+#### Feature toggles
+
+Selected features can be switched on and off at runtime through the admin server, without
+restarting the node. Each toggle shares the atomic state of its startup flag, so toggling it
+overrides that flag for the running process. When a feature is disabled its API responds with
+`503 Service Unavailable` and a `Retry-After` header.
+
+The following features are exposed:
+
+|   Feature    |     Backing flag      |                 Description                 |
+|--------------|-----------------------|---------------------------------------------|
+| `apilogs`    | `--enable-api-logs`   | API request logging                         |
+| `txpool-api` | `--api-enable-txpool` | Transaction pool API endpoints              |
+| `pprof`      | `--pprof`             | go-pprof handlers served at `/debug/pprof/` |
+
+List the state of all features via a GET request to /admin/features.
+
+```shell
+curl http://localhost:2113/admin/features
+```
+
+```json
+[
+    {"name": "apilogs", "enabled": false},
+    {"name": "pprof", "enabled": false},
+    {"name": "txpool-api", "enabled": true}
+]
+```
+
+Retrieve a single feature's state via a GET request to /admin/features/{name}.
+
+```shell
+curl http://localhost:2113/admin/features/pprof
+```
+
+Toggle a feature via a POST request to /admin/features/{name}. The optional `ttlSeconds` field
+(clamped to `0`–`3600`, `0` meaning no expiry) only takes effect when enabling a feature; the
+feature auto-disables after the TTL elapses.
+
+```shell
+curl -X POST -H "Content-Type: application/json" -d '{"enabled": true, "ttlSeconds": 300}' http://localhost:2113/admin/features/pprof
+```
+
+```json
+{
+    "enabled": true,
+    "ttlSeconds": 300
+}
+```
+
+- **Note**: `GET`/`POST /admin/apilogs` is kept as a deprecated alias for the `apilogs` feature.
+  It returns a `Deprecation` header pointing at `/admin/features/apilogs`; use the unified
+  `/admin/features` endpoints instead.
+
 #### Health
 
 Retrieve the node health infomation via a GET request to /admin/health.
