106 tools

• entity_search_capabilities

  Governed entity families, criteria, coverage and query limits. Call before building searches. Free.

• lookup_entities

  Find public records by title/address text, postcode or public UUID. Exact and lexical lookup uses no model or embeddings; supports token prefixes and bounded typo tolerance in accepted search publications. Returns separate families with UUID detail links and explicit searched…

• ask_question

  Use the SAME Ask router as the portal. Route a place/kind into the published taxonomy, a dated figure to the governed semantic query, or exact company/property/title references to a bounded corporate network/path. This tool proposes execution; it does not execute paid work…

• search_entities

  Bounded public search using the versioned SearchQuery. Criteria are validated by the server; sorting and pagination use the same eligibility as the map. All Entities returns separate groups. No graph inference or unknown evidence changes eligibility. QUERY SHAPE — `query`…

• search_summary

  Counts and statistics over EXACTLY what `search_entities` would match: how many records, grouped by a field, with min, median, mean and max of up to three numeric fields. Use it for "how many", "what share", "median floor area" and "price by type" questions instead of paging…

• market_profile

  One market profile: an area × residential bedroom cohort with every published measure — asking sale price and rent, completed sale price, gross yield on asking, live stock, new listings, price reductions, turnover and registry sale volume — each with its `basis` sentence, unit…

• entity_relationships

  Recorded relationship evidence from the derived graph. Use canonical ids from search. Cite path provenance and publication dates. Bounded and eventually consistent; missing links do not establish absence, ownership or off-market status. No private ownership payloads are…

• actor_network

  Investigate recorded corporate ownership, title and agency relationships. Requires the customer's account; never use an anonymous preview key. Depth 1–3, at most 100 nodes; clipped networks explicitly say truncated. Cite publication IDs and provenance on each hop. Missing links…

• actor_path

  Find a recorded path between two corporate-network records within three hops. Requires the customer's account. A clipped search returns incomplete, never a claim that no relationship exists. Return the ordered hops with their source/publication evidence. Costs 15 credits (15p).

• address_autocomplete

  Address autocomplete. Returns ranked candidates for a partial address or postcode. Use `address_resolve` to turn a candidate into a canonical UPRN. This is the free entry point: resolve, lookup and postcode listing are priced because they return OS AddressBase…

• address_resolve

  Resolve free-text address to canonical record (UPRN for UK). Costs 2 credits (2p); free on marketcode.ai.

• address_by_uprn

  Look up an address by UPRN (UK only). Costs 1 credit (1p); free on marketcode.ai. Keyed on a UPRN, not an address: call `address_autocomplete` (free) to narrow, then `address_resolve` to get one.

• address_by_postcode

  Return all addresses at a UK postcode. Costs 2 credits (2p); free on marketcode.ai.

• property_lookup

  Full property record for a UPRN, grouped into tiers: identity, property, energy, building, land, risk, designations, infrastructure, ownership, provenance. Up to ~300 fields — null fields are omitted, so a typical urban flat returns fewer than a rural site with…

• property_reconcile

  Cross-source property facts with provenance and unresolved attributes. Review floor area, bedrooms and tenure with the user before a valuation. `ml_primary` and `imputed` are predictions, not measurements; a warehouse value is not automatically declared…

• market_facts

  Price, price per sqm and turnover rate for ONE geography × asset class × bedroom band × period, from the pre-cubed area_facts table. Metrics: sales_price, price_psm, turnover_rate are populated today. rental_value, gross_yield and days_on_market are NOT — the…

• market_ranking

  Rank areas AGAINST EACH OTHER on a market metric — one row per area, AGGREGATED over a trailing window of whole months. This is the comparison tool. `market_facts` answers for one geography; calling it in a loop to build a league table is slower, costs more and…

• market_volume_series

  Monthly transaction VOLUME for a postcode district, postcode area or county — every registered sale, 1995 to present, oldest month first. Use this, not `market_facts`, for "how many sales" questions. `market_facts` reads the area_facts cube, whose count is a…

• market_index_series

  The published house-price INDEX for one postcode district or local authority: the level per month (base period = 100), the forecast tail flagged, and provenance saying how the index was built. Use this for "how has W14 moved since 2015", "what is the trend in…

• market_yields

  Gross rental yield for an area and bedroom band on two bases, by month, with n: `gross_yield_asking` (12 × the month's median asking rent ÷ the median asking price of sale listings in the same area, band and month — different properties) and `gross_yield_avm_median`…

• market_forecast

  The published house-price index forecast for a postcode district or local authority: the last SETTLED index point as the anchor, then up to seven forecast periods with `lo`/`hi` bands, plus the method and publication grain behind them. Seven is the horizon the index…

