# RPC/LCD API

{% hint style="warning" %}
The documentation is designed for Liker Land and LikeCoin v2. For information on [3ook.com](https://3ook.com/) and LikeCoin v3, please visit [docs.3ook.com](https://docs.3ook.com) and [dao.like.co](https://dao.like.co/).
{% endhint %}

## Public RPC/LCD Endpoint

### Testnet

Please refer to `Current testnet` to get the latest chain ID, RPC, LCD and explorer for testnet

<https://github.com/likecoin/testnets>

### Mainnet

Please refer to this Github repo to get the latest chain ID, RPC, LCD and explorer for testnet

## RPC/LCD API

Since LikeCoin chain is based on Cosmos SDK, you may refer to the Cosmos SDK documents for most of the API:

<https://v1.cosmos.network/rpc/v0.42.6>

### GET /auth/accounts/{address}

Returns the information about the account.

Some commonly used fields:

`response.result.value.coins` (`[{amount: string, denom: string}]`): the balance of the account. `response.result.value.account_number` (`string`): the account number, which is needed when signing transactions. `response.result.value.sequence` (`string`): the sequence for replay protection, which is needed when signing transactions.

Example:&#x20;

<https://mainnet-node.like.co/auth/accounts/cosmos1mnyn7x24xj6vraxeeq56dfkxa009tvhgknhm04>

```
{
  "height": "574791",
  "result": {
    "type": "cosmos-sdk/Account",
    "value": {
      "address": "cosmos1mnyn7x24xj6vraxeeq56dfkxa009tvhgknhm04",
      "coins": [
        {
          "denom": "nanolike",
          "amount": "10000000000"
        }
      ],
      "public_key": null,
      "account_number": "21",
      "sequence": "0"
    }
  }
}
```

### GET /txs/{hash}

Fetch the transaction information.

A transaction may contain multiple messages, and if any of them failed during execution, the whole transaction fails without any state change, i.e. previous messages will be rollbacked.

User can check if the whole transaction succeeded by checking if the last object in `response.logs` shows `success: true` or not.

Example:&#x20;

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.v2.like.co/developer/likecoin-chain-api/rpc-api.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
