"example": {
"as_of": "<UTC timestamp>",
"plans": [],
"product": "cpfp_budget_batch",
"terms": "A fee arithmetic estimate, not a transaction, broadcast, relay-policy validation or confirmation guarantee. Assumes one child spending an available output of the selected transaction and no additional unconfirmed inputs. Child size is buyer-supplied. Uses actual base fees of the observed transaction and its ancestors, excluding local fee deltas. Other miners and nodes can have different views and policies. Check output ownership, available value, descendants and package policy. Paid replay preserves the original snapshot; recheck current conditions before acting."
