Both Cloudflare account ID and API token are required. Find how to obtain them from this document.

import getpass

my_account_id = getpass.getpass("Enter your Cloudflare account ID:\n\n")
my_api_token = getpass.getpass("Enter your Cloudflare API token:\n\n")

Example​

from langchain_community.embeddings.cloudflare_workersai import (
    CloudflareWorkersAIEmbeddings,
)
embeddings = CloudflareWorkersAIEmbeddings(
    account_id=my_account_id,
    api_token=my_api_token,
    model_name="@cf/baai/bge-small-en-v1.5",
)
# single string embeddings
query_result = embeddings.embed_query("test")
len(query_result), query_result[:3]
(384, [-0.033627357333898544, 0.03982774540781975, 0.03559349477291107])
# string embeddings in batches
batch_query_result = embeddings.embed_documents(["test1", "test2", "test3"])
len(batch_query_result), len(batch_query_result[0])
(3, 384)
