根据银行简称查询银行详细名称。银行数据库会随时更新

请求地址：https://payjs.cn/api/bank

请求参数：

请求返回：

未查询到银行名称则返回 "not found"

该接口请求频率为50次/分

演示代码：

// 引入 payjs.class.php
// 项目地址：https://github.com/payjs-cn/phpsdk

include("payjs.class.php");

$mchid = '123456';
$key = 'xxxxxx';

$data = [
    "mchid" => $mchid,
    "bank" => 'XXX',
];

$payjs = new Payjs($mchid, $key);
$result = $payjs->bank($data);

print_r($result);
