Get Quotes

When using GET quotes, orders are returned based on the params details provided. quotes endpoint is ideal for determining which order(s) will satisfy a specific order size and side. The returned quotes are ordered by price, and only the order(s) that satisfy the size (cumulatively) will be returned.

Additionally, it is possible to receive RFQ quotes along with public quotes by specifying a taker address. The allows users to find the best possible public/private quote combination for a particular quote size.
