Put your own value in place of <WATSONX_API_KEY> (IBM Cloud API key (create one at https://cloud.ibm.com/iam/apikeys)). The author’s registry entry marks it as required.

Optional settings from the registry entry, left out of the block above: WATSONX_PROJECT_ID (watsonx.ai project id (Project → Manage → General → Project ID). Provide this or WATSONX_SPACE_ID), WATSONX_SPACE_ID (watsonx.ai deployment space id. Alternative to WATSONX_PROJECT_ID), WATSONX_URL (Regional inference host. Defaults to https://us-south.ml.cloud.ibm.com), WATSONX_MODEL_ID (Default chat/generation model id. Defaults to ibm/granite-3-8b-instruct), WATSONX_EMBED_MODEL_ID (Default embedding model id. Defaults to ibm/granite-embedding-278m-multilingual), WATSONX_API_VERSION (watsonx.ai REST API version date. Defaults to 2024-05-31).
