Finviz offers a fantastic screener application, but it lacks exposed APIs and is server-rendered. Therefore, I developed a server to fetch pages from Finviz and parse them to extract relevant information. I hope this can assist you in your financial research.

1. Simply run the main.go file. By default, it will listen on port 8000.
2. Use Docker to run the image docker run -p 8000:8000 ppaanngggg/finviz-proxy.
3. Utilize my RapidAPI service, Finviz Screener.

1. PORT (default: 8000) - the listening port.
2. TIMEOUT (default: 60s) - this is the http client timeout.
3. THROTTLE (default: 100) - this represents the maximum number of concurrent requests.
4. CACHETTL (default: 60s) - this is the table cache timeout.

1. ELITELOGIN (default: false) - determines if Elite Account login is enabled.
2. EMAIL (default: ) - email of your Elite Account.
3. PASSWORD (default: ) - password of your Elite Account.

This endpoint provides all the necessary parameters to make requests to the Finviz screener.

Request:

No parameters required.

# curl example
curl localhost:8000/params

Response:

1. sorters - determines the sorting method for results.
2. signals - a special filter defined by Finviz for signals.
3. filters - all available filters of the Finviz screener.

// output sample of `/params`

		{
			"id": "fs_exch",
			"name": "Exchange",
			"description": "Stock Exchange at which a stock is listed.",
			"options": [

	],
	"signals": [

		...
	]
}

This endpoint returns a structured table with the screener results based on the provided parameters.

You can use any value from the API response of /params to manage your /table response.
