A request for quote (RFQ) is how we get a price for a parlay. A parlay is one bet on two or more outcomes, called legs, that must all win. When a user asks for a parlay, we send an RFQ to every registered liquidity provider (LP). We pick the best quote and ask its LP to confirm before the trade executes. This section is for LPs who want to receive RFQs and answer them with prices. RFQs are opt-in. Registering doesn’t change your order-book trading on /nbx/v2.
We send RFQs only for parlays of two or more legs. Eligibility lists which legs can combine.

​
How a round works

Your pricer is the service that answers RFQs for your LP account.
1

A user asks for a parlay

The user sends a list of outcomeIds. We check the legs, create an rfq_id, and store the RFQ.
2

We send the RFQ to every pricer

Each registered pricer gets the RFQ over the transport it chose. The auction stays open for 3 seconds.
3

You answer with a price

Return a price and a max_wager, the largest stake you’ll take. You can also decline.
4

We pick the winner

The lowest price wins, because it pays the user the most. A tie goes to the larger max_wager.
5

The winner confirms

When the user accepts, we ask you to confirm the actual wager at your price. You have 1 second to answer, called the last look.
6

The parlay settles

The parlay settles as one position when its legs grade. Settlement explains the payout.
We drop an answer in these cases:
  • It’s malformed.
  • Its max_wager is zero or less.
  • It arrives after the 3-second auction closes.
We also pass over a quote in these cases:
  • Its max_wager is below the user’s min_wager, or below $10, whichever is higher.
  • Your LP account’s cash balance can’t cover your collateral for the full max_wager.
Your collateral is the money you put up against the user’s stake. We ask for the confirm over the transport that carried your quote. If you confirm in time, the trade executes. If you reject or miss the last look, it doesn’t.

​
Choose a transport

You can price over a WebSocket, over webhooks, or over both. Both use the same 3-second auction and 1-second last look. Pick the WebSocket if you can’t expose a public endpoint. Pick webhooks if you already run a service. If you use both, each RFQ arrives on both. We keep your first quote in a round and ignore any later one. We then confirm on the transport that carried that quote.

​
Webhook endpoints

For webhooks, you run three POST endpoints under one base URL. We add /quote, /confirm, and /ping to the base URL you register. The base can include a path, like https://pricer.example.com/novig. Each request carries an X-Novig-Signature header. Webhook signing shows how to check it.

​
Get started

Every pricer registers first, with POST /rfq/pricer. Registration is self-serve.
  • Register with a webhookUrl to get webhooks. The response holds your shared secret.
  • Register without a webhookUrl to use only the WebSocket.
  • Test your webhook with POST /rfq/pricer/ping before live traffic arrives.
Registration walks through each call.
