## Choose access for the job

A timed plan covers eligible usage for its active period under fair-use limits. Prepaid credits suit occasional requests and work that does not fit a fixed session.

Current Claude Unlimited group rate limit: **60 requests per minute**. Model availability and your selected plan's expiry still apply.
 
 | Your workload | Start here | Before you start
 
 | A short test or one focused job | [One-hour paid plan](https://aiprimetech.io/plans/unlimited-claude-api-1-hour/) | Prepare your tool before the access period begins.
 
 | Regular coding or agent sessions | [Compare timed plans](https://aiprimetech.io/plans/) | Check duration, eligible group and limits.
 
 | Occasional API calls | [Prepaid credits](https://aiprimetech.io/learn/buy-claude-api-credits/) | Check the model's current usage pricing.
 

New paid access starts when it is granted to your account. Extending active access adds time to its existing expiry. Your account shows the exact end time.
