}Operational status: per-symbol-per-category freshness with healthy/degraded/unhealthy classification + an overall aggregate.
Three states, and the difference matters:
Per-venue status
Alongside the per-symbol grid, the response carries avenues block: one entry
per venue with the state of each feed.
"venues": {
"deribit": { "chain": "on", "tape": "on",
"chain_symbols": ["BTCUSDT", "ETHUSDT"], "chain_contracts": 1910 },
"derive": { "chain": "off", "tape": "on",
"chain_symbols": [], "chain_contracts": 0 }
}
| Field | Meaning |
|---|---|
chain | Options chain aggregation for that venue: on, off or unknown |
tape | Live trade tape for that venue: on, off or unknown |
chain_symbols | Which symbols the venue is currently live on |
chain_contracts | Instruments it contributed on the last cycle |
on- enabled on the worker that owns that feed.off- registered but disabled, or no collector running.unknown- no fresh status was published. This is not a synonym foroff: it means we cannot currently see the feed’s state, and treating it as disabled would be a guess.
chain_contracts is what separates a healthy venue from a quiet one. A venue
reporting on with 0 contracts is enabled but delivering nothing, which a
bare on would hide.
Use this to interpret a zero in a per-venue response. A venue contributing
0
open interest on by_venue is not necessarily switched off,
it may simply list no contracts on that surface right now. This endpoint tells
you which it is.See also
