Spreedly
Spreedly 是一项服务，允许您安全地存储信用卡并使用它们与任意数量的支付网关和第三方 API 进行交易。它通过同时提供卡令牌化/保管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，然后根据您的业务需求将该卡传递到不同的端点。
此笔记本介绍如何将数据从Spreedly REST API加载到可以输入 LangChain 的格式中，以及向量化的示例用法。
注意：此笔记本假定已安装以下软件包：openai、chromadb和tiktoken。
import os
from langchain.indexes import VectorstoreIndexCreator
from langchain_community.document_loaders import SpreedlyLoader
API 参考：VectorstoreIndexCreator | SpreedlyLoader
Spreedly API 需要访问令牌，您可以在 Spreedly 管理控制台中找到它。
此文档加载器目前不支持分页，也不支持需要其他参数的更复杂对象的访问。它还需要一个resource选项，该选项定义您要加载的对象。

spreedly_loader = SpreedlyLoader(

)
# Create a vectorstore retriever from the loader
# see https://python.langchain.ac.cn/en/latest/modules/data_connection/getting_started.html for more details
index = VectorstoreIndexCreator().from_loaders([spreedly_loader])
spreedly_doc_retriever = index.vectorstore.as_retriever()
Using embedded DuckDB without persistence: data will be transient
# Test the retriever
spreedly_doc_retriever.invoke("CRC")
