# API Quick start

## Calling a public endpoint

To dive right in you can start by trying a call to one of Paradex's public endpoints:

# List available markets

GET

[https://api.testnet.paradex.trade/v1](https://api.testnet.paradex.trade/v1)    / markets

Get markets static data component

### Query parameters

market string Optional

Market Name - example: BTC-USD-PERP

### Request

GET [https://api.prod.paradex.trade/v1/markets](https://api.prod.paradex.trade/v1/markets)

```python
import requests
headers = {
  'Accept': 'application/json'
}

r = requests.get('https://api.prod.paradex.trade/v1/markets', headers = headers)

print(r.json())

```

```curl
curl -X GET https://api.prod.paradex.trade/v1/markets \
-H 'Accept: application/json'

```

```javascript
const headers = {
  'Accept':'application/json'
};

fetch('https://api.prod.paradex.trade/v1/markets',
{
  method: 'GET',

  headers: headers
})
.then(function(res) {
    return res.json();
}).then(function(body) {
    console.log(body);
});

```

```go
package main
import (
      "bytes"
      "net/http"
)

func main() {

    headers := map[string][]string{
        "Accept": []string{"application/json"},
    }

    data := bytes.NewBuffer([]byte{jsonReq})
    req, err := http.NewRequest("GET", "https://api.prod.paradex.trade/v1/markets", data)
    req.Header = headers

    client := &http.Client{}
    resp, err := client.Do(req)
    // ...
}

```

```ruby
require 'uri'
require 'net/http'

url = URI("https://api.prod.paradex.trade/v1/markets")

http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true

request = Net::HTTP::Get.new(url)

response = http.request(request)
puts response.read_body
```

```java
import com.mashape.unirest.http.HttpResponse;
import com.mashape.unirest.http.Unirest;

HttpResponse<String> response = Unirest.get("https://api.prod.paradex.trade/v1/markets")
  .asString();
```

```php
<?php
require_once('vendor/autoload.php');

$client = new \GuzzleHttp\Client();

$response = $client->request('GET', 'https://api.prod.paradex.trade/v1/markets');

echo $response->getBody();
```

```csharp
using RestSharp;

var client = new RestClient("https://api.prod.paradex.trade/v1/markets");
var request = new RestRequest(Method.GET);
IRestResponse response = client.Execute(request);
```

```swift
import Foundation

let request = NSMutableURLRequest(url: NSURL(string: "https://api.prod.paradex.trade/v1/markets")! as URL,
                                        cachePolicy: .useProtocolCachePolicy,
                                    timeoutInterval: 10.0)
request.httpMethod = "GET"

let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
  if (error != nil) {
    print(error as Any)
  } else {
    let httpResponse = response as? HTTPURLResponse
    print(httpResponse)
  }
})

dataTask.resume()
```

## Interacting with private endpoint

To interact with private Paradex endpoints you need to onboard and generate a [JSON Web Token (JWT)](https://jwt.io/introduction) before making API requests. JWTs are a secure way to transmit information between parties. Please refer to the **Authentication** chapter and [onboarding and authentication code samples](https://github.com/tradeparadex/code-samples).
