# REST API Usage ## Configuration Enable the rest API by adding the api_server section to your configuration and setting `api_server.enabled` to `true`. Sample configuration: ``` json "api_server": { "enabled": true, "listen_ip_address": "127.0.0.1", "listen_port": 8080, "verbosity": "info", "jwt_secret_key": "somethingrandom", "CORS_origins": [], "username": "Freqtrader", "password": "SuperSecret1!" }, ``` !!! Danger "Security warning" By default, the configuration listens on localhost only (so it's not reachable from other systems). We strongly recommend to not expose this API to the internet and choose a strong, unique password, since others will potentially be able to control your bot. !!! Danger "Password selection" Please make sure to select a very strong, unique password to protect your bot from unauthorized access. You can then access the API by going to `http://127.0.0.1:8080/api/v1/ping` in a browser to check if the API is running correctly. This should return the response: ``` output {"status":"pong"} ``` All other endpoints return sensitive info and require authentication and are therefore not available through a web browser. To generate a secure password, either use a password manager, or use the below code snipped. ``` python import secrets secrets.token_hex() ``` !!! Hint Use the same method to also generate a JWT secret key (`jwt_secret_key`). ### Configuration with docker If you run your bot using docker, you'll need to have the bot listen to incoming connections. The security is then handled by docker. ``` json "api_server": { "enabled": true, "listen_ip_address": "0.0.0.0", "listen_port": 8080 }, ``` Add the following to your docker command: ``` bash -p 127.0.0.1:8080:8080 ``` A complete sample-command may then look as follows: ```bash docker run -d \ --name freqtrade \ -v ~/.freqtrade/config.json:/freqtrade/config.json \ -v ~/.freqtrade/user_data/:/freqtrade/user_data \ -v ~/.freqtrade/tradesv3.sqlite:/freqtrade/tradesv3.sqlite \ -p 127.0.0.1:8080:8080 \ freqtrade trade --db-url sqlite:///tradesv3.sqlite --strategy MyAwesomeStrategy ``` !!! Danger "Security warning" By using `-p 8080:8080` the API is available to everyone connecting to the server under the correct port, so others may be able to control your bot. ## Consuming the API You can consume the API by using the script `scripts/rest_client.py`. The client script only requires the `requests` module, so Freqtrade does not need to be installed on the system. ``` bash python3 scripts/rest_client.py [optional parameters] ``` By default, the script assumes `127.0.0.1` (localhost) and port `8080` to be used, however you can specify a configuration file to override this behaviour. ### Minimalistic client config ``` json { "api_server": { "enabled": true, "listen_ip_address": "0.0.0.0", "listen_port": 8080 } } ``` ``` bash python3 scripts/rest_client.py --config rest_config.json [optional parameters] ``` ## Available endpoints | Command | Description | |----------|-------------| | `ping` | Simple command testing the API Readiness - requires no authentication. | `start` | Starts the trader | `stop` | Stops the trader | `stopbuy` | Stops the trader from opening new trades. Gracefully closes open trades according to their rules. | `reload_config` | Reloads the configuration file | `trades` | List last trades. | `delete_trade ` | Remove trade from the database.

