Market Discovery — List and search prediction markets via REST API with filters for status, category, and featured flag.
Price Quoting — Get real-time LMSR prices for YES/NO shares via on-chain read-only calls before committing funds.
Trading — Buy YES or NO shares with slippage protection (
```
buy-yes-auto
```
,
```
buy-no-auto
```
). Sell with minimum proceeds guard (
```
sell-yes-auto
```
,
```
sell-no-auto
```
).
Redemption — Redeem winning shares after market resolution (1 share = 1 STX for winners).
Position Tracking — Check your YES and NO share balances in any market.

All operations are mainnet-only. Write operations (buy-yes, buy-no, sell-yes, sell-no, redeem) require an unlocked wallet (use

bun run wallet/wallet.ts unlock

first).

Notes

All operations are mainnet-only. Calls on testnet will return an error.
Write operations require an unlocked wallet (use
```
bun run wallet/wallet.ts unlock
```
first).
Always run
```
quote-buy
```
or
```
quote-sell
```
before trading to verify costs and set slippage bounds.
Market IDs are epoch millisecond timestamps (e.g.,
```
1771853629839
```
), not MongoDB
```
_id
```
.

The

get-market

subcommand takes MongoDB

_id

(e.g.,

699c573ea7bb5ad25fee68a0

), not

marketId

Write operations MUST use
```
PostConditionMode.Allow
```
— the contract moves STX internally (sender → pool → fee wallets) and default post-conditions block this.
```
isActive
```
can be
```
true
```
even after
```
endDate
```
passes — the contract owner must manually resolve. Always check
```
isResolved
```
and compare time.
Winning shares pay 1 STX each on redemption; losing shares pay nothing. Burns all shares.
Gas fees are approximately 0.05–0.1 STX per transaction, in addition to the share cost.
LMSR pricing: cost of shares follows a logarithmic curve — buying more shares in one direction increases price. Get a fresh quote immediately before submitting a buy.
