Hold your horses: introducing rate limiting to ESI
Hi all, Today we're announcing the introduction of rate limiting to ESI. This is a significant change that will help ensure fair usage across all applications. Rate limiting will be implemented using a floating window system, and we'll be rolling it out gradually across different routes. The first route that will be rate limited is /status,...
Route to the future: upgrading the /route route
Today we're announcing a major upgrade to the /route route in ESI. We've completely rewritten it from Python to Go, changed it from GET to POST, and significantly improved its performance and reliability.
Reworking the SDE: a fresh start for static data
Today we're announcing a complete rework of how we build and distribute the Static Data Export (SDE).
Early access: Corporation Projects
Today we're announcing an early access period for new Corporation Projects routes in ESI. This early access will run for two weeks and be limited to developers in the EVE Partner Program. Feedback from this group will help us validate the design and make adjustments before going public.
Changing pagination: turning a new page
Today we're announcing changes to how ESI deals with pagination. This new system will be used for the first time with the introduction of Corporation Projects later this summer. We'll also be opening a discussion thread on Discord for Q&A and feedback from third-party developers.
Changing specs: from Swagger to OpenAPI
Today we're announcing changes to how we serve our API specifications. We'll also be opening a discussion thread on Discord for Q&A and feedback from third-party developers. Moving forward, we will be publishing our specs as OpenAPI 3.0 and 3.1, and no longer as Swagger 2.0. New updates will be made in the OpenAPI specs only, while we keep Swagger specs in a read-only mode around for a while. We are also introducing a new UI to view the specs.
Changing versions: /v42/ was getting out of hand
Today we're announcing changes to the ESI endpoint versioning strategy. Moving forward, new routes will no longer rely on versions embedded in their URL paths. Instead, we are introducing an X-Compatibility-Date header that works for the entirety of the API. Existing routes also adopt this new behavior, but we will continue supporting the versioned URLs for the foreseeable future.
