Is that bet actually +EV after fees?

LineAgent is a verification engine for pick communities, odds tools and exchanges. Send it a price and it returns a clear verdict, the EV after fees, the fair odds, and a plain-English reason. It uses the same rules every time.

Verdict API

+EV or skip, EV % after fees, fair odds like -110 (52.4%), and the reason.

Exchange slip links

Novig and ProphetX links open the exchange's own slip. The user confirms there.

Boost pricing

Checks boosted straights and parlays against worst-case fair odds.

Verified scorecard

Graded record with closing-line value (coming in v1.1).

The rules (same as All Star on Linecast)

Pass only at EV ≥ 2% after fees, using the worst case of 4 devig methods.
Kalshi fee: ceil(0.07 × contracts × price × (1 − price)), applied before EV.
Spreads: only whole-number line gaps count. Totals and player props: half-point gaps are OK.
One pick per game per category. Pregame only. Odds window −150 to +150.
