There is no price.

The reason

Nothing here is worth charging for yet

That is a statement about the data, not modesty about the engineering. The chain works — a frozen contract, a snapshot taken against it, the exact delta between two snapshots, and a receipt at every link. What flows through it is invented, and a working mechanism carrying invented values is worth what an invented value is worth.

Three things would have to be true before any amount could be set. Not one of them is a matter of deciding to charge.

• Real observations, ingestedNot one measured price, rent or listing count has ever been published from this product, and no provider feed is authorised. A tier selling access to observations needs observations to sell access to.Not true today
• Licence gating enforced by a mechanismA source whose licence forbids commercial use must be unable to enter a paid tier — by something that throws, not by someone remembering. Half of that exists today: NSW Valuer General bulk sales information is CC BY-NC-ND, its recorded assessment is NO-GO, and its kill switch is disabled by default, so the source is not ingested at all. That is a gate on ingestion. There is no gate on tiers, because there are no tiers.Half true
• Coverage stated as quantitiesA buyer is owed the extent of what they would be buying as a count rather than as a region name. Suburb boundaries are New South Wales only; roads and lots are five NSW postcodes; New Zealand stops at region outlines. Those quantities are already published on the data page, and they are the ones an amount would be attached to.True today

There is a fourth obstacle and it is mundane. Charging by usage requires counting usage, and nothing here counts anything — no meter, no quota, no key, no account, no record that a thing was read. A service that cannot count cannot charge by volume, whatever anyone intends.

A NonCommercial source can never enter a paid tier, and moving it to a free tier is not a remedy. NonCommercial attaches to the purpose of the use, not to the price charged for it.

The shape

What a tier would cap, and what it never would

The shape below is a choice, not an inheritance. The board this product renders derives from World Monitor, and an earlier draft of this page claimed that product's free tier caps how much you can have open rather than what you may do. That was wrong, and it was wrong in the flattering direction. Its source defines eleven panel types withheld by name, renders an Upgrade to Pro lock on them, and answers an unidentified caller with Sign In to Unlock — a wall in front of the door, on those eleven. Its paid tier also sells capability outright: API access, alerting, integrations. This product's own research note said as much and the draft contradicted it. So: the axes below are what we would choose, and the reason to prefer them is argued here rather than borrowed from someone else's practice.

Every cap above is deliberately numberless, and that is not coyness. The number falls out of what a licensed feed costs to serve; no feed has been procured; a cap chosen without that input would be invented in exactly the way this site refuses to invent things. The borrowed model's own figures are its commercial configuration and not DwellDelta's, so they are not reproduced here.

Refusals

A gate that does not say why is a defect

This product already refuses things in public. Five layers appear on the board with nothing drawn under them and a written reason attached, because a reader who cannot see that a thing was considered has no way to tell it apart from a thing nobody thought of. The vocabulary a tier gate would need already exists here — it is the vocabulary for an absent source.

needs a real sales-history source; none is authorised. The synthetic history above shows the shape this would take.

The board's own text for a layer it will not draw, carried from the layer registry rather than rewritten for this page

A tier gate would be that sentence with a different noun in it: what is unavailable, why, and what would change it — rendered in the place the thing would have been, rather than as a lock icon or as silence. The wording is not drafted and does not appear on this page. An unbuilt gate with published copy is a promise wearing a product's clothes, and the page for agents refuses the same trade for the same reason.

The line that does not move

Charging to check the data would make this an ordinary property site

The whole argument here is that a figure can be followed back to a contract, a snapshot and a delta. Put that behind a payment and what is left in front of it is a set of confident numbers nobody can trace — which is the thing this product was built in reaction to.

• It is the argument, not a feature of itA reader who can check the data is a reader who can be convinced by it. Metering the check meters the argument, and leaves a free tier indistinguishable from every other property site.Free
• It cannot leak values, by designThe position already recorded is that a provenance answer describes sources, licences, coverage and limitations and never returns an observation value. That is what makes it safe to leave unmetered: a provenance channel carrying values would be a bulk extraction path with a decorative meter on it.By design
• It is where the unflattering facts liveCoverage that stops, licences that forbid, and a count of real observations that reads zero. Charging for those would be charging a reader to find out what they are not getting.Free

The draft that disagrees

Internal research argues the opposite shape

The shape above is borrowed from a product whose feeds are public and cheap to serve. Property data is licensed and metered, and a second piece of internal research says plainly that copying the first shape without copying its cost structure is the most expensive mistake available here.

Their marginal cost is near zero; ours is not. A generous free tier here loses money per user, and copying the shape without copying the cost structure is the single most expensive mistake available.

Internal advisory research on subscription models — non-binding, and it decides nothing

Two drafts, pointing opposite ways, both recorded, neither ratified. That is published rather than resolved into a cleaner story, for the same reason the data page publishes two opposite licence calls: a project that recorded only the convenient one would be easier to describe and worth less. Nothing settles it until the input that decides it — what a real feed costs to serve — is a figure somebody has actually been quoted, and no feed has been procured.

The other thing on this site

The method has no price either, for a different reason

The services page offers a method rather than the product — a licence read and recorded before use, coverage stated as a count, every input hashed, claims sized to their evidence, applied to a register an organisation already holds. It states no amount, and the reason is not the one above.

Work is priced from work delivered, and that page opens by saying no integration has ever been delivered. There is no first engagement to have learned from, so any figure would be a guess with a decimal point in it. The two absences are different and neither is a negotiating position: one is missing data, the other is missing history.
