+# Rate Limiting
+
+ChainForge enforces rate limits to ensure API service availability, prevent abuse, and provide fair resource distribution.
+
+## Granularity and Keys
+
+Rate limiting key selection varies based on request authentication status:
+
+1. **Organization-based Rate Limiting**:
+   - If the request is authenticated with an API key containing an organization ID (`orgId`) set by `ApiKeyGuard` (making `request.org` present), the rate limiter buckets request counts by:
+     `org:<orgId>`
+   - This ensures that different organizations do not share rate limit quotas, preventing one organization's usage or DDoS attacks from blocking another.
+
+2. **IP-based Rate Limiting (Fallback)**:
+   - If the request is unauthenticated or has no associated organization ID, the rate limiter falls back to keying by the caller's IP address:
+     `req.ips[0]` or `req.ip` or `anonymous`/`unknown`
+
+## Guards and Middleware
+
+Rate limiting is implemented at two levels:
+
+- **Express Middleware (`createRateLimiter`)**:
+  - Registered globally to rate limit unauthenticated and verification requests.
+  - Dynamically retrieves `orgId` from the database if an `x-api-key` is supplied to ensure organization-specific limit thresholds are respected.
+  
+- **NestJS Guard (`AdaptiveRateLimitGuard`)**:
+  - Global NestJS guard that provides adaptive rate limiting using Redis sliding windows.
+  - Intercepts requests after `ApiKeyGuard` has run, extracting `(request as any).org` to determine the rate limiting key.
