# Market Maker

Any market maker willing to register with Dfyn Exchange RFQ module, needs to expose an endpoint that has the following structure:

### Get Quote

## Get a quote from the market maker for the base token

<mark style="color:blue;">`GET`</mark> `https://api.marketmaker.com/v1/getQuote`

This endpoint should return a calldata that includes the quote price and the signature. As a market maker, you need to call Dfyn's RFQ contract to fetch the nonce. Nonce has to be included in the signed data.

**Note:** The deadline should be in ***seconds**.*
