No per-token USD billing, no international card needed. You buy a fixed quota package, and one key works across 26 models from Anthropic, OpenAI, Google, DeepSeek, Z.AI and xAI — for Claude Code, Codex, Cursor, Cline and any OpenAI / Anthropic compatible app.
| Package | Price | Quota | Validity | Unit price |
|---|---|---|---|---|
| Starter | $0.72 ≈ 19.000đ | 10M tokens | 1 day | 1.900đ / 1M tokens |
| Pro | $1.70 ≈ 45.000đ | 100M tokens | 2 days | 450đ / 1M tokens |
| Max | $5.25 ≈ 139.000đ | 500M tokens | 7 days | 278đ / 1M tokens |
| Ultra | $16.94 ≈ 449.000đ | 2B tokens | 30 days | 225đ / 1M tokens |
Prices are charged in Vietnamese đồng (VND). USD figures are shown for reference at the display rate of 26.500đ = $1; when you pay with USDT, the exact USD amount of your order is what counts. The unit price is the package price divided by its total quota — the bigger the package, the cheaper each 1M tokens. Per-model rates and the charging formula are on the Models & pricing page.
Every call is charged exactly what it used: input tokens × input price + output tokens × output price + cache tokens × cache price of that model. The final charge is then converted by calling route: Claude Code (Anthropic format, /v1/messages) ×4.1; chat and Codex (OpenAI format) ×2.25. Requests that fail on our side are never charged. Open the Check key page and you can see every call and exactly how much it charged — there are no hidden deductions.
The Starter package is enough to test every app and every model. When you are happy, top up — quota stacks onto your existing key, nothing is lost.
