Cenogram
Cenogram provides a comprehensive database of real estate transaction prices across Poland, offering over 8 million transaction records from 2003 onward. Users can filter by region, date, and property type, view maps, and download comparable transaction sets for appraisal reports. The platform targets appraisers, analysts, and real estate professionals seeking accurate market data.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Cenogram the way a machine reads it — 22 machine-readable artifacts across 1 API, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Cenogram scores 27.9/100 (thin), with a separate agent-readiness read of 40/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Cenogram
Each block below is one kind of artifact we hold for Cenogram. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 14
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Cenogram Demographics API
Demographic and economic indicators from GUS BDL (Central Statistical Office)
Cenogram Infrastructure API
Upcoming-infrastructure signals per municipality: public tenders, sewage-programme agglomerations, planned capital expenditure
Cenogram Locations API
District and location discovery
Cenogram Parcels API
Parcel-first lookup: resolve a cadastral identifier, read the parcel core, the deed history recorded against it, and per-parcel context layers (flood, zoning, permits, buildings...
Cenogram Spatial API
Geographic and polygon search
Cenogram Statistics API
Market statistics and price data
Cenogram Transactions API
Search and filter transactions
Cenogram Districts API
The Districts API from Cenogram — 2 operation(s) for districts.
Cenogram Infrastructure Signals API
The Infrastructure Signals API from Cenogram — 1 operation(s) for infrastructure signals.
Cenogram Permits API
The Permits API from Cenogram — 1 operation(s) for permits.
Cenogram Price Per M2 API
The Price Per M2 API from Cenogram — 1 operation(s) for price per m2.
Cenogram Stats API

Cenogram Valuations API
The Valuations API from Cenogram — 2 operation(s) for valuations.

Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Semantic Vocabularies 1
JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.
JSON-LD contexts and semantic vocabularies used across these APIs.
Cenogram Pl Context
JSON-LDSpectral Rules 1
Governance rulesets we run against this provider's specs — the automated checks behind parts of the score. Profiling them makes the quality bar explicit and re-runnable, not a matter of opinion.

SPECTRALJSON Schema 2
Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

PostApiV1ParcelsSpatialRequest
JSON SCHEMAPostApiV1TransactionsSpatialRequest
JSON SCHEMASecurity Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of Cenogram, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
