Street.co.uk (Street Systems Limited, Manchester, England) is a UK estate agency CRM and property management platform for residential sales, lettings, property management and client accounting. In the United Kingdom there is no MLS and no RESO — residential listing distribution runs from agency CRM software out to the Rightmove and Zoopla portals — which places Street.co.uk at the agency system-of-record layer of the value chain, upstream of the portal duopoly and alongside Reapit, Alto and Apex27. Its API posture is unusually open for this sector: three OpenAPI 3.1 contracts (Street Open API, Property Feed, Spectre) are published unauthenticated on a public Scalar developer portal at developers.street.co.uk and can be downloaded as JSON or YAML by anyone. Access to the data behind them is not open — production bearer tokens are generated inside a paying agency's Street account under Settings > Account Administration > Applications, and a non-customer developer must email apis@street.co.uk to be issued a sandbox token on the staging environment. Nothing RESO, no OData $metadata, and no open government data is published by Street.co.uk itself; the open UK property data layer sits with HM Land Registry and Ordnance Survey, not with the CRM vendors.
