Scope & Limits

Some areas of the product are intentionally limited, and the record keeps growing: coverage is extended house by house, and a source enters a reading only once its data is reliable enough.

Rather than presenting incomplete coverage as certainty, Artmetria shows what is available, what is partial, and what should be interpreted with caution.

Our goal is not to produce a vague ranking of artists or artworks, but to build one intelligence layer for art — Artmetria Intelligence — from which two products are drawn: Eye, for looking, and Market, for comparing and contextualising the art market.

Artmetria does not claim to cover the entire art market.

Coverage focuses on selected auction houses, categories and market segments where data can be monitored, normalised and interpreted with sufficient consistency.

Some sources may be watched without being fully indexed: they remain outside the active scoring perimeter until the data quality is considered reliable enough.

Coverage also has a field. The Reading Room reads fine art only — It reads paintings and drawings, and sculpture in a first, provisional coverage. It declines the rest rather than reading it badly, and says so before a photograph is sent. Market opens on fine art first, with paintings and drawings at its heart; the other categories the houses sell are shown as recorded, not read further. Each surface states its field where the limit applies.

When coverage is partial, Artmetria treats it as a methodological constraint, not as a hidden weakness.

The art market is uneven by nature.

Some regions have stronger public auction visibility. Others rely more heavily on galleries, private sales, fairs or informal networks.

Some categories produce frequent comparable records. Others are rare, episodic, highly specialised or dependent on expert attribution.

Artmetria’s coverage may therefore be stronger in some geographies, houses, periods or categories than in others.

This is not a failure of the method. It is a condition of responsible market interpretation.

Partial coverage means that Artmetria has some usable information, but not enough to treat a source, artist, segment or category as fully represented.

This may happen when:

• only some sales are available;
• lot-level information is incomplete;
• estimates or results are missing;
• historical depth is limited;
• source formats vary over time;
• image or provenance data is inconsistent;
• a category is too broad or too thin to compare reliably.

Partial coverage should not be read as absence of value. It means the available signal must be interpreted with caution.

The Artmetria Index and related scores are designed to organise market and object-level signals into a readable analytical framework.

They should not be understood as absolute judgements, price predictions, investment recommendations or guarantees of future performance.

A score may combine different layers of information, and this page says which. The Index value is composed from recorded market activity — price movement and transaction volume — and carries its coverage state and its confidence band. The reading of an object against ten explicit criteria — artist, period, execution, subject, technique, format and their like — is computed and kept with the value; since 20 September 2026 it no longer enters it, and it is not published as a figure. The value itself is withheld from the public site until the Index is finished.

Inside Market, a lot may carry a market indication: a range and a median drawn only from recorded, independent sales, with its sample, its dates and its limits beside it, and labelled as what it is — not an appraisal, not a certain value, not advice. Where the record is too thin, Market says "insufficient evidence" rather than producing a number.

Provenance, literature and condition are recorded where a catalogue publishes them, and they are part of the framework. They are not yet among the inputs a score is computed from, and this page will say so for as long as that remains true.

When data is incomplete, a reading should be read as limited, and it says so. Artmetria is designed to make this distinction visible over time.

Artmetria uses AI to help structure, explain and contextualise information.

Model-assisted outputs exist where a task genuinely calls for one — a work read in the Reading Room, an object read against explicit criteria beside the Index, images and texts represented so that neighbours can be found — and nowhere else: the Aesthetic Profile is built from your own choices, and Market's workflow calls no generative model. None of these outputs is an expert certificate, an authentication opinion, a legal opinion, tax advice or financial advice.

A model-assisted tool can be paused, and the pause fails closed: the surface says the tool is paused rather than serving a weaker answer. Whether the database and the model-assisted tools are reachable right now is measured, not written, on the service status page.

Where relevant, Artmetria aims to distinguish between descriptive information, interpretive commentary and market-related signals.

The AI layer is designed to support judgement, not replace it.

Artmetria does not provide financial advice, investment recommendations, buy/sell instructions or guarantees of value.

Any market signal, artist profile, comparable set or analytical note should be understood as educational and informational material.

Users should make independent decisions and, where appropriate, consult qualified professionals before making financial, legal, tax or acquisition-related decisions.

Auction data may vary depending on the availability, structure and consistency of public information.

Some records may be incomplete, delayed, revised or unavailable. Sale totals, estimates, lot information, images, provenance, exhibition history and literature references may differ from one source to another.

Artmetria’s role is to normalise and contextualise information where possible, while preserving caution when the underlying source material is limited.

Where a capability is restricted — to part of the art field, to a number of readings a month on the free plan, or to the sales a house has published — the restriction is stated on the surface itself, not in a footnote.

A figure the record cannot support is left absent and said to be; a reading that rests on too little says so. Neither is a defect: it is the method working.

Artmetria is built as a progressive analytical system.

Its value increases as coverage expands, data quality improves, scoring layers mature, and more interpretive signals become available.

What is open today is not presented as a finished authority, but as the first public version of a method.

If something is not covered, it should not be assumed to be unimportant.

If something is partially covered, it should not be treated as fully understood.

If something is actively covered, it should still be read within its category, source, region, date and confidence context.

Artmetria is designed to help users read market information more carefully, not to erase the complexity of the market itself.
