Hi @gicu
If you have a Microsoft tenant, you can purchase the Power BI Embedded A sku (A1 being the cheapest and lowest capacity, and A6 the highest) via the Azure portal. This resource can be pause at anytime and you will only be charged by the time you use it and depending on how many page render by your end users. Otherwise, go for higher subscription like EM or P, but they are more expensive.
This is a useful site to start and have a good understanding of the different licenses. Remember, the keyword in this article is Premium (EM, P) vs. Azure (A) capacities.

Good luck,
