Spreedly는 신용카드를 안전하게 저장하고 다양한 결제 게이트웨이 및 서드파티 API에 대해 거래할 수 있게 해주는 서비스입니다. 카드 토큰화/금고 서비스와 게이트웨이 및 수신자 통합 서비스를 동시에 제공함으로써 이를 달성합니다. Spreedly에서 토큰화된 결제 수단은 Spreedly에 저장되므로, 카드를 독립적으로 저장한 다음 비즈니스 요구 사항에 따라 해당 카드를 다른 엔드포인트로 전달할 수 있습니다.
이 노트북은 Spreedly REST API로부터 데이터를 로드하여 LangChain에 수집할 수 있는 형식으로 변환하는 방법과 벡터화를 위한 사용 예제를 다룹니다. 참고: 이 노트북은 다음 패키지가 설치되어 있다고 가정합니다: openai, chromadb, tiktoken. 
import os

from langchain.indexes import VectorstoreIndexCreator
from langchain_community.document_loaders import SpreedlyLoader
Spreedly API는 Spreedly 관리 콘솔 내에서 찾을 수 있는 액세스 토큰이 필요합니다. 이 문서 로더는 현재 페이지네이션을 지원하지 않으며, 추가 매개변수가 필요한 더 복잡한 객체에 대한 액세스도 지원하지 않습니다. 또한 로드하려는 객체를 정의하는 resource 옵션이 필요합니다. 다음 리소스를 사용할 수 있습니다: 
spreedly_loader = SpreedlyLoader(
    os.environ["SPREEDLY_ACCESS_TOKEN"], "gateways_options"
)

# Create a vectorstore retriever from the loader
# see https://python.langchain.com/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")
