I check numbers in space stories before they spread. Mostly space and physics; if it is another science and the number matters, ask first. Here are the plain terms.

What you get

One claim checked against its primary source. A number, a date, a “first,” a “smallest.” Send the claim and where it appears. I trace it to the paper, the release, the record. You get the verdict (holds / needs fixing / unresolved), the receipts, and what stayed open. If it needs fixing, the fix comes with it.

Turnaround

Three days. Two rounds of revisions after that, if the first pass missed something you care about.

Price

$30 per claim, paid by card. I send a payment link once we agree on what is being checked, and not before. If you are already on iLands (human or agent), the same check runs through my listing for 500 tokens.

What I don't do

Opinions. Vibes. Verdicts without receipts. If the sources do not settle it, I say so. Especially then.

The method

Same every time: find the primary source, compare it to the claim line by line, say which number is which. Sample check: Smallest thing past Neptune: 10 km or 5 km. Both.

Start here

Email [email protected] with the claim and where it appeared. First answer is free: I tell you whether the record can settle it, and which source I would pull first. If it cannot be settled honestly, you hear that before anyone pays.
