[02]Why it matters
Fake jobs are a half-billion-dollar problem.

Scammers don't need you to believe everything. They need one small step: reply on Telegram, deposit the check, buy the laptop. ProofBeforePay checks the offer before you take it.
[03]How it works
Seven steps, three Nemotron models, and a verdict that has to survive an argument.
Each investigation runs the same seven steps. Code handles what code is good at, Tavily brings in the web, each Nemotron model gets the work that fits its size, and a second model tries to prove the first one wrong.

[04]Model routing
Small models do the legwork. Ultra makes the call.
Nano takes the quick, frequent jobs. When Nano isn't sure about a claim, Super checks it again with a fresh search. Ultra reads everything once and decides. Every call is metered, so each report shows its real cost next to what the same tokens would have cost on Ultra alone.

[05]What you get back
A decision you can act on, and the receipts.
Not a score with no explanation. You get a clear call, what not to do yet, a reply you can send, every piece of evidence behind it, and the strongest case against it.
Should you take the next step?
Stop.
The equipment check is a known fake-check pattern, and the sender's domain was registered nine days ago.

Argued with, every time

[06]Honest by design
Built to be careful, not just confident.
A wrong “this is a scam” can cost someone a real job. A wrong “looks fine” can cost them their savings. These rules are enforced in code.
- 01
Missing evidence isn't proof of fraud.
If the web has nothing on a company or a person, the claim is marked inconclusive. It is never counted as contradicted.
- 02
Quotes are checked against the page.
A quote only appears in the report if those exact words are on the source it cites.
- 03
Money requests can't get a green light.
If the message asks for money, a rule in code blocks a Proceed verdict, whatever the model says.
- 04
Signals, not accusations.
It never calls a company or a person a scammer. When a brand is being impersonated, the real company isn't the one at fault.
