Odds API by market / MLS
MLS Player to be Carded API
The player_cards board is not posted right now. This page keeps the last measured window — 1,963 settled outcomes — and reactivates on its own the first build after books post the market again. The endpoint, the response shape and the free tier work today.
No credit card. 1,000 requests / day on the free tier.
What MLS player to be carded is
Will this player be booked. Priced off referee tendency and fixture temperature as much as off the player, which is why it moves on the referee appointment.
How we settle it. Graded from the player's yellow and red cards in the match. A second yellow is not counted twice.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 7 November 2026.
Books that last posted MLS player to be carded
Measured on the last slate that carried it, 7 November 2026. When books post it again, this list rebuilds from whichever ones actually do.
Line shopping across all of them is one request — every book arrives in the same bookmakers array, not one call per book. Add ?bookmakers= to narrow it, or use /best-line for the best price per line already ranked.
Recently settled MLS player to be carded outcomes
These are real rows out of the API, not an illustration. Each one was a price on a board before the event and carries the actual figure it was graded against afterwards. No other odds API returns that last column — they stop at the price.

Hit rate, last posted window
13.9% of 1413 settled player to be carded legs hit (196 yes, 1217 no). Counted on the YES side only — books that price this two-way contribute their Over leg, not both. That is the base rate across the whole priced field, not a per-player figure.
Read off 1,413 YES legs out of 1,963 settled outcomes on this market. The rest are the Under side from books that price it two-way, which answers a different question.
Per-player hit rates and L5 / L10 / L20 splits live on /trends.
Live response
Captured from the real endpoint on Charlotte FC @ Inter Miami while it was posted, trimmed to one book and three outcomes so the shape stays readable. The full response carries every book and every line, alternates included, in the same call.
