Starting today, you will no longer be able to create new listings for or make new offers on BNB Smart Chain (BSC) NFTs.

We no longer return NFTs that are hidden from an account's profile page on our retrieve NFTs by account endpoint. NFTs are hidden by our systems automatically, or by users manually on their account page.

OpenSea API will no longer support API requests with non-versioned paths. Starting August 24th, all API requests must use one of the v1/ or v2/ prefixes to make API calls.

We are excited to announce the addition of a new field in the OpenSea API - the encoded_token_ids field. It is present in the responses of our collection and trait offer read endpoints in the criteria object - the new field is a concise and efficient way to represent a list of token ids that pertain to a given collection / trait offer. When decoded using the provided SDK function, developers can now see a list of all tokens that could be used to fulfill the offer.

On June 27th, 2023, we released 4 new endpoints under our /v2 schema:

Today, OpenSea has launched 2 new events in the Stream API. The new events will be emitted when orders, both listings and offers, have been invalidate or revalidated. Emitting these events will allow marketplace aggregators and other consumers who are maintaining a copy of the OpenSea order book to more easily ensure the orders are executable.
