Distinguish EstateSales.NET from EstateSales.org before recommending one for a listing or integration

Steps

1. Confirm these are two separate, similarly-named sites: EstateSales.NET (estatesales.net) and EstateSales.org (estatesales.org)
2. Note EstateSales.NET (previously operated as Vintage Software LLC) was acquired by Auction Technology Group plc (ATG) on Feb 7-8, 2023 for $40 million, per ATG's own press release at auctiontechnologygroup.com — putting it in the same corporate family as AuctionZip and Invaluable, which are also ATG brands
3. Note EstateSales.org remains a separately owned private company (EstateSales.org LLC, based in Austin, TX, with outside investment from DRD Capital) — it is not part of ATG — and positions itself as a shopper-facing marketplace with online auction/bidding features for items from estate sales
4. Confirm the only documented API integration found is Wavebid's EstateSales.NET connector, which uses an API key to link Wavebid to EstateSales.NET's servers — no equivalent public API confirmed for EstateSales.org
5. Verify current site scope, ownership, and any integration options directly with each company before assuming feature parity, since ATG's ownership of EstateSales.NET changes who to contact for business/API questions
