Used to power

01 · Watch the game

Score and clock update

The match is live — state stays attached to every price.

02 · Prices move

Books and exchanges reprice

Sharp, soft books, Kalshi, and Polymarket on the same game ID.

03 · Edge appears

Signals re-rank in real time

+EV climbs or falls as the fair line and offered price diverge.

What’s in the API

One contract.
A full sports stack.

Prices, edges, and game state — over REST, realtime, or MCP. Same auth. Same game IDs wherever you call.

What you ship with. How we join books, exchanges, and scores is next — so you do not have to.

Under the contract

Scattered feeds become one game.

Books, exchanges, and sports state lock onto one evt_…. Fair, +EV, and gaps are calculated there — then delivered through the API above. You don’t rebuild ingest, matching, or vig math.

Why the join matters

Stop stitching three vendors into one screen.

Most stacks split sports data, books, and prediction markets. Scoreline already puts them on one game — so your product doesn’t spend weeks remapping IDs.

When the line moves, the edge is already ranked.

+EV, middles, and book↔exchange gaps aren’t homework — they’re fields that update as quotes tick, then the board re-ranks.
