+## request_remove_puzzle_subscriptions
+
+Removes puzzle hashes from the subscription list (or all of them if None).
+
+```python
+class RequestRemovePuzzleSubscriptions:
+    puzzle_hashes: Optional[List[bytes32]]
+```
+
+## respond_remove_puzzle_subscriptions
+
+Returns the hashes that were actually removed.
+

+```
+
+## request_remove_coin_subscriptions
+
+Removes coin ids from the subscription list (or all of them if None)
+
+```python

+```
+
+## respond_remove_coin_subscriptions
+
+Returns the ids that were actually removed.
+
+```python
+class RespondRemoveCoinSubscriptions:
+    coin_ids: List[bytes32]
+```
+
+## request_puzzle_state
+
+Requests coin states that match the given puzzle hashes (or hints).  
+When subscribe is set to True, it will add and return as many coin ids to the subscriptions list as possible.  
+When subscribe is set to True and mempool updates are enabled (can be done during the handshake) mempool update messages will be sent (including an initial MempoolItemsAdded message when you subscribe for the first time).
+Filter out spent, unspent, or hinted coins, as well as coins below a minimum amount.
+
+```python
+class RequestPuzzleState:
+    puzzle_hashes: List[bytes32]

+
+## respond_puzzle_state
+
+Responds with coin states that match the given puzzle hashes (or hints).
+
+```python

+    puzzle_hashes: List[bytes32]
+    height: uint32
+    header_hash: bytes32
+    is_finished: bool
+    coin_states: List[CoinState]
+```
+
+## reject_puzzle_state
+
+Reject request_puzzle_state in the event that a reorg is detected by a node, this is the only scenario it will be rejected like this.
+
+```python
+class RejectPuzzleState:
+    reason: uint8  # RejectStateReason
+
+
+class RejectStateReason(IntEnum):
+    REORG = 0
+    EXCEEDED_SUBSCRIPTION_LIMIT = 1
+```
+
+## request_coin_state
+
+Request coin states that match the given coin ids.  
+When subscribe is set to True, it will add and return as many coin ids to the subscriptions list as possible.  
+When subscribe is set to True and mempool updates are enabled (can be done during the handshake) mempool update messages will be sent (including an initial MempoolItemsAdded message when you subscribe for the first time).
+
+```python
+class RequestCoinState:

+    previous_height: Optional[uint32]
+    header_hash: bytes32
+    subscribe: bool
+```
+
+## respond_coin_state
+
+Respond with coin states that match the given coin ids.  
+This does not implement batching for simplicity. The order is also not guaranteed. However, you can still specify the previous_height and header_hash to start.
+
+```python
+class RespondCoinState:
+    coin_ids: List[bytes32]
+    coin_states: List[CoinState]
+```
