A norm, at a date, signed

What this operation sells, what it costs, and what it will not do.

A signed assay is €2,400: one capability class across one declared population at one declared date, delivered with the method so the result can be recomputed against us.

The question an assay answers is not does this site have an AI policy. It is what was the state of the art, across a defined population, on a given date — the form the question takes when a dispute turns on whether a machine-readable reservation of rights existed at the time of use, or when a party selling a capability needs to show the gap it closes is real.

What is on offer

Engagement	What it is	Price
Assay	One capability class, one declared population, one declared date. The rate with its confidence interval, the evidence count behind it, the signed chain records it was computed from, and the method in enough detail to reproduce the figure independently.	€2,400
Extended assay	Up to five classes, or one class across several populations or several dates. Cross-sections are reported separately and never pooled — pooling populations moved our own published rates once, and that correction is why they are kept apart.	€6,000
Measurement review	A written review of somebody else's published figure against this method: what it supports, what it does not, and where ours differs and why. Six published llms.txt adoption figures span 8.3×, so a party citing one is choosing between numbers that disagree by an order of magnitude.	€1,800
Standing monitor	The classes of a completed engagement, re-measured and signed each quarter, so a norm can be shown to have moved or held. A single date cannot answer that.	€1,200/ quarter

What you are told before you pay

These are the limits of the instrument, and they are stated here rather than in a footnote because an outside reviewer tested our published figures against them and all four of their corrections held.

A rate is a rate for the declared target set. It is a sample, not a census.
Absence of a machine-readable signal is an upper bound on absence of the capability, not proof of it. Where the instrument cannot tell the two apart, the record says unknown rather than guessing.
Measurement is from a single vantage. A series that mixed vantages would mix where with when.
History before 2026-09-20 is reconstructed from a public web archive, not observed contemporaneously.

What is not for sale

Findings about an individual named third party's own site or conduct, at any price. Everything we observe is published and delivered in aggregate. A measurement that a third party has published itself is a public claim rather than an observation of ours, and may be cited and examined by name, as any review cites its sources.
A figure to order. The number is whatever the signed record says for the date asked about. If it does not support the claim a buyer wants, that is the finding, and we say so.
A measurement that cannot be recomputed. If the method cannot be published with the result, the result is not for sale.

How to start

Write to info@geosensor.tech with the class, the population and the date you need. You will get back either a scope and a price, or the reason the question cannot be answered to that standard — which is the more useful answer when it is the true one.

⚠️ An engagement is deliberately not machine-purchasable. It needs a scope agreed in writing, and wiring a payment route to it would sell something nobody had defined.

Self-serve, no conversation needed

The measurements themselves are free and need no credential: the adoption series, the absence rates, the endpoint-health decomposition, and the written findings. For software that wants the aggregate tables rather than a report, the paid export is $0.02 or €0.02 per call over x402, and a subscription is €19 or €99 a month — both live, both working, and neither of them the thing this operation sells.
