title: Cenogram Statistics API
version: 1.0.0
description: 'Property and parcel intelligence for Poland. 8M+ verified transactions from the official RCN registry (Rejestr Cen Nieruchomości) — prices from notarial deeds, not asking/listing prices, from 2003 to present, nationwide. On top of prices: the picture we hold of a parcel — cadastral core, the deed history recorded against it, and context layers (flood hazard, general-plan zoning, building permits, structures, heritage, landslide hazard, subsurface constraints from mining terrains and groundwater reservoirs, surroundings, transit access, road access, agricultural use), plus municipality-level demographics and infrastructure signals, and a comparable-based valuation estimate. Context layers are sourced from official public registers. Transaction coverage is nationwide; the cadastral parcel corpus is near-complete but not the whole register and not live — every parcel collection carries a `corpus_coverage` block measuring what we hold for the counties it addresses. Access is metered in tokens: a new account starts with a token allowance and a trial, after which a free account keeps calling on a recurring free allowance, and paid plans raise it. Current allowances, trial length and prices live at https://cenogram.pl/api and are deliberately not repeated here, because a figure frozen into this description goes stale on its own. A 402 response carries the current balance and, on a free account, the date the next tokens arrive. Every operation states its price both in prose and machine-readably, in the `x-cenogram-token-cost` extension field, generated from the one pricing table. Tokens and credits are the same unit under two names: the response headers (`X-Credits-Cost`, `X-Credits-Balance`, `X-Credits-Refunded`) and some older endpoint descriptions say credits. Working with an AI assistant? Give it https://cenogram.pl/api/llms.txt — this whole surface as one plain-text file, costs, refund rules and response conventions included.'
