}The response body shown here is a static example, not live data. After you click Send, your live result appears in a separate panel headed 200 OK. The panel under the status-code tabs is a fixed sample from the spec — its field values (fees, prices, sizes, IDs, timestamps) are placeholders. Use Send, or call the endpoint, for current values.
marketId (as a string). Data is served entirely from in-memory caches on the gateway and refreshed in-process from the oracle feed, so this endpoint is safe to poll at high frequency.
Notes:
markPriceis the price used for risk valuation (margin, liquidation, PnL) and can differ fromoraclePrice.sequenceronly advances from engine-sourced updates. Prices seeded via the HTTP ingestion path (which has no engine sequence yet) leavesequencerat its previous value (or0if none).
Query Parameters
Restrict the response to a single market. Accepts either the display name (e.g. BTC-USD, case-insensitive) or the numeric market id (e.g. 1). Omit to return every online market. An unresolvable value → 400. A filter naming an OFFLINE market returns an empty object, matching how the unfiltered response omits offline markets.
Example:
"BTC-USD"
Response
Live prices keyed by stringified marketId.
