Line Gap supports six leagues today. The +EV scanner, line movement intelligence, sharp signals, and cross-book detection work for all of them. The Research Lab depth varies by sport — NBA is the most mature.

MLB is excluded by default from closing-line capture — high prop volume but low individual bet value, not worth the API spend right now. Configurable via the CLOSING_LINE_SPORTS environment variable.

Sport-specific notes

​
NBA

The original league; deepest Research Lab support. Pace analysis, defense-vs-position breakdowns at the position level (PG, SG, SF, PF, C), correlation matrix between teammates’ stats.

​
NFL

Player + defense-vs-position analysis active. Weather integration for outdoor games is on the roadmap.

​
NHL

Player props supported. Goalie-specific stats and power-play efficiency in the roadmap.

​
UFC

Fighter-by-fighter analysis. Method-of-victory props and round-of-finish props are live.

​
NCAAB / NCAAF

Player props and basic Research Lab support. The team and conference depth that exists in NBA / NFL is more limited here — sample sizes for college players are smaller and the meta turns over each season.

​
Coming soon

MLB

Excluded by defaultCurrently outside the closing-line capture allowlist due to API cost. Adding MLB requires either a higher Odds API tier or stricter prop-level filtering on which props we capture closes for.

Soccer / EPL / MLS

Not on near-term roadmapThe Odds API supports soccer leagues, but the prop-type taxonomy is wider and our Research Lab metrics don’t map cleanly. Future expansion.

WNBA

Tracked as enhancementSame data feed as NBA via The Odds API. Adding it is mostly a configuration change once we’ve validated demand.

Weather integration (NFL)

Tracked as enhancementWind / rain impact on passing and kicking props for outdoor games.
