EVE Stable Infrastructure

EVE Swagger Interface (ESI) is an API that can be used by third party applications to interact with data from the EVE game servers. It replaces CREST and the XML API which were shut down on May 8th, 2018. The data returned by ESI is in the JSON format.

ESI has both public-data and authenticated endpoints, the latter of which require a character to log in via EVE SSO to their character account to gain access to information specific to their character or, provided they have the appropriate corporate roles, their corporation. As of March 2025 there are 76 public-data and 119 Authenticated endpoints (195 total).

CCP has indicated that their goal is to completely replace the Static Data Export (SDE) with ESI, but as of September 2023, there are still many missing features. For example, industry recipes still require the SDE.

As a reminder to developers, it is expressly forbidden for developers of third party applications to use them for ill intent

ESI and SSO are commonly used together, however they do have independent features and uses as well. For this reason, they have been split into their own articles. See EVE SSO for information regarding the character authentication (and management thereof) aspect. Besides EVE SSO, the Static Data Export and Image Server might also be useful.

ESI Endpoints

ESI provides 195 endpoints, 76 of which related to public data and need no character or client authentication, and 119 of which are authenticated as they relate to privileged information about specific characters or corporations.

The general categories these endpoints fall under are:

Category	Public	Auth	Description
Alliances	4		General information about Alliances and their member corporations
Assets		6	Inventory details for characters and corporations
Calendar		4	Read and respond to a character's calendar events
Character	4	10	Information relating specifically to a character, where it does not fall under any other category.
Clones		2	Information on a character's clones and their active implants
Contacts		9	Read Contacts lists for characters, corporations and alliances, and edit them for characters.
Contracts	3	6	List public, character and corporate contracts, bids placed on them, and items contained in them.
Corporation	4	18	Information relating specifically to a corporation, where it does not fall under any other category.
Dogma	5		Information regarding Dogma, EVE's system for attributes on items and entities.
Faction Warfare	6	2	Public statistics on faction warfare, systems, leaderboards, and a character's statistics.
Fittings		3	View, create or delete a character's in-game saved fittings.
Fleets		14	Provides endpoints for a complete breakdown of a fleet's composition, and allows managing it externally.
Incursions	1		A list of currently active Incursions and some basic info about them
Industry	2	6	System Cost Indices, Industry facilities, and all information about a character's active industry jobs.
Insurance	1		A list of insurance prices for all classes of ships.
Killmails	1	2	Retrieve killmails relating to a character, or all details on a killmail for which you have the appropriate information.
Location		3	View whether a character is online, what they're flying, and where they are located.
Loyalty	1	1	List offers available from a provided NPC Corporation's LP Store, and a character's available LP.
Mail		9	All actions related to viewing, sending and deleting in-game mail for a character.
Market	6	5	Market orders and histories, as well as a character or corporation's specific orders.
Planetary Industry	1	3	Details on a character's planetary colonies and their layouts, as well as public information on PI Schematics.
Routes	1		Use the game's algorithms to calculate a route between two systems
Search		1	Perform a search on the provided string against the chosen categories. If for a character, will also search private things the character can see.
Skills		3	Information on a character's attributes, skills and skill training queue.
Sovereignty	3		Lists of sovereignty campaigns, systems and structures.
Status	1		Status of the game: Whether it's running, what version, and how many players are logged in.
Universe	29	1	Just about all general public, static data in the game.
User Interface		5	Allows opening certain UI windows for a character if they are logged in to the game.
Wallet		6	Character and Corporation wallet balances and transactions.
Wars	3		Details on all wars that have happened in the game, including their killmails.

Examples

To get a list of all alliances in EVE, the /v2/alliances endpoint can be used. It lists the alliance ID of all alliances. Since it is a public endpoint, it is even possible to a look at it in the browser, although the data comes is in machine-readable JSON: https://esi.evetech.net/latest/alliances/

Some endpoints also support parameter in the URL. For example the type endpoint /v3/universe/types/{type_id}/ returns information about a type ID. The rifter has type ID 587. To look up informations like its description, the {type_id} part in the URL is replaced with the type ID. The full URL would then be https://esi.evetech.net/latest/universe/types/587/

If possible, CCP requests that users add a descriptive user agent to any ESI request, including a contact email, so that they can be contacted instead of being banned for e.g. causing too much load on the ESI servers.

Tips & Tricks

Most ESI endpoints don't have rate-limits, but are error-limited instead, meaning an ESI application is blocked if it makes too many erroneous requests. However, there are two notable exceptions: The /v2/characters/{character_id}/corporationhistory/ and the /v1/markets/{region_id}/history/ endpoints have rate limits of 300 requests per IP per minute. This rate limit is unfortunately not documented in the ESI docs.

Eve uses a lot of 'ID's, that are unique for things. Ships, players, corporations, systems all have unique IDs. Most IDs are arranged in 'Ranges' as well. Comparing IDs against these ranges to find out what type of ID it is. https://developers.eveonline.com/docs/guides/id-ranges/ has these ranges listed out. Figuring out what an ID is can answer many questions of what ESI to find out what it is. There are two very fast ways to find Names for IDs as well. Linking a thing in chat, then hit enter, then right click, and copy. This will put the URL code in the clipboard. Alternately, go to a site like https://zkillboard.com/ and the ID will be at the end. Ex: https://zkillboard.com/ship/22460 the Eris id is 22460.
