Prepaid AI API credits
Every model. Provider price. Zero markup.
One API key for 284 models from OpenAI, Anthropic, Google, Mistral, DeepSeek, Qwen and more. Load credit once, call any model, and pay exactly what the provider charges per token.
API key in seconds, no card. Credit packs from $5. Credit never expires.
How it works
Three steps to your first call
Get an API key
Create a key on the Get API key page. No email, no card, no subscription.
Add credit
Buy a credit pack: Mini $5, Maker $19 or Studio $59, paid through Stripe’s hosted checkout. New keys start at $0, so calls need credit.
Call any model
Point any OpenAI-compatible client at https://api.tokenctr.com/v1. Each call is charged at the model’s own input and output rates.
Pricing
You pay what the provider charges. Nothing more.
Every model is billed at its provider’s published per-token price: input tokens at the input rate, output tokens at the output rate. When a provider reports extra charges for a call (cached prompts, web search, reasoning), you pay that reported cost too, with no markup on any of it.
- No subscription, no seats, no monthly minimum.
- Credit is in dollars and never expires.
- Your account page shows what every call cost.

Works with the OpenAI SDK you already use
TokenCenter speaks the OpenAI chat completions format. Change the base URL and the key, pick a model id from the catalog, and you’re done.
- Base URL:
https://api.tokenctr.com/v1 - Endpoint:
POST /chat/completions - Auth:
Authorization: Bearer <your key> - Every response includes a
usageblock with token counts.
"stream": true works and returns standard OpenAI chunks; the reply arrives in one burst once it’s complete.

FAQ
Common questions
Is there really no markup?
Yes. Each call is charged at the provider’s own per-token price. Card processing is already included in the pack price.
Do I pay for an API key?
No. Getting a key takes seconds, with no card. New keys start with $0 of credit, so you’ll need a credit pack before model calls go through.
Does my credit expire?
No. Packs are one-time purchases of dollar credit. There are no subscriptions or renewals.
Will it work with my existing tools?
If your tool supports the OpenAI chat completions format, yes. Set the base URL to https://api.tokenctr.com/v1, paste your key and choose a model id.
Do you store my card?
No. Payments happen on Stripe’s hosted checkout page. We never see your card number.
