• RESTFul API

<light_clinet_address>/cosmwasm/wasm/v1/contract/<contract_address>/smart/<JSON_formed_message_with_base64>

ex)

How to Organize a Query Message #

You may check <contract>/src/msg.rs of each contract.
Here is an example. Query messages are defined as below:

#[derive(Serialize, Deserialize, Clone, Debug, PartialEq, JsonSchema)]
#[serde(rename_all = "snake_case")]
pub enum QueryMsg {
    Balance { address: <Addr> },
    ...
}

This is one of the messages

Balance { address: <Addr> }

You may change it into snake case and add within {} as like below:

{"balance": {"address": "<Addr>"}}

Addr is a type, which is bech32-encoded address terra prefixed.
Here is an example:

{"balance": {"address": "terra1wxe503thjmapngtnyqarxrc4jy80vf800vf0cy"}}

This rule also can be applied to other messages, so you can utilize this guide as a reference for your practice.
