Docs / Rate Limits & Quota

Rate Limits & Quota

Plan quota is counted by request count, over a 5-hour window and a weekly window; token usage has no separate cap.

5-hour window

Rolling window, auto-resets. Over the limit = temporary throttle until reset; no charge.

Weekly window

7-day fixed window, same behavior.

Concurrency

Each plan has a concurrency cap; agent clients (Claude Code / Cline) are concurrency-heavy and may hit 429.

See exact numbers on the pricing page. To see usage live in Claude Code: Usage in Claude Code.

What a 429 means

concurrency_limit: concurrency over your plan cap — slow down / reduce concurrency, or upgrade / enable API credit billing.
window/quota: 5h or weekly window exhausted — wait for reset or upgrade.
upstream_busy: transient upstream load — usually clears shortly.
