Copy cosmos.feegrant.v1beta1.Query/Allowance

Example:

Copy grpcurl -plaintext \ -d '{"grantee":"cosmos1..","granter":"cosmos1.."}' \ localhost:9090 \ cosmos.feegrant.v1beta1.Query/Allowance

Example Output:

Copy { "allowance": { "granter": "cosmos1..", "grantee": "cosmos1..", "allowance": {"@type":"/cosmos.feegrant.v1beta1.BasicAllowance","spendLimit":[{"denom":"stake","amount":"100"}]} } }
