Great! Thank you very much. Grabbed the code and adjusted to me need where i only want to query one option. In case someone needs it as well:
add_action("rest_api_init", function () {
register_rest_route("options", "/clients", [
"methods" => "GET",
"callback" => "acf_options_route",
]);
});
function acf_options_route() {
return get_field('lmdm_clients','option');
}
lmdm_clients is a repeater field in this case…
