Parlay Market Requests

This WebSocket API will be deprecated on July 1, 2026. See the Migration Guide to move to the Centrifuge-based API.

When a bettor requests a Parlay Market, a message is sent via the markets:parlay channel. In order to offer orders on Parlay Markets, you will need to subscribe to this channel. The payload will contain the marketHash that is associated with the Parlay Market. You can post orders to this market as you would for any other market, using this marketHash. The payload also contains the token and size that the bettor is requesting. The legs in the payload contain the underlying legs that make up the parlay market. You can query for market data on each leg’s marketHash to determine current orders for that individual market. ParlayMarket PAYLOAD FORMAT

Name	Type	Description
marketHash	string	The parlay market associated with this request
requestorId	string	An anonymized stable ID for the bettor who requested the parlay market
baseToken	string	The token this request is denominated in
requestSize	number	The size in baseTokens that the bettor is requesting. See the token section of how to convert this into nominal amounts
legs	ParlayMarketLeg[]	An array of legs that make up the parlay

ParlayMarketLeg PAYLOAD FORMAT

Name	Type	Description
marketHash	string	The market for an individual leg within the parlay
bettingOutcomeOne	boolean	The side the bettor is betting for an individual leg within the parlay

Note that the requestSize is only indicating what the user is requesting, but does not limit market makers in how much they want to offer. You are allowed to offer any size.

const channel = realtime.channels.get('markets:parlay');
channel.subscribe((message) => {
  console.log(message.data);
});

The above command returns JSON structured like this:

  "marketHash": "0x38cceead7bda65c18574a34994ebd8af154725d08aa735dcbf26247a7dcc67bd",
