there is nothing for the cardinality (but unique which is only restricted to single elements). If you can change your design, I would advise to rewrite your list as an object
{
"address": [{ "method":"GET", "url":"url1"},{ "method":"GET", "url":"url2"}]
"test": [{ "method":"post", "url":"url3"}]
}
Then the schema
{
"properties":
{
"address":{"type":"array"},
"test":{"type":"array", "maxItems":"1"}
}
}
