletFundRecipient[];
+  expiredAt: string;              // ISO 8601 timestamp
+  createdAt: string;              // ISO 8601 timestamp

+  recipientAccountId: string;     // UUID
+  recipientAccount: SnAccount;    // Recipient account details (includes profile)
+  amount: number;                 // Allocated amount

+  createdAt: string;              // ISO 8601 timestamp
+  updatedAt: string;              // ISO 8601 timestamp
+}
+```
+
+#### SnWalletTransaction
+```typescript
+interface SnWalletTransaction {
+  id: string;                     // UUID
+  payerWalletId?: string;         // UUID (null for system transfers)

+  "instance": "/api/wallets/funds"
+}
+```
+
+#### Insufficient Funds

+
+#### Fund Not Available

+```
+
+#### Already Claimed
+```json
+{
+  "type": "https://tools.ietf.org/html/rfc9110#section-15.5.1",
+  "title": "Bad Request",
+  "status": 400,
+  "detail": "You have already received this fund",
+  "instance": "/api/wallets/funds/550e8400-e29b-41d4-a716-446655440003/receive"
+}
+```
+
+## Rate Limiting
+
+- **Create Fund**: 10 requests per minute per user
+- **Get Funds**: 60 requests per minute per user
+- **Get Fund**: 60 requests per minute per user
+- **Receive Fund**: 30 requests per minute per user
+
+## Webhooks/Notifications
+
+The system integrates with the platform's notification system:
+
+- **Fund Created**: Creator receives confirmation
+- **Fund Claimed**: Creator receives notification when someone claims
+- **Fund Expired**: Creator receives refund notification
+

+# Multi-part File Upload API
+
+This document outlines the process for uploading large files in chunks using the multi-part upload API.
+
+## 1. Create an Upload Task
+
+To begin a file upload, you first need to create an upload task. This is done by sending a `POST` request to the `/api/files/upload/create` endpoint.
+
+**Endpoint:** `POST /api/files/upload/create`
+
+**Request Body:**
+
+```json
+{
+  "hash": "string (file hash, e.g., MD5 or SHA256)",
+  "file_name": "string",
+  "file_size": "long (in bytes)",
+  "content_type": "string (e.g., 'image/jpeg')",
+  "pool_id": "string (GUID, optional)",
+  "bundle_id": "string (GUID, optional)",
+  "encrypt_password": "string (optional)",
+  "expired_at": "string (ISO 8601 format, optional)",
+  "chunk_size": "long (in bytes, optional, defaults to 5MB)"
+}
+```
+
+**Response:**
+
+If a file with the same hash already exists, the server will return a `200 OK` with the following body:
+
+```json
+{
+  "file_exists": true,
+  "file": { ... (CloudFile object in snake_case) ... }
+}
+```
+
+If the file does not exist, the server will return a `200 OK` with a task ID and chunk information:
+
+```json
+{
+  "file_exists": false,
+  "task_id": "string",
+  "chunk_size": "long",
+  "chunks_count": "int"
+}
+```
+
+You will need the `task_id`, `chunk_size`, and `chunks_count` for the next steps.
+
+## 2. Upload File Chunks
+
+Once you have a `task_id`, you can start uploading the file in chunks. Each chunk is sent as a `POST` request with `multipart/form-data`.
+
+**Endpoint:** `POST /api/files/upload/chunk/{taskId}/{chunkIndex}`
+
+-   `taskId`: The ID of the upload task from the previous step.
+-   `chunkIndex`: The 0-based index of the chunk you are uploading.
+
+**Request Body:**
+
+The body of the request should be `multipart/form-data` with a single form field named `chunk` containing the binary data for that chunk.
+
+The size of each chunk should be equal to the `chunk_size` returned in the "Create Upload Task" step, except for the last chunk, which may be smaller.
+
+**Response:**
+
+A successful chunk upload will return a `200 OK` with an empty body.
+
+You should upload all chunks from `0` to `chunks_count - 1`.
+
+## 3. Complete the Upload
+
+After all chunks have been successfully uploaded, you must send a final request to complete the upload process. This will merge all the chunks into a single file and process it.
+
+**Endpoint:** `POST /api/files/upload/complete/{taskId}`
+
+-   `taskId`: The ID of the upload task.
+
+**Request Body:**
+
+The request body should be empty.
+
+**Response:**
+
+A successful request will return a `200 OK` with the `CloudFile` object for the newly uploaded file.
+
+```json
+{
+  ... (CloudFile object) ...
+}
+```
+
+If any chunks are missing or an error occurs during the merge process, the server will return a `400 Bad Request` with an error message.