• supply_demand

  Supply and demand for an area in one call: live stock today (count, median days on market, new-home count) and the monthly flow — listings added and reduced, reduction share, new-home share, agent concentration, asking-to-sold on the registry-matched subset and days…

• time_adjustment

  The factor that carries a price paid in a past month to the latest SETTLED month of the published repeat-sales house-price index: the postcode district's own series, else its local authority's, else the national series; forecast months are never used. Returns…

• commercial_index_series

  Repeat-sales CAPITAL index for UK commercial property, quarterly, 1995Q1 = 100. Three families exist and nothing else: national ALL; national x sector for the sectors that passed the level gate (OFFICE, RETAIL, HOTEL, HOLIDAY_LET); and local authority x ALL for…

• commercial_rent_index_series

  Commercial RENT index from the VOA rating lists — FOUR points, one per list (2010 / 2017 / 2023 / 2026), each dated at that list's antecedent valuation date (2008-04-01, 2015-04-01, 2021-04-01, 2024-04-01), with the 2010 list = 100. READ `basis` AND REPEAT IT…

• market_volume_ranking

  Rank postcode districts by transaction volume or median price over a trailing window — "the busiest districts in Greater London last year", "the priciest districts in SW". Restrict the candidate set with county ("GREATER LONDON") or area ("SW"); omit both to…

• transactions_by_uprn

  All HMLR Price Paid records joined to this UPRN, newest first. England & Wales only. Free. Keyed on a UPRN, not an address: call `address_autocomplete` (free) to narrow, then `address_resolve` to get one.

• property_summary

  One-call summary of a property: what it is, what building it belongs to, and the headline attributes. Once you have the UPRN this is the first call to make for a specific property — it usually answers the question on its own, and `property_report` composes the rest…

• property_history

  Sold-price history for a property, with per-sale detail. Use `transactions_by_uprn` instead if you only need the raw HMLR rows. UK only. Free. Keyed on a UPRN, not an address: call `address_autocomplete` (free) to narrow, then `address_resolve` to get one.

• property_comps

  Comparable sales in the same building or block. Preserve original price, sale date, UPRN and `attrs_source`. Backfilled/modelled floor areas are estimates: their derived price per square metre is not directly observed. An EPC room count is not automatically a bedroom…

• property_flood_risk

  Environment Agency surface-water flood risk for a property. UK only. Free. Keyed on a UPRN, not an address: call `address_autocomplete` (free) to narrow, then `address_resolve` to get one.

• valuation_estimate

  Automated value estimate for a property: a point value plus a range. Returns 404 when we hold no valuation for the UPRN — most often because the unit has no floor area on record, which the model requires. UK only. Free. Keyed on a UPRN, not an address: call…

• valuation_full

  Full valuation block for a property: the value and its range, a monthly back-series (the value scaled by the local £/m² index, so it terminates at the headline figure by construction), a rental estimate where the district benchmark supports one, and a `trust_score`…

• property_lease

  Registered leases linked to this UPRN, with the selected longest-expiry record and up to ten alternatives, exact register property descriptions, title/record identifiers, source/link limitations and computed remaining term. UPRN linkage does not verify the legal…

• property_lease_batch

  `property_lease` for up to 100 properties in one call, per-item outcomes (ok | no_lease | not_found | error) in input order. Charged per property answered — the sum of the single calls, never more. UK only. Costs 5 credits (5p). Keyed on a UPRN, not an address: call…

• property_risk_report

  What this property is in, and whether we actually checked: every designation and hazard flag THREE-VALUED with its source — flood (zone, historic flooding, defences, rivers-and-sea band, surface water), coal (high-risk area, past mining, surface hazard distance)…

• property_risk_report_batch

  `property_risk_report` for up to 100 properties in one call, per-item outcomes (ok | not_found | error) in input order. Charged per property answered — the sum, never more. UK only. Costs 5 credits (5p). Keyed on a UPRN, not an address: call `address_autocomplete`…

• comps_adjustments

  The evidence behind a valuation, itemised: same-building comparable sales for the property, each with its registered price and date, its time adjustment on the published repeat-sales index (the district's own series, else the local authority's, else national) to the…

• valuation_comparables

  Comparable completed sales for a valuation, beyond the property's own building: Land Registry sales of the nearest units (within 1 km, the 60 months before `as_of`), widening from 250 m and 12 months until at least 6 qualify. A sale qualifies when it is the same…

• valuation_rent_comparables

  Comparable lets for a market rent, and the rent they indicate. ASKING rents from portal adverts: no achieved rents exist, so say "asking" when you quote them. Reads the rent adverts of the nearest units (within 1 km, last seen in the 24 months before `as_of`)…
