Rate limits
Lumin meters per day, per identity. The reset is wall-clock UTC, not rolling.
| Tier | Limit | Scope | Endpoint |
|---|---|---|---|
| Anonymous | 50 / day | Per IP | /mcp |
| Free (OAuth) | 100 / day | Per account | /mcp/auth |
| Starter | 500 / day | Per account | Both |
| Pro | 5,000 / day | Per account | Both |
| Enterprise | 25,000 / day | Per account | Both |
Reset window
Daily limits reset at 00:00 UTC. There is no rolling-window meter, which means a high-volume burst right after the reset is fine, and a burst right before it is not.
Failed calls do not count
Errors with HTTP 4xx or 5xx do not consume budget. This makes retry loops safe and pre-flight validation cheap. Only successful tool responses count.
Admin overrides
Tier limits are configurable per key by Lumin admins via the system config table. If you have an enterprise relationship and need a custom limit, the override is per-key, not per-account.
