SkyState

Metering ​

SkyState meters authenticated state-route requests that count against the account's monthly API-request allowance.

What is Metered ​

Metered requests are:

  • project API-key requests to authenticated public-state routes
  • end-user bearer requests to user-state routes

Not metered against the monthly API-request quota:

  • anonymous SDK/browser reads from /v1/readonly/.../public-state/...
  • developer bearer requests, including console and CLI developer operations
  • project, account, billing, auth, health, and webhook routes

Anonymous public-state reads are not subject to standard HTTP rate limiting (only credentialed requests are), though cache behavior still applies; they do not increment the monthly API-request counter.

Monthly Counters ​

Counters are stored per account per calendar month. Each metered request increments the counter for the current month.

Reset Timing ​

The counter resets on the first day of each calendar month at 00:00:00 UTC. A new counter is automatically created for the new month on the first metered request.

Enforcement Thresholds ​

Two thresholds control enforcement:

  • Warning threshold (100%): at or above the limit, the over-limit indicator appears in the console.
  • Block threshold (110%): metered state-route requests are hard-blocked when the count exceeds 110% of the tier limit. This 10% grace buffer allows brief overages before enforcement kicks in. Blocked requests receive a quota error until the counter resets.

Over-Limit Behavior ​

When the block threshold is exceeded:

  • metered state-route requests fail with a quota error until the monthly counter resets
  • The console displays an over-limit banner with an upgrade prompt

The counter continues to increment even while blocked, so the count accurately reflects actual demand.

Reducing Request Count with Caching ​

The SDK uses HTTP caching for anonymous public-state reads. In production, public-state responses are cached for 15 minutes; in development and staging, they are cached for 10 seconds. Caching reduces network public-state fetches and improves latency, but anonymous public-state reads are not part of the monthly API-request meter.
