+# Nylas Grants Examples
+
+This directory contains examples demonstrating how to work with grants using the Nylas Node.js SDK. Grants represent authenticated connections between your application and email/calendar providers like Gmail, Outlook, Yahoo, and others.
+
+## What are Grants?
+
+In the Nylas API, a **Grant** represents an authenticated connection to a user's email or calendar account. Each grant contains:
+
+- **Authentication details** - OAuth tokens and provider information
+- **Scope permissions** - What data your app can access (email, calendar, contacts, etc.)
+- **Account metadata** - Email address, provider type, creation/update timestamps
+- **Status information** - Whether the grant is valid or needs re-authentication
+
+## Examples Overview
+
+The `grants.ts` file demonstrates comprehensive grant management including:
+
+### 📋 **Basic Operations**
+- **List all grants** - Retrieve all authenticated accounts
+- **Fetch specific grant** - Get detailed information about a single grant
+- **Pagination** - Handle large numbers of grants efficiently
+
+### 🔄 **Sorting & Filtering**
+- **Sort by creation date** - See newest or oldest grants first
+- **Sort by update date** - Find recently modified grants
+- **Filter by provider** - Show only Gmail, Outlook, etc.
+- **Filter by status** - Find valid, invalid, or expired grants
+- **Filter by date range** - Grants created in specific time periods
+
+### 🎯 **Advanced Features**
+- **Multiple filters** - Combine provider, status, and date filters
+- **Client-side grouping** - Organize grants by provider or other criteria
+- **Scope analysis** - Find grants with specific permissions
+- **Rate limit monitoring** - Track API usage limits
+
+## Quick Start
+
+### 1. Set up environment
+Create a `.env` file in the `examples` directory:
+```bash
+NYLAS_API_KEY=your_api_key_here
+NYLAS_API_URI=https://api.us.nylas.com  # Optional: defaults to US API
+```
+
+### 2. Install dependencies
+```bash
+cd examples
+npm install
+```
+
+### 3. Run the example
+```bash
+# Using ts-node (recommended for development)
+npx ts-node grants/grants.ts
+
+# Or compile and run
+npm run build
+node dist/grants/grants.js
+```
+
+## Example Functions
+
+### Basic Listing
+```typescript
+// List all grants
+const grants = await nylas.grants.list();
+
+// List with pagination
+const grants = await nylas.grants.list({
+  queryParams: {
+    limit: 10,
+    offset: 0,
+  },
+});
+```
+
+### Sorting
+```typescript
+// Sort by creation date (newest first)
+const grants = await nylas.grants.list({
+  queryParams: {
+    sortBy: 'created_at',
+    orderBy: 'desc',
+  },
+});
+
+// Sort by update date (most recently updated first)
+const grants = await nylas.grants.list({
+  queryParams: {
+    sortBy: 'updated_at',
+    orderBy: 'desc',
+  },
+});
+```
+
+### Filtering
+```typescript
+// Filter by provider
+const gmailGrants = await nylas.grants.list({
+  queryParams: {
+    provider: 'google',
+  },
+});
+
+// Filter by status
+const validGrants = await nylas.grants.list({
+  queryParams: {
+    grantStatus: 'valid',
+  },
+});
+
+// Filter by date range (last 30 days)
+const thirtyDaysAgo = Math.floor((Date.now() - (30 * 24 * 60 * 60 * 1000)) / 1000);
+const recentGrants = await nylas.grants.list({
+  queryParams: {
+    since: thirtyDaysAgo,
+  },
+});
+```
+
+### Fetching Individual Grants
+```typescript
+// Fetch a specific grant by ID
+const grant = await nylas.grants.find({
+  grantId: 'grant-id-here',
+});
+
+console.log(`Grant for ${grant.data.email} (${grant.data.provider})`);
+console.log(`Scopes: ${grant.data.scope.join(', ')}`);
+console.log(`Status: ${grant.data.grantStatus}`);
+```
+
+## Grant Object Properties
+
+Each grant object contains the following key properties:
+
+```typescript
+interface Grant {
+  id: string;                    // Unique grant identifier
+  provider: string;              // 'google', 'microsoft', 'yahoo', etc.
