CrashScores API
A free, read-only REST API that delivers real-time results for live shows and crash games. The goal is simple: give you the live outcome of each round as it settles. Four games are available publicly today, with more to come. Access is free in exchange for one followable link back to CrashScores from your homepage.
What the API Provides
For every round you get the result, the multiplier, the number of winners and the total payout with currency - delivered in real time as each round settles. New rounds land roughly every 25 to 80 seconds depending on the game.
Read the API Terms & License First
Before you build, please read the API Terms & Data License. It is the full rulebook for using the API: what you may and may not do with the data, caching and redistribution, the rate and daily limits, and - the one hard requirement - a visible, followable link to CrashScores on your homepage. Free keys are issued and stay active only while that link is live.

Rough Budget for a Typical Integration
New rounds land every ~25 seconds for the fastest game to ~80 seconds for the others. Because the list endpoint always returns the most recent rounds, you never lose a round by polling slower than they arrive - a single poll with a big-enough limit covers everything since your last one.
Polling all four games once a minute is 4 x 60 x 24 = 5,760 requests/day - comfortably inside the 10,000/day quota, and it never misses a round (set limit to ~25 to cover the fastest game between polls). Polling every 30 seconds (~11,500/day) would blow the quota, so poll about once a minute and cache in between.
If you also pull full detail per round, budget one extra request per round: the four games together settle on the order of ~7,000 rounds/day, so fetch detail only for rounds you actually need using the round_id from the list.
Every key is tied to one domain and stays active while your homepage link is live. Need higher limits or commercial terms? Get in touch.
Get Your Free Key
Enter your site's domain, add a link to CrashScores on your homepage, then verify to get your key.
Authentication
Send your key in the X-API-Key header on every request. Keys are tied to your registered domain (browser requests must originate from it), rate-limited per the limits above, and rotated by re-verifying your domain.
