Below is my Strapi response from Postman. I want to filter the data using the URL with Filters parameter. The protocol is REST and I do not want to do inside the controller. How can I extract the contentTitle = California - Security Interest?

{
    "data": [
        {
            "id": 5,
            "contentTitle": "Truth in Lending Disclosure",
            "boldContentTitle": true,
            "securityInterestDetails": {
                "id": 8,
                "contentTitle": " All Security Interests",
                "contentDetails": [
                    {
                        "id": 1,
                        "locale": "en",
                        "contentTitle": "Default - Security Interest",
                        "state": {
                            "id": 24,
                            "name": "Default",
                            "abbreviation": null,
                            "slug": "default"
                        },
                        "contentDetails": {
                            "id": 18
                        },
                        "localizations": []
                    },
                    {
                        "id": 2,
                        "locale": "en",

                            "slug": "ca"
                        },
