v0.1.6 — March 13, 2026

Breaking changes

Place Order — `POST /v1/pm/events/{eventId}/markets/{marketId}/orders`

This is a breaking change. All existing integrations must be updated.

Request body changes

Change	Before	After
Outcome field	`outcome` (`YES` / `NO`)	`outcomeId` (UUID of the outcome)
Order type	Implicit (market order if no `price`)	`type` field required (`LIMIT` or `MARKET`)

New optional fields (CLOB markets)

Field	Type	Description
`timeInForce`	`string`	`GTC`, `GTD`, `FAK`, or `FOK`. Defaults to `GTC` for limit orders, `FAK` for market orders.
`postOnly`	`boolean`	If `true`, the order is rejected instead of crossing the spread. Limit orders only.
`maxSlippage`	`number`	Maximum acceptable slippage for market orders (0.00–1.00).
`expiresAt`	`string`	ISO 8601 expiration timestamp. Required for `GTD` orders.

Migration guide

Before:

{
  "side": "BUY",
  "outcome": "YES",
  "amount": 100,
  "currency": "USD",
  "price": 0.70
}

After:

{
  "side": "BUY",
  "outcomeId": "c3d4e5f6-a7b8-9012-cdef-345678901234",
  "amount": 100,
  "type": "LIMIT",
  "currency": "USD",
  "price": 0.70,
  "timeInForce": "GTC"
}

To get the outcomeId, use the Get Event endpoint — each outcome in a market has an id field.

Get Quote — `POST /v1/pm/events/{eventId}/markets/{marketId}/quote`

Request body changes

Change	Before	After
Outcome field	`outcome` (`YES` / `NO`)	`outcomeId` (UUID of the outcome)

Migration guide

Before:

{
  "side": "BUY",
  "outcome": "YES",
  "amount": 100,
  "currency": "USD"
}

After:

{
  "side": "BUY",
  "outcomeId": "c3d4e5f6-a7b8-9012-cdef-345678901234",
  "amount": 100,
  "currency": "USD"
}

Response format changes

The Place Order response now uses a unified order key instead of separate ammOrder / clobOrder keys: Before:

{
  "engine": "CLOB",
  "clobOrder": { ... }
}

After:

{
  "engine": "CLOB",
  "order": { ... }
}

The engine field (AMM or CLOB) remains unchanged.
