An API key (chance_sk_live_…) from https://harness.chance.cc/keys.
Body
The rules the action must satisfy: mandate, limits, thesis. Must be non-empty after trimming.
"Only buy favorites priced at or above 95c. No longshots. Max $10 per market."
The proposed action. A string is judged as written (mode: semantic). An object is classified by a venue adapter when one matches (mode: structured); an unmatched object is judged as JSON (mode: semantic).
"Buy YES on the Will-X-win market at 21c for $10."
Venue adapter to use. Ids: hyperliquid, limitless, polymarket, dimes, myriad, orderly, derive, lifi, meow, liquid, robinhood, x402, agentcards, uniswap, solana, starknet, alchemy. The value is lowercased, stripped of punctuation and matched against ids, aliases (hl, poly, evm, eth, base, sol, rh, lyra, ...) and id prefixes. An unknown value is ignored and object actions fall back to structural detection.
"hyperliquid"
Facts for the judge, shown as JSON under CONTEXT. context.reference is handled separately.
