# Nimiq JSON-RPC Client Library for Gleam
[](https://hex.pm/packages/nimiq_rpc)
[](https://hexdocs.pm/nimiq_rpc/)
> **Important:**<br>
> This library requires Gleam v1.9, as it uses a Github dependency.
## Installation
```sh
gleam add nimiq_rpc
```
## Usage
First, create a client instance:
```gleam
import nimiq_rpc
pub fn main() {
let client = nimiq_rpc.client("http://localhost:8648")
// To add authentication information, use this function:
let client = nimiq_rpc.client_with_auth(
"http://localhost:8648",
"username",
"password",
)
}
```
Each RPC method has its own typed method in this library. The methods are ordered by dispatcher, just like they are in the Rust source code (but your editor's auto-import should help you resolve each method name you want to use). The name of each method is the `snake-case` version of the `camelCase` method name.
```gleam
import nimiq_rpc/consensus
import nimiq_rpc/blockchain
pub fn main() {
// ...
let assert Ok(has_consensus) = client |> consensus.is_consensus_established()
io.debug(has_consensus) // True or False
let assert Ok(number) = client |> blockchain.get_block_number()
io.debug(number) // For example 13424115
}
```
