# Top Up Your A2Agent Account Balance and Manage Billing

> Add credits to your A2Agent account using USDT, Stripe, PayPal, or an overseas card. Your balance never expires and there is no monthly fee.

A2Agent uses a prepaid credit balance. You top up your account and credits are deducted as you make API requests. There is no monthly fee and your balance never expires, so you stay in full control of your spending without worrying about surprise charges or lapsing credits.

## Supported Payment Methods

A2Agent accepts a range of payment methods to accommodate users worldwide:

* **Stripe** — credit or debit card payments via Stripe's secure checkout
* **Overseas credit and debit cards** — international cards accepted directly at checkout

<Note>

## Developer vs. Enterprise Pricing

**Developer (pay-as-you-go)**

The default plan requires no commitment. You pay only for the tokens you consume at standard rates, with no monthly fee and no minimum spend.

**Enterprise**

Enterprise accounts unlock volume discounts, dedicated concurrency, higher rate-per-minute (RPM) limits, and access to 500+ model and provider channels. If your team has high-volume or latency-sensitive requirements, [contact the A2Agent team](https://a2agent.me/about) to discuss an enterprise arrangement.

## Refund and Balance Policy

* Your balance **does not expire** — credits you add today remain available indefinitely.
* There are **no automatic subscription charges**. Your balance is only reduced when you make API requests.
* For questions about refunds or billing disputes, email [patchx2025@gmail.com](mailto:patchx2025@gmail.com).

<Warning>
  All accounts, payments, and API usage must comply with your local laws and the terms of any third-party services involved. A2Agent serves users **outside mainland China** only. It is your responsibility to ensure your use of this platform is lawful in your jurisdiction.
