The exchange
Share data, unlock more
Every county published here is free to download and always will be. Credits are the other half of the site: contribute a county dataset and you earn them, then spend them on the things that aren't free — fresh vintages, unopened community uploads, and downloads without the ads. 1,689 counties currently pay more than the standard award for the data nobody has yet.

How the loop works
What earns credits
Upload a county's parcel layer. It runs through containment, schema and vintage checks before anything is awarded.
- Upload passes the automated checks Geometry lands inside the county, schema and vintage hold up. +10
- Upload matches a reference copy Machine-comparable to a known-good version of the county. +40
- Upload verified by review No reference existed, so a person confirmed it. The most valuable case. +75
- The county has a bounty open Multiplies the award above, by how badly the county is wanted. ×2 – ×5
- You judged a dataset right Endorse or report what you open; paid only when a reviewer agrees. ×2 the spend
- Create an account Enough to open something and see how it works. +5
What credits buy
Nothing on this list is something you need. Published counties are free to anyone, with or without an account.
- Any published county The whole free catalog. Costs an email confirmation and some ads, not credits. Free
- The same download, without the ads The data stays free; skipping the funnel is what costs. −3
- An unverified community upload Passed the checks, not yet confirmed. Honest uncertainty, priced accordingly. −15
- A premium county A current vintage that is not part of the free release. −250
Why one county pays more than another
Bounties are computed nightly from coverage state, not curated. The multiplier tracks how hard the county is to get and how expensive it is to verify once it arrives.
×3.5
No reference copy to verify against
Nothing exists here to check an upload against, so confirming one takes a person rather than a machine. Hardest to get, dearest to verify, best paid.

Newest version is stale
There is a snapshot, but it has aged past the point where it is safe to work from. A current one supersedes it.

How a bounty closes
A nightly job reads coverage state and opens a bounty where there is no dataset at all, where the newest snapshot has aged past the staleness threshold, or where enough people searched for a county the site could not serve. Nobody hand-picks a county and nobody bids.
The multiplier applies to the standard upload award and stops applying the moment a version for that county reaches verified status — so the first person to fill it takes the premium, the county opens for everybody, and the site stops paying for data it now has.
