Spreedly

Spreedly 是一个服务，允许您安全地存储信用卡并将其用于与任意数量的支付网关和第三方API进行交易。它通过同时提供卡片令牌化/保险库服务以及网关和接收器集成服务来实现此目的。由Spreedly令牌化的支付方式存储在Spreedly中，允许您独立存储卡片，然后根据业务需求将该卡片传递给不同的终端点。

本笔记本介绍了如何从Spreedly REST API中加载数据，并将其转换为可以被LangChain接受的格式，以及向量化的示例用法。

注意：本笔记本假设已安装以下软件包：openai、chromadb和tiktoken。

import os

from langchain.document_loaders import SpreedlyLoader
from langchain.indexes import VectorstoreIndexCreator

Spreedly API需要一个访问令牌，可以在Spreedly管理控制台中找到。

此文档加载程序目前不支持分页，也不支持访问需要额外参数的更复杂的对象。它还需要一个resource选项，用于定义要加载的对象。

以下资源可用：

spreedly_loader = SpreedlyLoader(
    os.environ["SPREEDLY_ACCESS_TOKEN"], "gateways_options"
)

# 从加载程序创建一个向量存储检索器
# 有关更多详细信息，请参见https://python.langchain.com/en/latest/modules/data_connection/getting_started.html

index = VectorstoreIndexCreator().from_loaders([spreedly_loader])
spreedly_doc_retriever = index.vectorstore.as_retriever()

    Using embedded DuckDB without persistence: data will be transient

# 测试检索器
spreedly_doc_retriever.get_relevant_documents("CRC")
