# Get an OpenSea collection's order book

`GET /opensea/collection/{slug}/depth`

Returns the full bid/ask ladder for a collection: resting listings and offers grouped into price levels with the quantity available at each. This is the depth chart behind OpenSea's own collection page, and it is the fastest way to see how thin or deep the book is above the floor.
