wss://ws.newlistings.pro/v1/feed
The feed channel is the free key's compact stream of listings and delistings. Standard FREE keys add a 3-second publish delay and allow up to 2 IP addresses. See Keys for current plan settings. This path is stream-only and has no historical GET.
Listings from both source groups are included; tier identifies the group. Delistings remain primary-only.
