Open Settings in Cursor, VSCode or Claude Desktop and paste the key into the setup field as the guides above describe.

3

Test and use

Send a test prompt. If it does not work, message us on Zalo with your order code and someone will guide you step by step.

User guide

How to add your key to coding tools and check your remaining quota.

Getting your key after payment

  • Once the money arrives, your key or account appears right on the payment page; no need to message the shop.
  • The key is also saved under My orders, so you can see it again any time.
  • Or open Check order and enter the order code to see the key (logged in to the account that bought it).

Adding the key to your tool

  • For tools that read environment variables, set the variable holding the key, then restart the tool so it loads the new value.
  • For tools with a key field in their settings, paste the key into that field and save.
  • If your plan comes with its own gateway address, also set the base URL variable to that address; otherwise the tool calls the original provider directly and reports an authentication error.
  • Each tool names its variables differently; check the tool's documentation for the exact name.

Checking your remaining quota

  • Open the Usage check page, paste your key and press Check.
  • The Overview tab shows total requests, total tokens and the cost used.
  • The By day tab lists cost and tokens for the last 30 days.
  • The Over quota tab shows usage above the daily quota.

When something goes wrong

  • Authentication errors usually come from a key pasted with missing characters or a forgotten base URL.
  • For quota errors, check the Usage check page before reporting a problem.
  • Still not working? Contact us with your order code and the error the tool shows.
