Always
"price_feed".Feed name (e.g.
"BTC/USD", "ETH/USD"). Top-level convenience field, same value as data.feed.Observation timestamp in Unix seconds. Top-level convenience field, same value as
data.timestamp.Notes
- Update rate: approximately 1 update per second per feed.
- No snapshot: unlike settlement subscriptions, price feed subscriptions do not include an initial snapshot. The first event arrives with the next price observation (~1 second after subscribing).
- Deduplication: if you subscribe to all feeds, BTC/USD may arrive at a slightly higher rate (~2/second) due to multiple upstream sources. Your application should deduplicate by timestamp if needed.
