​
data

required
​
meta
V2Meta · object
required

The meta block returned alongside every v2 response.

Every field after version/timestamp is optional because endpoints attach different combinations — e.g. /v2/status skips symbol, the chain endpoint sets extra.filter_hash, etc. Listing them here means SDKs get a typed accessor for each instead of a generic meta: dict.
