Keyword arguments:
CURL-ARGS (optional) is a list of additional Curl arguments.
HOST is the Kagi host (with port), defaults to \"kagi.com\".
MODELS is a list of available Kagi models: only fastgpt is supported.
STREAM is a boolean to toggle streaming responses, defaults to
false. Kagi does not support a streaming API yet.
PROTOCOL (optional) specifies the protocol, https by default.
ENDPOINT (optional) is the API endpoint for completions, defaults to
\"/api/v0/fastgpt\".
HEADER (optional) is for additional headers to send with each
request. It should be an alist or a function that retuns an
alist, like:
((\"Content-Type\" . \"application/json\"))
KEY (optional) is a variable whose value is the API key, or
function that returns the key.
