AI subscriptions are expensive if you rarely use them
Most AI services charge you every month in dollars, require a credit card, and only work inside their own app. Vantenza AI is built for people who want something simple and affordable.

|---|---|---|
| How you pay | Monthly bill, renews automatically | Buy once, use until it runs out |
| Payment methods | Credit card, in dollars | QRIS, e-wallets, bank transfer (rupiah) |
| If you rarely use it | Still pay in full every month | Your quota stays the same |
| Where you can use it | Only in its official app | Chat apps, Google Sheets, code, plugins |
| Model options | Tied to one provider | Several models, pick what fits your needs |
| Tracking spending | Hard to know what is left | Remaining quota in rupiah, in real time |

How is quota deducted?
- 1
Counted per token
Tokens are pieces of words. Every question (input) and every AI answer (output) is counted in tokens.
- 2
Deducted little by little
A short chat usually uses only a few dozen rupiah. Long answers, large files, and smarter models use more.
- 3
Stops when it runs out
No extra charges. When your quota runs out, requests are declined and you simply buy more quota.
Usage per chat is an estimate and depends on the length of the question, the answer, and the model you choose.
Safe and transparent
Chat content is not stored on our servers
Your messages are forwarded to the AI provider for processing. Vantenza AI servers only record the number of tokens and the cost, not the content of your conversations.
An API key just for you
Every purchase gets its own API key with a quota limit, so usage never exceeds what you paid for.
Payments through Lynk.id
Transactions are processed by Lynk.id. We never ask for or store your card or bank account details.
Frequently asked questions
What is Vantenza AI?
Vantenza AI is an AI service you can use in a chat app, Google Sheets, or your own program. You buy quota once and use it until it runs out, with no monthly subscription.
I can't code. Can I still use it?
Yes. Our guide has a section just for beginners: install an AI chat app, paste in your API key, and start asking questions like a normal chat.
What do I get after paying?
A redeem code is sent to your email. Redeem it on the redeem page to get your API key, server address (Base URL), and model name, ready to use.
Does the quota expire?
Your quota does not go down if you do not use it. It only decreases when you send requests to the AI.
How do I know how much quota I have left?
Open the Check usage page and enter your API key. Your remaining quota is shown in rupiah, along with the number of tokens you have used.
Can I send images, video, or PDFs?
Yes, with models that support them (listed in the Models section). Generating images and speech is available through separate API endpoints (see the "More API features" section of the guide); generating video is not supported yet.
The redeem code email did not arrive. What should I do?
Check your Spam or Promotions folder. If it is still not there after a few minutes, contact us through the support email and include your proof of payment.
Can one API key be used in several apps?
