Please stand by @Joey as I search the knowledge base. I normally take about 20 seconds or so. :wave:

To use a loaded index outside of its scope in another API, you would typically serialize the index and load it in the context of the other API. However, the specific method would depend on the APIs you're working with.

In the context of LlamaIndex, you can persist and load data using the StorageContext. Here's an example of how you can load data:

Plain Text
from llama_index import (
    load_index_from_storage,
    load_indices_from_storage,
    load_graph_from_storage,
)

storage_context = StorageContext.from_defaults(
    docstore=SimpleDocumentStore.from_persist_dir(persist_dir="<persist_dir>"),
    vector_store=SimpleVectorStore.from_persist_dir(
        persist_dir="<persist_dir>"
    ),
    index_store=SimpleIndexStore.from_persist_dir(persist_dir="<persist_dir>"),
)

# load a single index
# need to specify index_id if multiple indexes are persisted to the same directory
index = load_index_from_storage(storage_context, index_id="<index_id>")

# don't need to specify index_id if there's only one index in storage context
index = load_index_from_storage(storage_context)

# load multiple indices
indices = load_indices_from_storage(storage_context)  # loads all indices
indices = load_indices_from_storage(
    storage_context, index_ids=[index_id1, ...]
)  # loads specific indices

# load composable graph
graph = load_graph_from_storage(
    storage_context, root_id="<root_id>"
)  # loads graph with the specified root_id

(Source: LlamaIndex Documentation ())

Please replace <persist_dir> and <index_id> with your actual directory and index id.
Once you have loaded the index, you can use it for querying or any other operations as per your requirements. If you want to use this in another API, you would typically expose the functionality through an API endpoint.

Please note that the specifics of how you would use this in another API would depend on the framework and language you're using for your API.
