Deprecated: Wyvern order posting to Shared Storefront contract

What: we are discontinuing support for Wyvern order posting to the OpenSea shared storefront contract on Monday, July 25th. This means that we will no longer accept any Wyvern programatic order submissions, and you will receive an error if you attempt to hit the endpoint.

Programmatic orders now restored

We’ve completed our investigation into performance issues that were impacting our API and SDK and have now restored access to programmatic orders through our API and SDK.

SDK v4.0.0-beta available for Seaport testing

We’ve released v4.0.0-beta of our SDK which introduces support for fetching and posting of offers and listings on the new Seaport contract. Developers can begin to test against this beta version on Rinkeby.

Extended downtime on programmatic orders

We are investigating performance issues that are impacting our API and SDK. On May 20, we disabled programmatic orders to allow us to investigate and work towards a resolution. We expect programmatic orders through our API and SDK will be back up in the next week, as soon as we resolve the performance issues.

Testnets API no longer requires an API key

What: Starting today, we are no longer requiring an API key to make requests to our Testnets API endpoints.

Stream API Beta is now available

We’ve launching a beta version the Stream API, a new websocket-based service that enables developers to receive events as they occur across our marketplace.

Added event_timestamp to /events endpoint responses

What: We're going to be making a small addition to the response on our /events endpoint to add event_timestamp, which will be a more accurate representation of when the event took place.

Side parameter now required on /wyvern/v1/orders

What: We’re now requiring that the side parameter must be included in all requests to the /wyvern/v1/orders endpoint, as was previously announced. This parameter is used to filter the response to either buy or sell orders and requests will now fail if they don’t include this parameter.

Requiring side parameter on /wyvern/v1/orders

What: As of April 26, we will require the side parameter to be included in all requests to the /wyvern/v1/orders endpoint. This parameter is used to filter the response to either buy or sell orders and was previously optional. Moving forward, requests will fail if they don’t include this parameter.

Delaying removal of orders from assets endpoints

What: We’re delaying the removal of orders from our /assets and /asset/:contract_address/:token_id endpoints, which we had previously communicated would take place on March 21. Developers will be able to continue issuing requests with the optional include_orders flag set to true in order to fetch orders using these endpoints. We will provide an updated plan and date for this migration in the coming weeks.
