Out-of-game EVE data access is provided by CCP through the [[EVE Swagger Interface]] (ESI). However, this access method is not convenient for casual use. Fortunately, third-party services have arisen to provide better access for the casual player. EVE Market data can be accessed through an API provided by [https://api.evemarketer.com/ec/ EVEMarketer]. This service replaces a previous service provided by the defunct EVE Central. EVEMarketer API access methods are very similar to those used by EVE Central but different enough that previous calls will not work. These API calls can be used in a spreadsheet (e.g., Google Sheets, Excel) to provide programmatic access to Market Data even for casual users.
