ComfyUI Node: Claude API

Claude API:

The AV_ClaudeApi node is designed to facilitate seamless integration with the Claude API, a powerful language model API provided by Anthropic. This node allows you to connect to the Claude API using your API key, enabling you to leverage advanced language processing capabilities for various creative and functional tasks. By configuring this node, you can generate text, perform language understanding tasks, and integrate sophisticated AI-driven interactions into your projects. The primary goal of this node is to provide a straightforward interface for accessing the Claude API, ensuring that you can easily incorporate its functionalities into your workflows without needing extensive technical knowledge.

Claude API Input Parameters:

claude_api_key

The claude_api_key is a string parameter that represents your unique API key for accessing the Claude API. This key is essential for authentication and authorization purposes, ensuring that your requests to the API are secure and properly attributed to your account. If you do not provide this key directly, the node will attempt to retrieve it from the environment variable CLAUDE_API_KEY. Without a valid API key, the node will not function, and an error will be raised. This parameter does not have a default value and must be provided by you.

endpoint

The endpoint is a string parameter that specifies the URL of the Claude API endpoint. This is where your requests will be sent to interact with the API. The default value for this parameter is https://api.anthropic.com/v1, which is the standard endpoint for the Claude API. You can change this value if you need to point to a different endpoint, but in most cases, the default should suffice. This parameter ensures that your requests are directed to the correct server for processing.

version

The version parameter is a string that indicates the version of the Claude API you wish to use. The available option for this parameter is 2023-06-01, which is also the default value. Specifying the version ensures that your requests are compatible with the API's expected input and output formats, and it helps maintain consistency in your interactions with the API over time.

Claude API Output Parameters:

llm_api

The llm_api output parameter represents the instance of the Claude API that has been configured with your provided settings. This output is crucial as it encapsulates the connection details and authentication information required to make subsequent requests to the Claude API. By using this output, you can perform various language model operations, such as generating text or understanding language, within your projects. The llm_api output ensures that you have a ready-to-use interface for interacting with the Claude API.

Claude API Usage Tips:

• Ensure that your claude_api_key is kept secure and not shared publicly to prevent unauthorized access to your Claude API account.
• Use the default endpoint value unless you have a specific reason to change it, as this ensures compatibility with the standard Claude API server.
• Always specify the correct version to avoid any issues with API compatibility and to take advantage of the latest features and improvements.

Claude API Common Errors and Solutions:

Claude API key is required.

• Explanation: This error occurs when the claude_api_key parameter is not provided and the environment variable CLAUDE_API_KEY is also not set.
• Solution: Ensure that you provide a valid claude_api_key either directly in the node's input parameters or by setting the CLAUDE_API_KEY environment variable.

Invalid endpoint URL.

• Explanation: This error may occur if the endpoint parameter is set to an incorrect or unreachable URL.
• Solution: Verify that the endpoint URL is correct and accessible. Use the default value https://api.anthropic.com/v1 if unsure.

Unsupported API version.

• Explanation: This error occurs if the version parameter is set to a value that is not supported by the Claude API.
• Solution: Ensure that the version parameter is set to 2023-06-01, which is the supported version as per the provided context.
