I want to get CPFP information out of a full node—that is, ancestorsize and ancestorfees—in order to calculate the necessary fee for either CPFP, or RBF if possible.
Can I get this information through an RPC without requesting the full mempool dump?
I need this to build tools for CPFP/RBF, that are connecting to full node via RPC. But I can only find the full mempool dump, which is inefficient for this. (I don't need the full dump for one transaction information).
