Introdução

A API FixedFloat permite automatizar o recebimento de informações sobre as taxas de câmbio das moedas, pedidos criados, apresentados no serviço FixedFloat, criar pedidos e gerenciá-los usando-o.

Para usar a API FixedFloat, você precisa obter uma API key e um API secret.

Obtendo a API key

Para obter uma API Key e API Secret, siga estas etapas:

  1. Entre ou Registre-se no FixedFloat
  2. Vá para a seção API management
  3. Clique no botão "Gerar" e siga as instruções na janela que aparece
  4. Copie a API Key e o API Secret e guarde-os em um local seguro. Use esses parâmetros para solicitações à API FixedFloat

Pedido e exemplo

Os dados enviados devem estar no formato JSON com codificação UTF-8.

Para solicitações de API bem-sucedidas, todas as solicitações devem conter alguns cabeçalhos obrigatórios:

  • O cabeçalho Content-Type deve ser application/json; charset=UTF-8
  • O cabeçalho X-API-KEY deve conter sua API Key recebida (YOUR_API_KEY)
  • O cabeçalho X-API-SIGN deve conter a assinatura GENERATED_SIGN. Para obter a assinatura, você deve usar seu API Secret (YOUR_API_SECRET) como a chave de operação HMAC SHA256 e a string de dados json como o valor.

Solicitar limites

O limite de solicitação por minuto é de 250 unidades.

A solicitação /api/v2/create custa 50 unidades, todas as outras solicitações custam 1 unidade.

Se o limite for excedido, seu token será temporariamente bloqueado. Com cada superação subsequente do limite após o desbloqueio, o tempo de bloqueio aumentará

Bibliotecas Oficiais

Você pode usar bibliotecas prontas para usar a API FixedFloat:

Moedas disponíveis

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

Obtendo uma lista de moedas suportadas pelo serviço FixedFloat, bem como dados em seu display e informações sobre a disponibilidade para recebimento e envio.

Parâmetros

Não há necessidade de passar parâmetros para esta solicitação.

X-API-SIGN é gerado chamando a função HMAC SHA256 de uma string vazia se nenhum parâmetro for passado ou de um objeto JSON vazio.

Example request
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" \
  "https://fixedfloat.com/api/v2/ccies" -L
<?php
  require_once('fixedfloat.php');
  
  $ff = new FixedFloatApi(YOUR_API_KEY, YOUR_API_SECRET);
  
  return $ff->ccies();
?>

Taxa de câmbio

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

Obtendo a taxa de câmbio de um par de moedas na direção selecionada e tipo de taxa.

ATTENTION! Para obter as taxas de câmbio de todas as moedas disponíveis, você deve usar o arquivo de taxa de exportação disponível no link https://ff.io/rates.xml

Para este método, assim como para o método /api/v2/create, é possível aumentar os ganhos acumulados no programa de afiliados usando o parâmetro afftax.

A taxa de câmbio final ao passar os parâmetros afftax e refcode depende se o código do seu programa de afiliados foi aprovado para ganhar pedidos gerados pela API e a porcentagem base (AFFBASE) definida para o seu código e será calculada de acordo com a fórmula:

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

onde FF é a porcentagem base do serviço para o tipo de câmbio selecionado (1% para taxa fixa e 0,5% para taxa flutuante);
AFFB a porcentagem base do lucro do serviço definido para o código do seu programa de afiliados, para o tipo de taxa de câmbio selecionado (AFFBASE para uma taxa fixa e AFFBASE÷2 para uma taxa flutuante)

Para maior clareza, sugerimos que você se familiarize com a tabela abaixo com 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

Se o seu código de afiliado não tiver uma porcentagem básica de ganhos da API definida, a taxa de câmbio final será calculada como:

FF + afftax

onde FF é a porcentagem base do serviço para o tipo de câmbio selecionado (1% para taxa fixa e 0,5% para taxa flutuante).

Os ganhos serão creditados em sua conta se o código do programa de afiliados for passado no parâmetro refcode e esse código pertencer à sua conta. Caso contrário, os parâmetros afftax e refcode serão ignorados.
