# Getting Started with Neynar Go SDK

> Easily call Neynar APIs with our Go SDK

<Info>
  This tutorial uses the [Neynar Go SDK](https://github.com/neynarxyz/go-sdk)
</Info>

<Warning>
  This SDK is in **beta** and may change in the future.
  Please let us know if you encounter any issues or have suggestions for improvement.
</Warning>

## Prerequisites

* Install [Go](https://go.dev/doc/install)
* Get your Neynar API key from [neynar.com](https://neynar.com)

## Project Setup

**Initialize Project Directory**

<CodeGroup>
  ```bash Shell theme={"system"}
  mkdir get-started-with-neynar-go-sdk
  cd get-started-with-neynar-go-sdk
  go mod init getting_started
  ```
</CodeGroup>

**Add Neynar Go SDK as a dependency**

<CodeGroup>
  ```bash Shell theme={"system"}
  go get github.com/neynarxyz/go-sdk/generated/rust_sdk
  ```
</CodeGroup>

## Implementation: Look up a user by their verified address

Replace the contents of `main.go` with your Go code using the Neynar Go SDK.

<CodeGroup>
  ```go main.go theme={"system"}
  package getting_started

  import (
    "context"
    "fmt"

    openapiclient "github.com/neynarxyz/go-sdk/generated/neynar_sdk"
  )

  func main() {
    configuration := openapiclient.NewConfiguration()
    configuration.AddDefaultHeader("x-api-key", "NEYNAR_API_DOCS")
    apiClient := openapiclient.NewAPIClient(configuration)

    request := apiClient.UserAPI.
      FetchBulkUsersByEthOrSolAddress(context.Background()).
      Addresses("0xBFc7CAE0Fad9B346270Ae8fde24827D2D779eF07").
      AddressTypes([]openapiclient.BulkUserAddressType{openapiclient.AllowedBulkUserAddressTypeEnumValues[1]})

    resp, httpRes, err := request.Execute()
    if err != nil {
      fmt.Printf("Error: %v\n", err)
      return
    }
    defer httpRes.Body.Close()
    fmt.Printf("Users: %+v\n", resp)
  }
  ```
</CodeGroup>

## Running the project

<CodeGroup>
  ```bash Shell theme={"system"}
  go run main.go
  ```
</CodeGroup>

## Result

You should see a response similar to this (formatted for readability):

<CodeGroup>
  ```json Shell theme={"system"}
  Users: [{
      fid: 20603,
      username: "topocount.eth",
      display_name: "Topocount",
      // ...other fields...
  }]
  ```
</CodeGroup>

## Congratulations! You successfully set up the Neynar Go SDK and used it to look up a user by their address!
