+### Programmatic Rate Limits & Usage (API)
+
+You can query your current API rate limits and usage summary using your API key.
+
+Endpoint:
+
+```text
+GET /api/users/me/usage-limits
+```
+
+Authentication:
+
+- Include your API key in the `X-API-Key` header.
+
+Response (example):
+
+```json
+{
+  "success": true,
+  "rateLimit": {
+    "sync": { "isLimited": false, "limit": 10, "remaining": 10, "resetAt": "2025-09-08T22:51:55.999Z" },

+  "usage": {
+    "currentPeriodCost": 12.34,
+    "limit": 100,

+
+Example:
+
+```bash
+curl -X GET -H "X-API-Key: YOUR_API_KEY" -H "Content-Type: application/json" https://sim.ai/api/users/me/usage-limits
+```
+
+Notes:
+
+- `currentPeriodCost` reflects usage in the current billing period.
+- `limit` is derived from individual limits (Free/Pro) or pooled organization limits (Team/Enterprise).
+- `plan` is the highest-priority active plan associated with your user.

+title: External API
+description: Query workflow execution logs and set up webhooks for real-time notifications
+---
+
+import { Accordion, Accordions } from 'fumadocs-ui/components/accordion'
+import { Callout } from 'fumadocs-ui/components/callout'
+import { Tab, Tabs } from 'fumadocs-ui/components/tabs'

+
+Sim provides a comprehensive external API for querying workflow execution logs and setting up webhooks for real-time notifications when workflows complete.
+
+## Authentication
+
+All API requests require an API key passed in the `x-api-key` header:
+
+```bash
+curl -H "x-api-key: YOUR_API_KEY" \
+  https://sim.ai/api/v1/logs?workspaceId=YOUR_WORKSPACE_ID
+```
+
+You can generate API keys from your user settings in the Sim dashboard.
+
+## Logs API
+
+All API responses include information about your workflow execution limits and usage:
+
+```json
+"limits": {
+  "workflowExecutionRateLimit": {
+    "sync": {
+      "limit": 60,        // Max sync workflow executions per minute
+      "remaining": 58,    // Remaining sync workflow executions
+      "resetAt": "..."    // When the window resets
+    },
+    "async": {
+      "limit": 60,        // Max async workflow executions per minute
+      "remaining": 59,    // Remaining async workflow executions
+      "resetAt": "..."    // When the window resets
+    }
+  },
+  "usage": {
+    "currentPeriodCost": 1.234,  // Current billing period usage in USD
+    "limit": 10,                  // Usage limit in USD
+    "plan": "pro",                // Current subscription plan
+    "isExceeded": false           // Whether limit is exceeded
+  }
+}
+```
+
+**Note:** The rate limits in the response body are for workflow executions. The rate limits for calling this API endpoint are in the response headers (`X-RateLimit-*`).

+## Webhook Subscriptions
+
+Get real-time notifications when workflow executions complete. Webhooks are configured through the Sim UI in the workflow editor.
+
+### Configuration
+
+Webhooks can be configured for each workflow through the workflow editor UI. Click the webhook icon in the control bar to set up your webhook subscriptions.
+
+**Available Configuration Options:**
+- `url`: Your webhook endpoint URL
+- `secret`: Optional secret for HMAC signature verification
+- `includeFinalOutput`: Include the workflow's final output in the payload
+- `includeTraceSpans`: Include detailed execution trace spans
+- `includeRateLimits`: Include the workflow owner's rate limit information
+- `includeUsageData`: Include the workflow owner's usage and billing data
+- `levelFilter`: Array of log levels to receive (`info`, `error`)
+- `triggerFilter`: Array of trigger types to receive (`api`, `webhook`, `schedule`, `manual`, `chat`)
+- `active`: Enable/disable the webhook subscription
+
+### Webhook Payload
+
+When a workflow execution completes, Sim sends a POST request to your webhook URL:
+
+```json
+{
+  "id": "evt_123",
+  "type": "workflow.execution.completed",
+  "timestamp": 1735925767890,
+  "data": {
+    "workflowId": "wf_xyz789",
+    "executionId": "exec_def456",
+    "status": "success",
+    "level": "info",
+    "trigger": "api",
+    "startedAt": "2025-01-01T12:34:56.789Z",

