Rights, coverage and refresh decide 42% of the score and none of them are visible in the data.

    How a lab would read it

    02 / DEMAND

    What labs are hunting.

    The web kept the finished output and threw away the process. The process is what's scarce.

    CategoryDemand90-day

    Seeded from public licensing activity through mid-2026. Buyer briefs replace these numbers as they land.

    03 / RUBRIC

    What the assay scores.

    Published on purpose. Read it, fix your data, then submit.

    24%Rights & provenanceCan you prove where it came from and licence it for training?
    20%ScarcityCould a buyer get substantially this for free?
    14%Process signalReasoning, tool calls and failed attempts — or only the polished result?
    14%FidelityAccuracy, label noise, and whether claims are checkable.
    10%Training-readinessSchema, encoding, duplicates, format. Cleaning time comes off your number.
    10%CoverageSpread across the space you claim to cover.
    8%RefreshFrozen archive, periodic drop, or live feed. Feeds price as subscriptions.

    Five ways to fail regardless of score

    Personal data — identifiable people, no lawful basis.
    No chain of title — you can't document how you got it.
    Somebody else's content — scraped or rights-reserved, repackaged.
    Already in the corpus — duplicated from what buyers already hold.
    Terms that forbid it — your own agreements block sublicensing.
    Fail one? — usually paperwork. The assay says which, then re-run.
    Do you take ownership of my data?

    No. The sample produces your assay, and nothing is listed until you press the button. A listing carries the description and the scores, never the data. Buyers contact you and you negotiate directly.

    How much should I ask for?

    Anchor on what it replaces. If a lab would otherwise pay experts to produce the equivalent, price against that — $30 an hour for reviewers up to $200 for specialist clinicians. Exclusivity roughly doubles the conversation.

    What if my dataset is small?

    Small and unique beats large and ordinary. A few thousand genuinely non-public records capturing expert judgement will get a meeting; ten million scraped listings won't.

    04 / THE INDEX

    Describe the data you need. In a sentence.

    Every listing has been through the same assay, so scores compare across sellers.

    The index is closed. Sellers list what they hold and what it's worth — reading that takes an account we can attribute to a buyer.
