Available on: Polymarket, Opinion, Limitless. Other venues raise NotSupported in hosted mode — for those, run a local PMXT service.
Use any EVM private key. Your USDC sits in a non-custodial PreFundedEscrow on Polygon — the single funding location for every hosted venue (including Opinion, which PMXT settles cross-chain for you). PMXT cannot move funds without your EIP-712 signature.

Unified order id. Stable across the order's lifetime; reuse it in fetchOrderHosted and cancelOrderHosted.

​
status
string
required

Lifecycle status. Open-order values include resting and partial; submit responses pass through the upstream status string (failed when an error was raised); cancel responses return the venue's cancel-acknowledgement status.

​

Order direction. null on cancel responses, which only carry id and status.

Available options:
buy,
sell
​
type
enum<string> | null

Order type echoed from the build. null on cancel responses.

Available options:
market,
limit
​
amount
number | null

Order size in outcome shares. For market submits, this is the shares actually obtained (tokens_bought / tokens_sold); for resting limit orders it is the total shares originally requested. null on cancel responses.

​
price
number | null

Limit price in probability units [0, 1] for limit orders. null for market orders and cancel responses.

​
filled
number

Shares filled so far. For market submits this equals the shares obtained on-chain; for resting limit orders it is the running fill total.

​

Chain the order settled on. Always polygon for hosted orders today (Opinion settles cross-chain via the same Polygon escrow). null on cancel responses.

​
block_number
integer | null

Polygon block height at which the order settled. null until settlement.
