     EMS - REST API
  
     This section will provide necessary information about the `CoinAPI EMS REST API` protocol. This API is also available in the Postman application: <a href=\"https://postman.coinapi.io/\" target=\"_blank\">https://postman.coinapi.io/</a>        Implemented Standards:    * [HTTP1.0](https://datatracker.ietf.org/doc/html/rfc1945)   * [HTTP1.1](https://datatracker.ietf.org/doc/html/rfc2616)   * [HTTP2.0](https://datatracker.ietf.org/doc/html/rfc7540)     ### Endpoints  <table>   <thead>     <tr>       <th>Deployment method</th>       <th>Environment</th>       <th>Url</th>     </tr>   </thead>   <tbody>     <tr>       <td>Managed Cloud</td>       <td>Production</td>       <td>Use <a href=\"#ems-docs-sh\">Managed Cloud REST API /v1/locations</a> to get specific endpoints to each server site where your deployments span</td>     </tr>     <tr>       <td>Self Hosted</td>       <td>Production</td>       <td>IP Address of the <code>ems-gateway</code> container/excecutable in the closest server site to the caller location</td>     </tr>   </tbody> </table>  ### Authentication If the software is deployed as `Self-Hosted` then API do not require authentication as inside your infrastructure, your company is responsible for the security and access controls.  If the software is deployed in our `Managed Cloud`, there are 2 methods for authenticating with us, you only need to use one:   1. Custom authorization header named `X-CoinAPI-Key` with the API Key  2. Query string parameter named `apikey` with the API Key  3. <a href=\"#certificate\">TLS Client Certificate</a> from the `Managed Cloud REST API` (/v1/certificate/pem endpoint) while establishing a TLS session with us.  #### Custom authorization header You can authorize by providing additional custom header named `X-CoinAPI-Key` and API key as its value. Assuming that your API key is `73034021-THIS-IS-SAMPLE-KEY`, then the authorization header you should send to us will look like: `X-CoinAPI-Key: 73034021-THIS-IS-SAMPLE-KEY` <aside class=\"success\">This method is recommended by us and you should use it in production environments.</aside> #### Query string authorization parameter You can authorize by providing an additional parameter named `apikey` with a value equal to your API key in the query string of your HTTP request. Assuming that your API key is `73034021-THIS-IS-SAMPLE-KEY` and that you want to request all balances, then your query string should look like this: `GET /v1/balances?apikey=73034021-THIS-IS-SAMPLE-KEY` <aside class=\"notice\">Query string method may be more practical for development activities.</aside>
