Sprift Insider API
The Insider tag of the published Sprift v1 contract — two operations exposing the market intelligence product that sits behind sprift.com/insider. GET /insider/{outcode} searches active properties by postcode outcode with an optional grouping parameter, and GET /insider/{outcode}/withdrawn returns withdrawn properties for the same outcode. This is the market-activity and agent-benchmarking surface — live stock, listings and withdrawals by area — rather than a single-property lookup.
