The hardest question in selling data isn’t how — listing takes ten minutes — it’s what. Most sellers guess. They shouldn’t have to, because buyers on datapoint.market literally write down what they want and can’t find.
The board
Every zero-result search on the marketplace is logged automatically as a
search miss — the single strongest supply signal that exists, because it’s
a buyer with intent hitting a gap in real time. Explicit asks arrive through
the seek_data connector tool or the public
form — anonymous, no account — and everything lands on the public
requested-data board.
At the time of writing, the board carries asks like:
- Hourly EU electricity spot prices, 2020–today — EPEX/Nord Pool day-ahead, parquet preferred, buyer states $25 per download;
- Japanese trademark filings, weekly;
- Antarctic krill biomass.
Look at the first one: format specified, price stated, delivery preference declared. That’s not a lead — that’s a purchase order waiting for a seller. Public spot-price data exists; the work being paid for is the assembly (one clean parquet, 2020–today, maintained). Someone with an afternoon and a scheduler owns that ask.
How to build against an ask
- Check the board before inventing a listing. Asks carry format and price expectations — the product spec is written for you.
- Assemble and list. For a file,
create_datasetwith one link is enough — the platform streams it, any size to 512 MB, payout non-custodial. - Declare the join handles. An ask like “spot prices” is really “spot
prices my agent can join to its portfolio table” — a
join card (“one row per bidding-zone-hour,
zoneis an EIC code,tsis ISO 8601 UTC”) is what makes your listing land inside the buyer’s fusion plan. - The asker gets notified. Asks with an opt-in contact are pinged when a matching listing appears — the demand loop closes itself.
Fusion-shaped demand is coming
Since join cards launched, a new kind of gap is
visible: an agent searching joinable_on="gtin" and finding nothing is
demand for a bridge — data keyed the way buyers hold their own data. Watch
for asks that name a handle; they tell you not just what data to sell but
what card to write.
Why this works better than guessing
A marketplace’s demand board is the cheapest market research in the industry: the buyers are pre-qualified (they searched, with a wallet connected), the spec is explicit, and the platform routes them back to you when you ship. Selling data used to start with “what do I have?” — it works better starting with “what are they asking for?”
