cosmos-sdk: How to get readable transactions of a block from API?

Summary

I cann’t get readable transactions of one block from API http://localhost:26657/block?height=3, because txs params is encoded data.

GET https://localhost:1317/blocks/3

{
    "jsonrpc": "2.0",
    "block": {
      ......................
      "data": {
        "txs": [
          "+wHwYl3uCnjqK1CUChSzAR1m0CdB0hEH42oUyDxRsnM5pRIlFiTeZCATlR1nIY5WzOSt1kaRXBpLJPJXfC4Xhj8LaWUYH8F4ThooCh8KBGh0dHASCTEwLjAuMC45NhoJbG9jYWxob3N0IMA+EgVOT0RFMSILCgRBSU9aEgMxMDASDwoJCgRBSU9aEgE1EMCaDBpqCibrWumHIQKQPb8sahooV/qJRP2ikxPxuSTFp+pcJ1HPTAXd1wWzCRJAQxAQn1254DoPTXQ/rsNsKJ/rNeenGPYufv5VcKVlcf9d8BHI8MBBWL+jSTgAavWYrDBHLaDP7ZAr0rDbp1ldbg=="

}

Problem Definition

On my web client, I need to get list transactions (ids or details) of one block? Did we have it?

Proposal

Can I get readable transactions of a block through RPC API?

Another solution I found is search txs: https://localhost:1317/txs?tx.height=3 but get error because of tags must be string when search tx https://github.com/cosmos/cosmos-sdk/blob/dbfaa4a514fd70297d4a415ce2b6b46b3f6836a0/client/tx/search.go#L174

So, I got an error

TxSearch: Response error: RPC error -32603 - Internal error: interface conversion: interface {} is string, not int64
