Odds API by market / MLS
MLS Player to be Carded API
Live player_cards odds across every book that posts it, in one REST call — and, unlike any other odds API, every one of those outcomes settled against the official result once play ends.
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 6 October 2026.
Books posting MLS player to be carded
Measured live, not listed from a spec. Coverage moves — a book that has not put its board up yet will not appear until it does, which is exactly what this list is for.
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 21 days
13.6% of 708 settled player to be carded legs hit (96 yes, 612 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 708 YES legs out of 986 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 Vancouver Whitecaps @ Chicago Fire, 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.
