Updated on 01 Oct 2025

1. Sign Up / Log In

  • Go to: https://marketplace.fptcloud.com/en
  • If you don’t have an account yet, click Sign up and complete the registration form (email, password, name, etc.).
  • Verify your account via email if required.

2. Go to User Dashboard

  • After logging in, open My Account.
  • In the account page, find the My API Key section.

3. Create a New API Key

  • Click Create new API Key.
  • The system may ask you to:
    • Select models you want this API Key to access.
    • Name your API Key for easy management.
  • Click Create.
  • Your new API Key will appear in the list.

4. Copy and Manage Your API Key

  • Copy the generated API Key and use it in your apps.
  • You can view, manage, or delete API Keys in the My API Key list.
  • If needed, you can revoke an API Key.

5. Use the API Key in Your Application

  • When calling an API, include the API Key in the request header:
Authorization: Bearer 
  • Example: if integrating with tools like Cursor IDE, paste the API Key into the “OpenAI API Key” field, enable override URL if needed, and verify.
  • Once validated, you will see “Verified Successfully”.

🧠 Tips & Notes

  • Keep your API Key secret – never expose it in public repositories or shared code.
  • You can create multiple API Keys for different projects.
  • If your API Key is leaked or misused, revoke it immediately.
  • Monitor your usage, tokens, and costs in the Marketplace dashboard.
  • If you see errors like “invalid api_key”, check:
    1. Whether the API Key is correct.
    2. Whether the API Key has access to the selected model.
    3. Whether you placed it in the correct request header.
