Fetch volume and outcome-pressure metrics for a contract
Returns aggregate trade metrics (volume, per-outcome volume split, trade count) for a single (provider, contract_id) over a lookback window, computed from Kairos’s own ingested trade store — same data source as /trades/history, not a live upstream proxy. There is no buy/sell-side breakdown: metrics are split by outcome (outcome_0/outcome_1) rather than trade direction, since trade direction cannot be reliably determined from exchange data for all providers.
Auth: requires the trade:read scope (admin/JWT bypass the scope check; API keys need trade:read), plus API access to the requested provider being enabled for API-key callers — 403 if disabled.
Staleness: if trigger_ingest=true and ingestion coverage for the window is low, the service triggers a backfill/ingestion job and reports it via the indexing flag on the returned metrics object.

}Authorizations
Credential client id (kairos_ck_...). Must be sent together with X-Api-Key and X-Api-Secret.
64-char hex API key.
64-char hex API secret.
Query Parameters
Venue identifier, matched case-insensitively against the live provider registry.
Provider-specific contract identifier. Empty or >128 chars returns 400.
1 - 128Lookback window in seconds, ending "now". Clamped to [3600, 86400] (1 hour to 24 hours).
3600 <= x <= 86400If true, triggers ingestion when coverage for this window is low, rather than computing metrics from partial/stale data alone.
Response
Aggregate volume/pressure metrics for the window.
Aggregate volume/pressure metrics. Split by outcome (outcome_0 vs outcome_1), not by buy/sell direction — trade direction is not reliably derivable from every provider's exchange data.