Tries to close open orders. Requires manual handling of this asset on the exchange. :param trade_id: Deletes the trade with this ID from the database. edge Return information about edge. forcebuy Buy an asset. :param pair: Pair to buy (ETH/BTC) :param price: Optional - price to buy forcesell Force-sell a trade. :param tradeid: Id of the trade (can be received via status command) logs Show latest logs. :param limit: Limits log messages to the last logs. No limit to get all the trades. performance Return the performance of the different coins. profit Return the profit summary. reload_config Reload configuration. show_config Returns part of the configuration, relevant for trading operations. start Start the bot if it's in the stopped state. status Get the status of open trades. stop Stop the bot. Use `start` to restart. stopbuy Stop buying (but handle sells gracefully). Use `reload_config` to reset. trades Return trades history. :param limit: Limits trades to the X last trades. No limit to get all the trades. version Return the version of the bot. whitelist Show the current whitelist. ``` ## Advanced API usage using JWT tokens !!! Note The below should be done in an application (a Freqtrade REST API client, which fetches info via API), and is not intended to be used on a regular basis. Freqtrade's REST API also offers JWT (JSON Web Tokens). You can login using the following command, and subsequently use the resulting access_token. ``` bash > curl -X POST --user Freqtrader http://localhost:8080/api/v1/token/login {"access_token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpYXQiOjE1ODkxMTk2ODEsIm5iZiI6MTU4OTExOTY4MSwianRpIjoiMmEwYmY0NWUtMjhmOS00YTUzLTlmNzItMmM5ZWVlYThkNzc2IiwiZXhwIjoxNTg5MTIwNTgxLCJpZGVudGl0eSI6eyJ1IjoiRnJlcXRyYWRlciJ9LCJmcmVzaCI6ZmFsc2UsInR5cGUiOiJhY2Nlc3MifQ.qt6MAXYIa-l556OM7arBvYJ0SDI9J8bIk3_glDujF5g","refresh_token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpYXQiOjE1ODkxMTk2ODEsIm5iZiI6MTU4OTExOTY4MSwianRpIjoiZWQ1ZWI3YjAtYjMwMy00YzAyLTg2N2MtNWViMjIxNWQ2YTMxIiwiZXhwIjoxNTkxNzExNjgxLCJpZGVudGl0eSI6eyJ1IjoiRnJlcXRyYWRlciJ9LCJ0eXBlIjoicmVmcmVzaCJ9.d1AT_jYICyTAjD0fiQAr52rkRqtxCjUGEMwlNuuzgNQ"} > access_token="eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpYXQiOjE1ODkxMTk2ODEsIm5iZiI6MTU4OTExOTY4MSwianRpIjoiMmEwYmY0NWUtMjhmOS00YTUzLTlmNzItMmM5ZWVlYThkNzc2IiwiZXhwIjoxNTg5MTIwNTgxLCJpZGVudGl0eSI6eyJ1IjoiRnJlcXRyYWRlciJ9LCJmcmVzaCI6ZmFsc2UsInR5cGUiOiJhY2Nlc3MifQ.qt6MAXYIa-l556OM7arBvYJ0SDI9J8bIk3_glDujF5g" # Use access_token for authentication > curl -X GET --header "Authorization: Bearer ${access_token}" http://localhost:8080/api/v1/count ``` Since the access token has a short timeout (15 min) - the `token/refresh` request should be used periodically to get a fresh access token: ``` bash > curl -X POST --header "Authorization: Bearer ${refresh_token}"http://localhost:8080/api/v1/token/refresh {"access_token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpYXQiOjE1ODkxMTk5NzQsIm5iZiI6MTU4OTExOTk3NCwianRpIjoiMDBjNTlhMWUtMjBmYS00ZTk0LTliZjAtNWQwNTg2MTdiZDIyIiwiZXhwIjoxNTg5MTIwODc0LCJpZGVudGl0eSI6eyJ1IjoiRnJlcXRyYWRlciJ9LCJmcmVzaCI6ZmFsc2UsInR5cGUiOiJhY2Nlc3MifQ.1seHlII3WprjjclY6DpRhen0rqdF4j6jbvxIhUFaSbs"} ``` ## CORS All web-based frontends are subject to [CORS](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS) - Cross-Origin Resource Sharing. Since most of the requests to the Freqtrade API must be authenticated, a proper CORS policy is key to avoid security problems. Also, the standard disallows `*` CORS policies for requests with credentials, so this setting must be set appropriately. Users can configure this themselves via the `CORS_origins` configuration setting. It consists of a list of allowed sites that are allowed to consume resources from the bot's API. Assuming your application is deployed as `https://frequi.freqtrade.io/home/` - this would mean that the following configuration becomes necessary: ```jsonc { //... "jwt_secret_key": "somethingrandom", "CORS_origins": ["https://frequi.freqtrade.io"], //... } ``` !!! Note We strongly recommend to also set `jwt_secret_key` to something random and known only to yourself to avoid unauthorized access to your bot.
