Struct OpenOrder 

pub struct OpenOrder {

    pub id: String,
    pub status: String,
    pub owner: String,
    pub maker_address: String,
    pub market: String,
    pub asset_id: String,
    pub side: String,
    pub original_size: String,
    pub size_matched: String,
    pub price: String,
    pub outcome: String,
    pub expiration: String,
    pub order_type: String,
    pub associate_trades: Vec<String>,
    pub created_at: i64,
}

A resting order, as returned by GET /data/orders and GET /data/order/{orderID} (both return this same shape).

This is an order summary, not a signed order: the venue does not echo back the signed payload, so there is no token_id, maker_amount, signature_type, metadata, builder, salt, or signature here. Field names are snake_case on the wire — there is deliberately no rename_all.

Pinned to a body captured from the live venue on 2026-07-24 (see open_order_deserializes_captured_response below), cross-checked against the /data/orders response schema in docs/specs/clob/openapi.yaml. Prior to 0.22.0 this struct declared camelCase names, a flattened [SignedOrder], and a string created_at, so any response containing a real order failed to deserialize with missing field `assetId` .

Fields the schema marks required are non-optional here, matching the capture. If the venue ever omits one, deserialization fails loudly rather than silently producing a half-empty order — and ListOrders::send_raw is the escape hatch for reading the body anyway.

Fields

id: String

Order ID (0x-prefixed hash).

status: String

Order status, e.g. LIVE.

owner: String

Owning API key (a UUID, not an address).

maker_address: String

Maker address — the proxy/deposit wallet, not the signing EOA.

market: String

Market condition ID.

asset_id: String

Asset (token) ID for the outcome being traded.

side: String

BUY or SELL.

original_size: String

Original order size, as a decimal string.

size_matched: String

Size matched so far, as a decimal string.

price: String

Limit price, as a decimal string.

outcome: String

Outcome label, e.g. Yes.

expiration: String

Expiration as a Unix timestamp string; "0" means no expiry.

order_type: String

Order type, e.g. GTC.

associate_trades: Vec<String>

IDs of trades associated with this order.

created_at: i64

Creation time as a Unix timestamp in seconds — an integer on the wire, not a string.
