Limits

Per-IP rate limit source IP
· per 1 minute
15/1 minute
Per-domain ingest one registered domain, all visitor IPs together
· per 1 second
Domain freeze registered domain
· per 10 consecutive seconds at the plan ingest cap
Shared ingest cap all domains, platform-wide
· per 1 second
40/1 second
History API soft cap per site (per Private API Key)
· per 1 second
15/1 second
Deliberately sized so a 1:1 identify-to-History-lookup pattern stays inside the ceiling on Scale, whose ingest cap is also 15 RPS. This surface was recorded as "not rate limited" in the previous pass, which is no longer true.
Concurrency cap whole gateway, in-flight connections
· per instantaneous
