Rate and plan limits
Requests per second, monthly active players, and what each plan includes.
Rate limits
Limits are per API key, per second:
| Requests / second | |
|---|---|
| Sandbox key (any plan) | 20 |
| Live key, Free | 20 |
| Live key, Starter | 100 |
| Live key, Growth | 300 |
| Live key, Scale | 1,000 |
| Enterprise | 2,000, or as agreed |
One request can carry up to 100 events, so batching goes a long way. Every response has RateLimit-Limit, RateLimit-Remaining and RateLimit-Reset (seconds); a 429 also has Retry-After.
Monthly active players
An active player is one who sent at least one live event this calendar month (UTC). Sandbox never counts.
| Plan | Active players included | Over the limit |
|---|---|---|
| Free | 1,000 | New players' events are refused with 402 player_limit_reached until the 1st. Players already active this month keep playing. |
| Starter | 5,000 | Nothing is blocked; extra players are billed at month end. |
| Growth | 25,000 | As Starter. |
| Scale | 100,000 | As Starter. |
Owners and admins see a warning in the dashboard at 80% and 100% of the Free cap.
