required

Position direction: long or short.

Available options:
long,
short
collateralUsdc
required

Collateral (margin) in USDC, human units — e.g. 100 = 100 USDC. Position size = collateral × leverage.

leverage
required

Target fill leverage for each slice.

maxLeverage
required

Upper leverage bound for slice fills.

runTimeSeconds
integer
required

Execution window in seconds; the order is filled in slices spread across this duration.

Required range: x > 0

integer

Pair index (alternative to pair).

Required range: x >= 0
pair
string

Pair symbol, e.g. ETH/USD (separators /, -, _ accepted; case-insensitive).

Minimum string length: 1
nonce

Replay-protection nonce (uint256; unordered Permit2-style bitmap, not sequential). A random one is generated when omitted — only pass a value to pre-reserve or deterministically retry an intent. Check availability via GET /v2/nonce.

deadlineMs

Intent expiry as a unix timestamp in MILLISECONDS (not seconds). Defaults to now + the service value shown in /v2/meta → defaults.intentDeadlineMs.

Fixed exposure target in base-asset units; omit for pure-collateral TWAPs.