+  email?: string;                // Associated email address
+  name?: string;                 // User's display name
+  grantStatus?: string;          // 'valid', 'invalid', 'expired'
+  scope: string[];               // Permissions: ['email', 'calendar', 'contacts']
+  createdAt: number;             // Unix timestamp
+  updatedAt?: number;            // Unix timestamp of last update
+  providerUserId?: string;       // Provider's internal user ID
+  ip?: string;                   // IP address during authentication
+  userAgent?: string;            // Browser/client used for auth
+  settings?: Record<string, unknown>; // Provider-specific settings
+}
+```
+
+## Available Query Parameters
+
+When listing grants, you can use these parameters:
+
+- **`limit`** (number) - Maximum results to return (default: 10, max: 200)
+- **`offset`** (number) - Skip this many results for pagination
+- **`sortBy`** - Sort field: `'created_at'` or `'updated_at'`
+- **`orderBy`** - Sort direction: `'asc'` or `'desc'`
+- **`since`** (number) - Unix timestamp to filter grants created after
+- **`before`** (number) - Unix timestamp to filter grants created before
+- **`email`** (string) - Filter by email address
+- **`grantStatus`** (string) - Filter by status: `'valid'`, `'invalid'`, etc.
+- **`ip`** (string) - Filter by IP address
+- **`provider`** (string) - Filter by provider: `'google'`, `'microsoft'`, etc.
+
+## Common Use Cases
+
+### 1. **Health Check Dashboard**
+```typescript
+// Get overview of all grants and their status
+const allGrants = await nylas.grants.list();
+const grantsByStatus = allGrants.data.reduce((acc, grant) => {
+  const status = grant.grantStatus || 'valid';
+  acc[status] = (acc[status] || 0) + 1;
+  return acc;
+}, {});
+console.log('Grant Status Overview:', grantsByStatus);
+```
+
+### 2. **Find Grants Needing Re-authentication**
+```typescript
+// Find invalid or expired grants
+const invalidGrants = await nylas.grants.list({
+  queryParams: {
+    grantStatus: 'invalid',
+  },
+});
+console.log(`${invalidGrants.data.length} grants need re-authentication`);
+```
+
+### 3. **Provider Distribution Analysis**
+```typescript
+// See which providers your users prefer
+const grants = await nylas.grants.list();
+const providerCounts = grants.data.reduce((acc, grant) => {
+  acc[grant.provider] = (acc[grant.provider] || 0) + 1;
+  return acc;
+}, {});
+console.log('Provider Distribution:', providerCounts);
+```
+
+### 4. **Recent Activity Monitoring**
+```typescript
+// Find grants created or updated in the last week
+const weekAgo = Math.floor((Date.now() - (7 * 24 * 60 * 60 * 1000)) / 1000);
+const recentActivity = await nylas.grants.list({
+  queryParams: {
+    since: weekAgo,
+    sortBy: 'created_at',
+    orderBy: 'desc',
+  },
+});
+```
+
+## Rate Limiting
+
+The Nylas API includes rate limiting. You can monitor your usage:
+
+```typescript
+const response = await nylas.grants.list();
+if (response.rawHeaders) {
+  const limit = response.rawHeaders['x-rate-limit-limit'];
+  const remaining = response.rawHeaders['x-rate-limit-remaining'];
+  console.log(`Rate Limit: ${remaining}/${limit} requests remaining`);
+}
+```
+
+## Error Handling
+
+Always wrap grant operations in try-catch blocks:
+
+```typescript
+try {
+  const grants = await nylas.grants.list();
+  // Process grants...
+} catch (error) {
+  if (error.status === 401) {
+    console.error('Invalid API key');
+  } else if (error.status === 429) {
+    console.error('Rate limit exceeded');
+  } else {
+    console.error('Error listing grants:', error);
+  }
+}
+```
+
+## Next Steps
+
+After exploring grants, you might want to:
+
+1. **Use grants to access data** - Use grant IDs to list messages, events, or contacts
+2. **Monitor grant health** - Set up automated checks for invalid grants
+3. **Implement re-authentication** - Handle expired grants gracefully
+4. **Build user dashboards** - Show users their connected accounts
