This API returns JSON and is open to any EchoMTG user interested in writing custom scripts, apps, or integrations. The api system is uses EchoMTG identifiers (emid), a unique numeric ID given to every item in the EchoMTG database. Multiverse IDs were not used because Judge Foils and other promo cards do not have multiverseids. Two community API wrappers are available: PHP Wrapper by Andrew Gioia and JAVA Wrapper for Android. If you have any suggestions or questions please join the discord channel and look for Teeg.
Attain a token by Registering an Echo user. When logged in your API token appear in these docs. API Tokens expire after 24 hours. New tokens are attained by Authenticating. If your application integration for Echo users needs permanent tokens, join discord and ask for Teeg.
