14-Day Free Trial
Every paid plan (Starter, Professional, Enterprise) includes a 14-day free trial. No credit card is required to start a trial. During the trial, you have full access to your plan's features and quotas.
If you do not add a payment method before the trial ends, your account automatically downgrades to the Explorer plan. You will not lose any keys or data, but your quotas will be reduced to Explorer tier limits.
Overage Policy
Qpher uses hard limits for API call quotas. When you reach your monthly API call limit,
additional requests receive a 403 error with the message "quota exceeded." There are no
overage charges.
If you consistently hit your limit, consider upgrading to a higher plan. You can upgrade at any time from the Dashboard at portal.qpher.ai.
