Around September, I made a mini-program. Through Xianyu's traffic monetization, I successfully activated traffic monetization yesterday, but no one visits it, and I don't know how to promote it. After promoting it, how do I maintain a balance between revenue and expenses [because the API is paid]!

This is my mini-program QR code: 
Not counting server costs [the server also hosts a website, ignore that], the costs are as follows,
The homepage API is free, image watermark removal 0.15/time, video watermark removal 0.1/time, smudge watermark removal 0.15/time, ID photo generation 0.1/time, video reverse prompt words 0.1/time, smart cutout 0.025/time, image pixelation free
How do I promote it so people come, and then make money?
