API
Rate limits
How many requests you can send, per account and per IP — and why paid accounts have no request-rate limit at all.
Rate limits
These limits apply to the API: /v1/chat/completions, /v1/messages,
/v1/responses and /v1/images/generations. Web chat has its own, listed on
Web chat limits.
Paid accounts
An account with an active Pass, or any account that has topped up its wallet, has no requests-per-minute or requests-per-hour limit.
Free accounts
- 60 requests/minute and 1,800 requests/hour per account, shared across all your API keys and all models.
- 100 requests/minute and 3,000 requests/hour per IP address.
- Image generation: 10 requests/minute and 150 requests/hour.
- The free promotional models have no extra per-model limit — only the account limits above.
Concurrency
There is no limit on concurrent requests, on any plan.
What counts as a request
Each API call is one request. In agent tools — Claude Code, Codex, Cursor, opencode and the rest — every tool-call round trip is its own call, so a single task can use several requests.
When you go over
You get HTTP 429 with a Retry-After header. Wait that many seconds and
send the request again; the agent tools above do this for you.
Key limits are spending caps
The limits you set on an API key in the dashboard are caps in USD, not request rates. They stop a key once it has spent that much.
