Retrieve all offers

This endpoint is used to get all open offers for a given collection. It returns: all offers on individual NFTs, all collection offers, and all trait offers. The offers are sorted by ascending date (oldest listings first) -- at this time, we do not support any other sorting methods.

The response has two fields: offers and an optional next cursor in case the number of offers is greater than our default page size (100). This endpoint returns only a subset of the fields found in our orders endpoint. Here is the model for each offer:

order_hash
chain
criteria: specifies if the offer was for an individual NFT, a collection offer, or a trait offer
protocol_data
