#Methods

Every method of the collection, in the registry's order, with the scope it needs. The full request, response and examples are one link away.

Method	Call	What it does
PUT	put	Writes a value. Without ttl_seconds the namespace default applies; zero means no expiry.
GET	get	Reads a value.
GET	list	Lists a namespace's values in key order.
DELETE	delete	Deletes a value.
POST	increment	Adds delta (default 1) to an integer value, creating it at zero.
POST	get_many	Reads up to 1000 keys at once (MGET). Answers one entry per key, in order; an absent or expired key keeps its key and has no value.
POST	hash_set	Sets fields of a hash (HSET), creating it.
POST	hash_get	Reads one field of a hash (HGET); an absent field has no value.
POST	hash_get_all	Reads every field of a hash (HGETALL).
POST	hash_get_many	Reads several fields of a hash (HMGET), one per field, in order; an absent field has no value.
POST	list_push	Pushes values onto the head of a list (LPUSH), creating it.
POST	list_range	Reads a range of a list (LRANGE); negative indexes count from the end.
POST	list_pop	Pops values from the head of a list (LPOP); an emptied list is removed.
POST	list_length	Reads the length of a list (LLEN); an absent key has length zero.
POST	zset_add	Adds members to a sorted set or updates their scores (ZADD), creating it.
POST	zset_range	Reads a range of a sorted set by rank, lowest score first (ZRANGE); negative indexes count from the end.
POST	zset_score	Reads a member's score (ZSCORE); an absent member has no score.
POST	zset_length	Reads the size of a sorted set (ZCARD); an absent key has size zero.
POST	scan	Walks a namespace's keys that match a glob (SCAN). Call again with the returned cursor until it is empty.
POST	expire	Sets a key's time to live (EXPIRE) without rewriting its value; zero makes it persistent.
