Resolutions
Batch resolution fractions for up to 200 markets
Returns the resolved YES-side fraction (payout_numerators[0] / sum) for each requested market that has resolved; unresolved markets are omitted entirely from the response (never a guessed value). Providers are keyed either directly by market id/ticker (kalshi) or by their on-chain condition id (polymarket, predictfun, opinion). Rate-limit bucket: LIGHT.
For scalar/range markets with no payout numerators, the venue’s settled value is used as the fraction instead of a YES/NO split (kalshi-keyed providers only).
The response is ETagged (strong ETag) with a Cache-Control header; a matching If-None-Match returns 304.

}Authorizations
Credential client id (kairos_ck_...). Must be sent together with X-Api-Key and X-Api-Secret.
64-char hex API key. Must be sent together with X-Client-Id and X-Api-Secret.
64-char hex API secret. Must be sent together with X-Client-Id and X-Api-Key.
Query Parameters
Venue identifier. Any registered provider (including disabled ones, for historic reads).
Available options:
kalshi, polymarket, opinion, predictfun, hyperliquid, kalshi_offchain, dome Comma-separated market ids/tickers. Up to 200. Empty entries are dropped.
Response
Map of market_id to resolved YES-side fraction, for resolved markets only.
Map of market_id → resolved YES-side fraction (0–1). Markets with no resolution yet are omitted entirely — there is no null/false placeholder for "unresolved".
