+# Rate Limiting in VoltAgent
+
+This example demonstrates how to implement comprehensive rate limiting in VoltAgent agents, including different strategies, tool-specific limits, and monitoring hooks.
+
+## Features Demonstrated
+
+1. **Basic LLM Rate Limiting** - Enforce model request limits with error throwing
+2. **Delay Strategy** - Automatically wait when rate limits are exceeded
+3. **Tool-Specific Rate Limiting** - Set different limits for different tools
+4. **Tool Rate Limiting** - Focus on individual tool request constraints
+5. **Combined LLM + Tool Rate Limiting** - Apply limits at both agent and tool levels
+6. **Rate Limit Statistics** - Monitor and track rate limit usage
+7. **Hooks for Monitoring** - React to rate limit events with callbacks
+
+## Installation
+
+```bash
+cd examples/with-rate-limiting
+pnpm install
+```
+
+## Configuration Options
+
+### Basic Rate Limit Configuration
+
+```typescript
+const agent = new Agent({
+  name: "limited-agent",
+  model: google("gemini-2.0-flash-exp"),
+  instructions: "You are a helpful assistant.",
+  rateLimits: {
+    llm: {
+      maxRequestsPerMinute: 5,
+      strategy: "fixed_window", // or "sliding_window", "token_bucket", "leaky_bucket"
+      onExceeded: "throw", // or "delay"
+    },
+  },
+});
+```
+
+### Rate Limiting Strategies
+
+- **Fixed Window**: Simple per-minute counter reset
+- **Sliding Window**: More accurate time-based windowing
+- **Token Bucket**: Allows burst traffic while maintaining average rate
+- **Leaky Bucket**: Smooth request distribution over time
+
+## Hooks for Monitoring
+
+Hooks allow you to react to rate limit events with custom callbacks:
+
+```typescript
+const agent = new Agent({
+  name: "hooked-agent",
+  model: google("gemini-2.0-flash-exp"),
+  instructions: "You are a helpful assistant.",
+  rateLimits: {
+    llm: {
+      maxRequestsPerMinute: 3,
+      onExceeded: "delay",
+      onLimitExceeded: async (context) => {
+        console.warn(`⚠️ Rate limit exceeded for scope: ${context.scope}`);
+        console.warn(`  Remaining: ${context.stats.remaining}`);
+        console.warn(`  Reset at: ${context.stats.resetAt}`);
+      },
+    },
+    tools: {
+      search_tool: {
+        maxRequestsPerMinute: 2,
+        onExceeded: "delay",
+        onLimitExceeded: async (context) => {
+          console.warn(`⚠️ Search tool rate limit exceeded!`);
+          // Send alerts, log to monitoring systems, etc.
+        },
+      },
+    },
+  },
+});
+```
+
+### Hook Context Properties
+
+When a hook is triggered, the context object contains:
+
+- `scope` - The scope where limit was exceeded (e.g., "llm", "tool:search_tool")
+- `stats` - Rate limit statistics object with:
+  - `remaining` - Number of requests still available in current window
+  - `resetAt` - Timestamp when the rate limit window resets
+
+## Examples in Detail
+
+### Example 1: Basic LLM Rate Limiting
+
+Demonstrates enforcing a 3 requests-per-minute limit with error throwing. The 4th request will throw a `RateLimitExceededError` containing retry information.
+
+**Key Features:**
+
+- `maxRequestsPerMinute: 3` - Only 3 requests allowed per minute
+- `onExceeded: "throw"` - Immediately throws error when limit exceeded
+- Error includes `remaining` count and `resetAt` timestamp
+
+### Example 2: Delay Strategy
+
+Shows automatic waiting when limits are reached. The agent automatically delays the 3rd request until the rate limit window resets, providing a seamless experience.
+
+**Key Features:**
+
+- `maxRequestsPerMinute: 2` - Only 2 requests allowed per minute
+- `onExceeded: "delay"` - Automatically waits instead of failing
+- Transparent to the caller - request completes after waiting
+
+### Example 3: Tool-Specific Rate Limiting
+
+Sets different limits for different tools:
+
+- `search_tool`: 5 requests/minute
+- `calculator`: 10 requests/minute
+
+Each tool has independent rate limit counters.
