Get historical oracle (spot) prices for crypto chart pre-population
Returns per-symbol resolution-price history over [end_ms - minutes*60*1000, end_ms]
(end_ms defaults to now; clamped to now if a future value is given). Each request
names one oracle source so settlement feeds are never mixed. Symbols must be
the wire ids for that source (bare btc-usd for Binance;
btc-usd-polymarket-chainlink, btc-usd-kalshi-cfb, btc-usd-hyperliquid-mark,
or a -polymarket-twap30/-polymarket-twap60 suffix for venue series). When
source is omitted, it is inferred from the wire symbols — mixed sources are
rejected. Only Binance gaps may be backfilled from Binance REST; every other
source returns an empty array for a missing span. Responses are cached briefly.
The internal store can lag real time by a few seconds.

}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
Comma-separated, case-insensitive wire symbols for a single source.
Logical assets are btc-usd, eth-usd, sol-usd, xrp-usd, doge-usd, hype-usd,
bnb-usd; venue sources append their suffix (for example
btc-usd-polymarket-chainlink). Kalshi CF Benchmarks supports BTC, ETH, SOL, XRP, DOGE, HYPE, and BNB.
Resolution feed identity. Omit only for legacy clients that encode the source in the wire symbol; new callers should pass it explicitly.
binance, hyperliquid_mark, kalshi_cfbenchmarks, polymarket_chainlink, polymarket_twap30, polymarket_twap60 Minutes of history to fetch (max 24h).
1 <= x <= 1440Return raw 1-second history without downsampling.
End timestamp in epoch ms (clamped to server "now"). Omit for the live edge. Used for chunked/paginated backward loading.
Response
Price-history points per symbol, sorted ascending by timestamp.
Price-history points keyed by oracle symbol (btc-usd/eth-usd/sol-usd/xrp-usd), each array sorted ascending by timestamp.
