You have extractor and loader classes, I think the industry term at least in data warehousing is a
https://en.wikipedia.org/wiki/Extract,_transform,_load system. Enrichment sounds cool, too.
I like it, at least more than Zapier and similar pipelines. We have a couple of clients that use our API (geocoding[1]) to enrich their records inside an ETL. Be prepared that some APIs are rate-limited or quota-based, need API keys or other authentication and might return 'over-quota' error messages, never mind latency.
