STREAM is a boolean to toggle streaming responses, defaults to

PROTOCOL (optional) specifies the protocol, https by default.
ENDPOINT (optional) is the API endpoint for completions, defaults to
\"/v1/messages\".
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 is a variable whose value is the API key, or function that
returns the key.
CONTEXT and SOURCES: if true (the default), use available context
and provide sources used by the model to generate the response."
