file	file	是	账单图片 (JPEG, PNG) 或 PDF 文档
return_image	boolean	否	在响应中包含 base64 编码的图像（默认：false）
return_ocr	boolean	否	在响应中包含原始 OCR 文本（默认：false）

错误处理

状态	代码	描述
400	BAD_REQUEST	参数或文件格式无效
401	UNAUTHORIZED	API 密钥无效或缺失
404	NOT_FOUND	端点无效
500	INTERNAL_SERVER_ERROR	处理失败

2. Base64 图像

POST https://api.iapp.co.th/ocr/v3/creditcard-statement/base64

请求头

名称	类型	是否必需	描述
apikey	string	是	您的 API 密钥

请求体

您可以将 base64 数据作为 JSON 或表单数据发送：

JSON 格式：

{
    "base64_string": "string", // Base64 编码的图像数据
    "return_image": false, // 可选
    "return_ocr": false // 可选
}

表单数据格式：

参数	类型	是否必需	描述
base64_string	string	是	Base64 编码的图像数据
return_image	boolean	否	在响应中包含 base64 编码的图像（默认：false）
return_ocr	boolean	否	在响应中包含原始 OCR 文本（默认：false）

响应格式

与文件上传端点相同
