KeepTradeCut vs FantasyCalc
KeepTradeCut and FantasyCalc price players by different routes; what differs in practice is workflow, terms and access.

| League sync | Not verified | Per-league import not verified | None |

KeepTradeCut
KeepTradeCut has visitors pick one of three assets, repeatedly, and turns those votes into a modified Elo rating. 1QB and Superflex are separate vote pools.
Rankings unlock after you vote, which keeps the sample large. No paywall, no public API; the terms forbid scraping.
FantasyCalc
FantasyCalc fits a regression to trades that actually closed in Sleeper, FleaFlicker and MFL leagues, millions by its own count: a market price rather than a consensus price.
The public API needs no key but is non-commercial, cannot substantially replace the site, and requires an attribution link. No paywall; Raptive ads, like KeepTradeCut.
Where TradeBalancer sits
A third route: FantasyPros expert consensus turned into a value curve by DynastyProcess. We publish it; we did not invent it. No league sync, and not the community's reference currency. Our source vs FantasyCalc: Spearman rank correlation 0.962 across 356 matched players (full table).