+    "log": "/v1/logs/log_abc123",
+    "execution": "/v1/logs/executions/exec_def456"
+  }
+}
+```
+
+### Webhook Headers
+
+Each webhook request includes these headers:
+
+- `sim-event`: Event type (always `workflow.execution.completed`)
+- `sim-timestamp`: Unix timestamp in milliseconds
+- `sim-delivery-id`: Unique delivery ID for idempotency
+- `sim-signature`: HMAC-SHA256 signature for verification (if secret configured)
+- `Idempotency-Key`: Same as delivery ID for duplicate detection
+
+### Signature Verification
+
+If you configure a webhook secret, verify the signature to ensure the webhook is from Sim:
+
+<Tabs items={['Node.js', 'Python']}>
+  <Tab value="Node.js">
+    ```javascript
+    import crypto from 'crypto';
+
+    function verifyWebhookSignature(body, signature, secret) {

+      const timestamp = timestampPart.replace('t=', '');
+      const expectedSignature = signaturePart.replace('v1=', '');
+      
+      const signatureBase = `${timestamp}.${body}`;
+      const hmac = crypto.createHmac('sha256', secret);

+        timestamp = timestamp_part.replace('t=', '')
+        expected_signature = signature_part.replace('v1=', '')
+        
+        signature_base = f"{timestamp}.{body}"
+        computed_signature = hmac.new(
+            secret.encode(),

+  </Tab>
+</Tabs>
+
+### Retry Policy
+
+Failed webhook deliveries are retried with exponential backoff and jitter:
+
+- Maximum attempts: 5
+- Retry delays: 5 seconds, 15 seconds, 1 minute, 3 minutes, 10 minutes
+- Jitter: Up to 10% additional delay to prevent thundering herd
+- Only HTTP 5xx and 429 responses trigger retries
+- Deliveries timeout after 30 seconds
+
+<Callout type="info">
+  Webhook deliveries are processed asynchronously and don't affect workflow execution performance.
+</Callout>
+
+## Best Practices
+
+1. **Polling Strategy**: When polling for logs, use cursor-based pagination with `order=asc` and `startDate` to fetch new logs efficiently.
+
+2. **Webhook Security**: Always configure a webhook secret and verify signatures to ensure requests are from Sim.
+
+3. **Idempotency**: Use the `Idempotency-Key` header to detect and handle duplicate webhook deliveries.
+
+4. **Privacy**: By default, `finalOutput` and `traceSpans` are excluded from responses. Only enable these if you need the data and understand the privacy implications.
+
+5. **Rate Limiting**: Implement exponential backoff when you receive 429 responses. Check the `Retry-After` header for the recommended wait time.
+
+## Rate Limiting
+
+The API implements rate limiting to ensure fair usage:
+
+- **Free plan**: 10 requests per minute
+- **Pro plan**: 30 requests per minute
+- **Team plan**: 60 requests per minute
+- **Enterprise plan**: Custom limits
+
+Rate limit information is included in response headers:
+- `X-RateLimit-Limit`: Maximum requests per window
+- `X-RateLimit-Remaining`: Requests remaining in current window
+- `X-RateLimit-Reset`: ISO timestamp when the window resets
+
+## Example: Polling for New Logs
+
+```javascript
+let cursor = null;
+const workspaceId = 'YOUR_WORKSPACE_ID';
+const startDate = new Date().toISOString();
+
+async function pollLogs() {
+  const params = new URLSearchParams({
+    workspaceId,
+    startDate,
+    order: 'asc',
+    limit: '100'
+  });
+  
+  if (cursor) {
+    params.append('cursor', cursor);
+  }
+  
+  const response = await fetch(
+    `https://sim.ai/api/v1/logs?${params}`,
+    {
+      headers: {
+        'x-api-key': 'YOUR_API_KEY'
+      }
+    }
+  );
+  
+  if (response.ok) {
+    const data = await response.json();
+    
+    // Process new logs
+    for (const log of data.data) {
+      console.log(`New execution: ${log.executionId}`);
+    }
+    
+    // Update cursor for next poll
+    if (data.nextCursor) {
+      cursor = data.nextCursor;
+    }
+  }
+}
+
+// Poll every 30 seconds
+setInterval(pollLogs, 30000);
+```
+
