What parameters needed to query by CURL or HTTPie ?

[coolbq]

Hi, I'm trying to build query strings to do download history data from investing.com. I want to query by CURL or HTTPie. But it returns error this way. Does investing.com need any special parameters in the query?
I also test it in the Postman, but returns the same error. The query string is like this one "https://www.investing.com/instruments/HistoricalDataAjax?curr_id=1114321&smlID=27721383&header=MRNA Historical Data&st_date=02/01/2021&end_date=04/27/2021&interval_sec=Daily&sort_col=date&sort_ord=DESC&action=historical_data"

Do I miss anything? Or it is not possible to query by CURL or HTTPie ?

Hi @coolbq, AFAIK you can cURL it, but you need to specify not just the parameters, but also the headers and so on, for a quick reference, check this piece of code from investpy and try to replicate it using cURL. If it works let us know how you did it! 👍🏻

investpy/investpy/stocks.py

Lines 273 to 295 in 26a61ca

	header = symbol + ' Historical Data'
	params = {
	"curr_id": id_,
	"smlID": str(randint(1000000, 99999999)),
	"header": header,
	"interval_sec": interval.capitalize(),
	"sort_col": "date",
	"sort_ord": "DESC",
	"action": "historical_data"
	}
	head = {
	"User-Agent": random_user_agent(),
	"X-Requested-With": "XMLHttpRequest",
	"Accept": "text/html",
	"Accept-Encoding": "gzip, deflate",
	"Connection": "keep-alive",
	}
	url = "https://www.investing.com/instruments/HistoricalDataAjax"
	req = requests.post(url, headers=head, data=params)

For your concrete example, the header value should be "MRNA Historical Data", as MRNA is the symbol.
