Online Directories Submission Service

I need to implement a feature that is called "Online Directories Submission". This is when a website URL is automatically submitted to multiple online directories for listing. This type of service has been on the marker for years and there are many existing websites that offer this service. Many sites claim they can submit your website URL and description to 100+ directories. This is usually done to improve domain ranking. I want to implement this feature for my website and allow customers to submit their website to multiple online listing directories automatically. I need bare minimum - a working engine. You do not need to worry about the design and etc. This will be done by other people after. Your job is to build the working core. I don't mind if you build it using AI. If you have experience working with this and know how to implement it, please reply to this job post with your offer.
