Endpoints

GET /api/v1/predictions All upcoming matches with margin-free fair odds, estimated fair probabilities and any live value signal (best soft price above fair).

Fields

value.price_gap
detected.price_gap How far the best soft-bookmaker price is above the margin-free fair price, worked out before the odds are rounded: 0.07 means 7% above fair. The value block uses the current prices; the detected block, the prices when the flag was recorded. It compares two prices; it is not expected profit.

value.edge
detected.edge The same number as price_gap, under its old name. It stays so existing integrations keep working; new code should read price_gap.

status Where the price gap on the match stands now, with the same states as on the site: actionable — a gap of at least 1.5% at the current prices monitor — gap under 1.5%, monitor only expired — a gap we flagged earlier that the market has since closed unconfirmed — A gap was seen on a price older than 90 minutes; we only flag prices we have re-read recently. none — no value

Embeddable badge

Show our live record on your site or forum with two lines of HTML: value flags recorded when shown and sealed before kick-off, with their average CLV. The badge updates itself and links to the public track record — that link is the only attribution we ask for.
