Site appraisal
GET /v1/site/appraisalEverything known about one site, assembled and judged.
Site build cost
GET /v1/site/build-costBuild cost for a scheme: the sector's cost index with its 1- and 5-year movement, the regional location factor, the editorial on-cost percentages and, given a GIA and a £/m² rate, an estimate — the rate rebased through the index, localised, multiplied out, totals at low / mid / high on-costs. The £/m² benchmark leg says `not_available` until a tender benchmark is loaded; nothing here is a modelled number.
Site cost index
GET /v1/site/cost-indexConstruction cost index series — tender prices, output prices, the construction deflator and labour — by sector and frequency, each series with its base period and method. The cost side of a development appraisal, from the same table the site appraisal's build cost will read.
Sourcing commercial
POST /v1/sourcing/commercialRated commercial stock in a local authority, filtered by sector and rateable value: each row with its income-basis value, freeholder where a title links, and auction history. No £/m² is published — the VOA's measured area is not loaded, and the twin's unit-level area is not comparable with a hereditament-level rateable value.
Sourcing land assembly
GET /v1/sourcing/land-assemblyThe parcels adjacent to one parcel, who owns each, and what the combined site would be: total area, distinct owners, how many neighbours share the subject's proprietor, and the constraints across the whole assembly.
Sourcing live listings
POST /v1/sourcing/live-listingsWhat is on the market right now in these postcode districts, enriched against the twin: asking against our valuation, £/m², yield on both bases, lease years, EPC and its retrofit gap, the designation flags, days listed and the agent, with a signals line per row.
Sourcing offmarket owners
POST /v1/sourcing/offmarket-ownersWho owns the stock in an area — optionally only the stock a strategy points at — ranked by holding size, tenure and equity, with company status and the signals behind the rank.
Sourcing owners
POST /v1/sourcing/ownersResolve registered owners for parcels returned by a sourcing search.
Sourcing parcel
GET /v1/sourcing/parcelOne land parcel in full: INSPIRE id, title number and OS id, area and land use, the registered proprietor where a title links, the units standing on it, plot utilisation, and every constraint flag three-valued.
Sourcing search
POST /v1/sourcing/searchFind land parcels or residential units matching investment criteria.
Sourcing strategies
GET /v1/sourcing/strategiesThe sourcing strategy presets as data: each one's filters (every key overridable, with its default and unit), its ranking components with weights and scales, the columns it reads, the data gaps that limit it and its version. Pass `area` as a LAD GSS code for `data_ready` per strategy.
