Look up matches

Single keys

Given a key and a source, you can retrieve all keys resolving to the same entity in other sources. Useful for making ad-hoc queries for single data items.

from matchbox.client.dags import DAG

matches = DAG("companies").load_default().lookup_key(
    from_source="datahub_companies",
    to_sources=["companies_house"],
    key="8534735",
)

print(matches["datahub_companies"])
print(matches["companies_house"])

["8534735", "8534736"]
["EXP123", "EXP124"]

Extract whole lookup

You can download an entire lookup as a PyArrow table.

from matchbox.client.dags import DAG

lookup = DAG("companies").load_default().extract_lookup()
