: Unix timestamp of the request (in milliseconds)X-Variational-Key
: client API keyX-Variational-Signature
: a signature derived from the timestamp, client API key, secret, some of the request parameters and payload

Python SDK Latency Example:
ts_before = time.time()
response = client.get_portfolio_assets(pool="10e91774-34eb-4472-86c0-c910a22a4656")
assets = response.result
latency_s = response.meta.request_received_at - ts_before
