### Generate X-API-SIGN Signature for FixedFloat API Requests

Source: https://ff.io/api/index

Demonstrates how to generate the X-API-SIGN header required for authenticated FixedFloat API requests. This involves using HMAC SHA256 with your API Secret and the JSON data string. The examples cover command-line (openssl), Python, and PHP implementations.

```bash
#!/bin/bash
echo -n 'DATA_JSON' | openssl dgst -sha256 -hmac "YOUR_API_SECRET"

```

```python
import hmac
import json
import hashlib
import requests

def sign(data):
  return hmac.new(
    key=YOUR_API_SECRET.encode(),
    msg=data.encode(),
    digestmod=hashlib.sha256
  ).hexdigest()

def request(method, params={}):
  url = 'https://ff.io/api/v2/' + method
  data = json.dumps(params)
  headers = {
    'X-API-KEY':  YOUR_API_KEY,
    'X-API-SIGN': sign(data)
  }
  r = requests.post(url, data=data, headers=headers)
  return r.json()

request(METHOD, DATA)

```

```php
<?php
  function sign($data) {
    return hash_hmac('sha256', $data, YOUR_API_SECRET);
  }
  
  function request($method, $data) {
    $url = 'https://ff.io/api/v2/'.$method;
    
    $req = json_encode($data);
    
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(

      'X-API-KEY: '  . YOUR_API_KEY,
      'X-API-SIGN: ' . sign($req)
    ));
    $response = curl_exec($ch);
    curl_close($ch);
    
    $result = json_decode($response, true);
    if ($result['code'] == 0) {
