🔑 GPT-Image-2 API Key Description

Securely store and manage MuAPI API key for GPT-Image-2 services, streamlining integration and enhancing convenience.

🔑 GPT-Image-2 API Key:

The GPTImage2ApiKey node is designed to securely store and manage your MuAPI API key, which is essential for accessing the GPT-Image-2 services provided by muapi.ai. This node simplifies the process of integrating your API key into various GPT-Image-2 nodes, ensuring seamless connectivity and functionality. By storing your API key once, you can easily wire it to any GPT-Image-2 node without repeatedly entering it, streamlining your workflow. Additionally, if you prefer not to manually input your API key, the node can automatically retrieve it from a configuration file located at ~/.muapi/config.json, which can be set up using the command muapi auth configure --api-key YOUR_KEY. This feature enhances convenience and security, allowing you to focus on creative tasks without worrying about authentication details.

🔑 GPT-Image-2 API Key Input Parameters:

api_key

The api_key parameter is a string input that represents your unique MuAPI API key. This key is crucial for authenticating your requests to the GPT-Image-2 services. If you provide a valid API key here, it will be used for all subsequent operations involving GPT-Image-2 nodes. The parameter does not support multiline input and defaults to an empty string if not specified. If left empty, the node will attempt to read the API key from the ~/.muapi/config.json file. This parameter ensures that your API interactions are authenticated and authorized, enabling you to utilize the full capabilities of the GPT-Image-2 services.

🔑 GPT-Image-2 API Key Output Parameters:

api_key

The output parameter api_key returns the API key that has been successfully loaded and is ready for use with other GPT-Image-2 nodes. This output confirms that the key is correctly configured and available for authenticating requests. It is a string value that represents the API key, ensuring that all subsequent operations can proceed without authentication issues. This output is crucial for verifying that the node has successfully retrieved or accepted the API key, providing confidence in the setup process.

🔑 GPT-Image-2 API Key Usage Tips:

  • Ensure that your API key is kept secure and not shared publicly to prevent unauthorized access to your MuAPI account.
  • If you frequently use multiple GPT-Image-2 nodes, consider configuring your API key in the ~/.muapi/config.json file to avoid manually entering it each time.
  • Regularly check the validity of your API key and update it if necessary to maintain uninterrupted access to the GPT-Image-2 services.

🔑 GPT-Image-2 API Key Common Errors and Solutions:

No API key found. Either paste your key into the api_key field, or run muapi auth configure --api-key YOUR_KEY in a terminal.

  • Explanation: This error occurs when the node cannot find a valid API key in the input field or the configuration file.
  • Solution: Ensure that you have entered a valid API key in the api_key field or configure it using the command muapi auth configure --api-key YOUR_KEY to store it in the configuration file.

Auth failed — check your API key.

  • Explanation: This error indicates that the provided API key is incorrect or invalid, preventing successful authentication.
  • Solution: Double-check the API key for any typos or errors. If the key is correct, verify that it has not expired or been revoked by checking your MuAPI account settings.

Insufficient credits — top up at muapi.ai.

  • Explanation: This error means that your MuAPI account does not have enough credits to perform the requested operation.
  • Solution: Visit muapi.ai to purchase additional credits for your account to continue using the GPT-Image-2 services.

Rate limited — please retry later.

  • Explanation: This error occurs when you have exceeded the allowed number of requests in a given time period.
  • Solution: Wait for a while before retrying your request. Consider optimizing your usage patterns to avoid hitting rate limits frequently.
