API | FixedFloat

Introducción

La API de FixedFloat le permite automatizar la recepción de información sobre los tipos de cambio de las divisas, las órdenes creadas, presentadas en el servicio de FixedFloat, crear órdenes y gestionarlas usándola.

Para utilizar la API de FixedFloat, debe obtener una API key y un API secret.

Obtener la API key

Para obtener una API Key y un API Secret, siga estos pasos:

Inicie sesión o Regístrese en FixedFloat
Ir a la sección API management
Haga clic en el botón "Generar" y siga las instrucciones en la ventana que aparece
Copie la API Key y el API Secret y guárdelos en un lugar seguro. Use estos parámetros para solicitudes a la API FixedFloat

Solicitud y ejemplo

Los datos enviados deben estar en formato JSON con codificación UTF-8.

Para solicitudes de API exitosas, todas las solicitudes deben contener algunos encabezados obligatorios:

El encabezado Content-Type debe ser application/json; charset=UTF-8
El encabezado X-API-KEY debe contener su API Key (YOUR_API_KEY)
The X-API-SIGN header must contain the signature GENERATED_SIGN. Para obtener la firma, debe usar su API Secret (YOUR_API_SECRET) como clave de operación HMAC SHA256 y la cadena de datos json como valor.

X-API-SIGN generation

Curl Python PHP


[linux]$ echo -n 'DATA_JSON' | openssl dgst -sha256 -hmac "YOUR_API_SECRET"
(stdin)= GENERATED_SIGN


cURL -X POST \
  -H "Accept: application/json" \
  -H "X-API-KEY: YOUR_API_KEY" \
  -H "X-API-SIGN: GENERATED_SIGN" \
  -H "Content-Type: application/json; charset=UTF-8" \
  -d 'DATA_JSON'
  "https://ff.io/api/v2/METHOD" -L


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
  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(
      'Content-Type:application/json',
      '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) {
      return $result['data'];
    } else {
      throw new Exception($result['msg'], $result['code']);
    }
  }
  
  request(METHOD, DATA);
?>

Solicitar límites

El límite de solicitud por minuto es de 250 unidades.

La solicitud /api/v2/create cuesta 50 unidades, todas las demás solicitudes cuestan 1 unidad.

Si se excede el límite, su token se bloqueará temporalmente. Con cada superación posterior del límite después del desbloqueo, el tiempo de bloqueo aumentará

Tipo de cambio

POSThttps://ff.io/api/v2/price

Obtener el tipo de cambio de un par de divisas en la dirección y el tipo de cambio seleccionados.

ATTENTION! Para obtener las tasas de cambio de todas las monedas disponibles, debe usar el archivo de tasa de exportación disponible en el enlace https://ff.io/rates.xml

Para este método, así como para el método /api/v2/create, es posible aumentar las ganancias acumuladas en el programa de afiliados utilizando el parámetro afftax.

El tipo de cambio final al pasar los parámetros afftax y refcode depende de si su código de programa de afiliados ha sido aprobado para obtener ingresos por pedidos generados por la API y el porcentaje base (AFFBASE) establecido para su código, y se calculará de acuerdo con la fórmula:


total = FF - AFFB + afftax, si afftax < FF - AFFB
total = afftax x 2        , si FF - AFFB < afftax < FF
total = FF + afftax       , si afftax > FF

donde FF es el porcentaje base del servicio para el tipo de cambio seleccionado (1% para tasa fija y 0,5% para tasa flotante);
AFFB es el porcentaje base del beneficio del servicio establecido para su código de programa de afiliados, para el tipo de cambio seleccionado (AFFBASE para una tasa fija y AFFBASE÷2 para una tasa flotante)

Para mayor claridad, le sugerimos que se familiarice con la siguiente tabla con AFFBASE=0.4, where FFP = FF - AFFB:

FIXED RATE			FLOAT RATE
Total	FFP	afftax	Total	FFP	afftax
1.0	0.6	0.4	0.5	0.3	0.2
1.1	0.6	0.5	0.55	0.3	0.25
1.2	0.6	0.6	0.6	0.3	0.3
1.4	0.7	0.7	0.7	0.35	0.35
1.6	0.8	0.8	0.8	0.4	0.4
1.8	0.9	0.9	0.9	0.45	0.45
2.0	1.0	1.0	1.0	0.5	0.5
2.1	1.0	1.1	1.05	0.5	0.55
2.2	1.0	1.2	1.1	0.5	0.6

Si su código de afiliado no tenía establecido un porcentaje de ganancias de API base, la tasa de cambio final se calculará como:


FF + afftax

donde FF es el porcentaje base del servicio para el tipo de cambio seleccionado (1% para tasa fija y 0,5% para tasa flotante).

Las ganancias se acreditarán en su cuenta si el código del programa de afiliados se pasó en el parámetro refcode y este código pertenece a su cuenta. De lo contrario, se ignorarán los parámetros afftax y refcode.

Parámetros

type	true	string	Order type
fromCcy	true	string	Code of the currency the client wants to send
toCcy	true	string	Code of the currency the client wants to receive
