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

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.

## Prerequisites

- Install [Go](https://go.dev/doc/install)
- Get your Neynar API key from [neynar.com](/content/site-root.html)

## Project Setup

**Initialize Project Directory**

Shell

```
mkdir get-started-with-neynar-go-sdk
cd get-started-with-neynar-go-sdk
go mod init getting_started
```

**Add Neynar Go SDK as a dependency**

Shell

```
go get github.com/neynarxyz/go-sdk/generated/rust_sdk
```

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

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

main.go

```
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)
}
```

## Running the project

Shell

```
go run main.go
```

## Result

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

Shell

```
Users: [{\
    fid: 20603,\
    username: "topocount.eth",\
    display_name: "Topocount",\
    // ...other fields...\
}]
```

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