Let’s load the Bookend AI Embeddings class. 
from langchain_community.embeddings import BookendEmbeddings

embeddings = BookendEmbeddings(
    domain="your_domain",
    api_token="your_api_token",
    model_id="your_embeddings_model_id",
)

text = "This is a test document."

query_result = embeddings.embed_query(text)

doc_result = embeddings.embed_documents([text])
