+# binance-rest-api-proxy
+
+A service which proxies any Binance REST API calls to make them originate from a region you like.
+Default configuration creates AWS Lambda function and URL in eu-west-3 (Paris) region. This can be changed in the package.json.
+
+## Usage
+
+* You need AWS CLI installed and configured (search AWS Docs to do it).
+* You need AWS `sam` CLI tool (search AWS Docs to do it).
+* You will probably need Docker Desktop installed.
+
+1. `npm install`
+2. `npm run deploy`
+
+If everything is deployed you will get the service URL in the terminal.
+Now, using this URL you can make any requests to Binance REST API, by replacing `https://api.binance.com/api/v3/` with this URL in requests:
+* `https://api.binance.com/api/v3/ticker/price` -> `<ServiceURL>/ticker/price`
+
+It supports all Binance REST API requests that do not include HTML body.
+It supports the `x-mbx-apikey` HTTP header.
+
+If you fill like this project helped you, you can support me on Patreon:
