GPT API-abonnement
GPT API Pass: gratis proefversie en abonnement
- APIMaster offers a free GPT API trial and GPT API subscription plans with official-price GPT usage.
- Wallet billing automatically takes over after your GPT trial or GPT API subscription allowance is exhausted.
- Personal use only. No resale or sharing; violations will result in account suspension.
- Limited to 100 subscriptions. Removed once sold out.
How This GPT API Subscription Works
- 01
Start with a free GPT API trial or choose one 30-day plan
You can claim the free GPT API trial first, then choose the GPT API subscription tier that matches your expected workload.
- 02
Usage is checked in two rolling windows
Every successful GPT request counts toward both the previous 5 hours and the previous 7 days. Reaching either allowance pauses subscription billing for new requests.
- 03
Wallet balance provides fallback
After a GPT trial or GPT API subscription allowance is reached, supported requests can continue using wallet balance at the applicable API price, provided the wallet has enough credit.
Subscription and account-use rules
- GPT API subscriptions are for the subscriber's own use. Resale, credential sharing, and pooled account use are prohibited and may result in account suspension.
- Paid upgrades take effect immediately. Eligible unused value from the current plan is applied to the new plan; it is not returned to a wallet or payment method.
Free GPT Trial and GPT API Subscription FAQ
Is there a free GPT API trial?
Yes. APIMaster offers a free GPT API trial for eligible users, and the trial is billed at official GPT prices within the stated allowance.
How much does a GPT API subscription cost?
Pricing depends on the plan tier shown in the live catalog on this page. Each GPT API subscription includes rolling 5-hour and 7-day official-price usage allowances.
How do the 5-hour and 7-day rolling limits work?
At each request, APIMaster checks successful official-price usage during the immediately preceding 5 hours and 7 days. The request can use the subscription only when both windows have remaining allowance.
What happens when the free GPT trial or subscription allowance runs out?
When either rolling limit is reached, new supported requests fall back to wallet billing. If the wallet has insufficient balance, the request is rejected for insufficient quota.
Can I share or resell a GPT API subscription?
No. Every GPT API subscription plan is for the subscriber's own use. Reselling access, sharing credentials, or pooling one account across multiple users is prohibited and may lead to immediate suspension.
Which GPT API models are included in the GPT API subscription?
The supported models are shown in the live catalog on this page. APIMaster can update the model allowlist as models become available or change.
Does unused allowance become wallet credit?
No. The 5-hour and 7-day amounts are rolling usage limits, not stored wallet credit. They cannot be withdrawn, transferred, or refunded as cash.
