+You can use the `--replay-proxy` flag to replay matched requests through a separate proxy (e.g., Burp Suite). This lets you route all traffic through one proxy (or direct) while only sending interesting results to your interception proxy:
+
+```bash
+$ sj automate -u https://petstore.swagger.io/v2/swagger.json -qi --replay-proxy http://127.0.0.1:8080
+```
+
+You can also combine it with `--proxy` to route scanning traffic through a different proxy while replaying matches to Burp:
+
+```bash
+$ sj automate -u https://petstore.swagger.io/v2/swagger.json -qi -p http://proxy:9090 --replay-proxy http://127.0.0.1:8080
+```
+
+You can also request verbose output to see the partial (or full) response:
+
+```bash
+$ sj automate -u https://petstore.swagger.io/v2/swagger.json -qi -p http://127.0.0.1:8080 -v