+
+**Key Features:**
+
+- Multiple tools with different limits
+- Each tool tracked separately
+- `onExceeded: "throw"` for strict enforcement
+
+### Example 4: Tool Rate Limiting
+
+Focuses on limiting a specific tool (`search_tool` at 2 requests/minute). Useful when a particular tool has stricter API rate limits.
+
+**Key Features:**
+
+- Single tool limiting
+- `onExceeded: "throw"` strategy
+- Tests agent behavior with multiple search requests
+
+### Example 5: Combined LLM + Tool Rate Limiting
+
+Applies limits at both levels:
+
+- Global LLM: 5 requests/minute with delay
+- Individual tool: 3 requests/minute with delay
+
+The agent respects all configured limits.
+
+**Key Features:**
+
+- Both LLM and tool limits active
+- Both use `onExceeded: "delay"`
+- Demonstrates multi-level rate limiting
+
+### Example 6: Monitoring Rate Limit Statistics
+
+Demonstrates how to access and monitor rate limit state. Statistics are tracked internally and accessible through error properties when limits are exceeded.
+
+**Key Features:**
+
+- Rate limits are maintained internally
+- Statistics available in error objects
+- Useful for logging and monitoring
+
+### Example 7: Hooks for Rate Limit Monitoring ⭐ NEW
+
+Uses callback hooks to react to rate limit events in real-time:
+
+- `onLimitExceeded` - Called when a rate limit is exceeded
+
+This provides flexible, event-driven monitoring without blocking the agent flow.
+
+**Key Features:**
+
+- `maxRequestsPerMinute: 3` with 4 requests (triggers hook)
+- Hook logs scope, remaining count, and reset timestamp
+- Demonstrates hook triggering and context usage
+
+## Running Examples
+
+Edit `src/index.ts` and uncomment the examples you want to run in the `main()` function:
+
+```typescript
+async function main() {
+  console.log("🚀 VoltAgent Rate Limiting Examples\n");
+
+  try {
+    await example1_basicLLMRateLimit();
+    await example2_delayStrategy();
+    await example3_toolRateLimiting();
+    await example4_toolRateLimiting();
+    await example5_combinedLimits();
+    await example6_monitoringStats();
+    await example7_hooksForMonitoring();
+
+    console.log("\n✓ Examples ready!");
+  } catch (error) {
+    console.error("\n✗ Error:", error);
+  }
+}
+```
+
+Then run:
+
+```bash
+pnpm run dev
+```
+
+## Error Handling
+
+When using `onExceeded: "throw"`:
+
+```typescript
+try {
+  const response = await agent.generateText("What is AI?");
+} catch (error) {
+  if (error instanceof RateLimitExceededError) {
+    console.log(`Retry after ${error.retryAfter} seconds`);
+    console.log(`Remaining requests: ${error.stats.remaining}`);
+    console.log(`Reset at: ${error.stats.resetAt}`);
+  }
+}
+```
+
+When using `onExceeded: "delay"`:
+
+```typescript
+// The agent automatically waits for the rate limit window to reset
+const response = await agent.generateText("What is AI?");
+// Request completes transparently after waiting
+```
+
+## Best Practices
+
+1. **Choose Appropriate Limits**: Set realistic limits based on your API quotas
+2. **Monitor Hooks**: Use hooks to track rate limit violations and alert teams
+3. **Combine Strategies**: Use different strategies at different levels (LLM vs tools)
+4. **Plan for Bursts**: Token bucket strategy works well for bursty workloads
+5. **Log Rate Limit Events**: Keep audit trails of rate limit violations
+6. **Test Gracefully**: Verify behavior when limits are reached before production
+
+## Use Cases
+
+- **Cost Control**: Limit expensive LLM API calls to manage expenses
+- **API Quota Management**: Stay within provider rate limits and quotas
+- **Resource Protection**: Prevent tool overuse and API abuse
+- **Fair Usage**: Distribute resources fairly across multiple agents
+- **Compliance**: Ensure rate limits required by service agreements
+- **Graceful Degradation**: Choose between failing fast or queuing requests
