REST API & FreqUI

FreqUI

Freqtrade provides a builtin webserver, which can serve FreqUI, the freqtrade UI.

By default, the UI is not included in the installation (except for docker images), and must be installed explicitly with freqtrade install-ui. This same command can also be used to update freqUI, should there be a new release.

Once the bot is started in trade / dry-run mode (with freqtrade trade) - the UI will be available under the configured port below (usually http://127.0.0.1:8080).

!!! info "Alpha release" FreqUI is still considered an alpha release - if you encounter bugs or inconsistencies please open a FreqUI issue.

!!! Note "developers" Developers should not use this method, but instead use the method described in the freqUI repository to get the source-code of freqUI.

Configuration

Enable the rest API by adding the api_server section to your configuration and setting api_server.enabled to true.

Sample configuration:

    "api_server": {
        "enabled": true,
        "listen_ip_address": "127.0.0.1",
        "listen_port": 8080,
        "verbosity": "error",
        "enable_openapi": false,
        "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.

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:

{"status":"pong"}

All other endpoints return sensitive info and require authentication and are therefore not available through a web browser.

Security

To generate a secure password, best use a password manager, or use the below code.

import secrets
secrets.token_hex()

!!! Hint "JWT token" Use the same method to also generate a JWT secret key (jwt_secret_key).

!!! Danger "Password selection" Please make sure to select a very strong, unique password to protect your bot from unauthorized access. Also change jwt_secret_key to something random (no need to remember this, but it'll be used to encrypt your session, so it better be something unique!).

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.

    "api_server": {
        "enabled": true,
        "listen_ip_address": "0.0.0.0",
        "listen_port": 8080
    },

Uncomment the following from your docker-compose file:

    ports:
      - "127.0.0.1:8080:8080"

!!! Danger "Security warning" By using 8080:8080 in the docker port mapping, the API will be available to everyone connecting to the server under the correct port, so others may be able to control your bot.

Rest API

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.

python3 scripts/rest_client.py <command> [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

{
    "api_server": {
        "enabled": true,
        "listen_ip_address": "0.0.0.0",
        "listen_port": 8080
    }
}

python3 scripts/rest_client.py --config rest_config.json <command> [optional parameters]

OpenAPI interface

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.

> 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:

> curl -X POST --header "Authorization: Bearer ${refresh_token}"http://localhost:8080/api/v1/token/refresh
{"access_token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpYXQiOjE1ODkxMTk5NzQsIm5iZiI6MTU4OTExOTk3NCwianRpIjoiMDBjNTlhMWUtMjBmYS00ZTk0LTliZjAtNWQwNTg2MTdiZDIyIiwiZXhwIjoxNTg5MTIwODc0LCJpZGVudGl0eSI6eyJ1IjoiRnJlcXRyYWRlciJ9LCJmcmVzaCI6ZmFsc2UsInR5cGUiOiJhY2Nlc3MifQ.1seHlII3WprjjclY6DpRhen0rqdF4j6jbvxIhUFaSbs"}

CORS

All web-based front-ends are subject to 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:

{
    //...
    "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.
