Request Unit (RU)
eth_getUncleCountByBlockNumberDifferent types of RPC queries consume different levels of BlockPI Network resources. Request Unit is a basic charge unit to calculate the usage of the network. This design will provide a fair and transparent experience for every developer and user. The following table shows the RU pricing of each method.
If you need to access the data from earlier blocks, you can open the Archive Model, which allows users to access all the historical data of the blockchain. This function is available for Klaytn and will be soon on the Polygon.
Archive mode will route the requests to archive nodes of the blockchain. Since running an archive node requires huge storage, the RU consumption will increase by 30%. And it typically takes a longer time to process due to the huge amount of data. So we recommend you open Archive Mode only when it’s necessary.
