The website is now using the following link(s) to fetch the rates:
To test out the API, substitute it with different values.
thanks.
do you have any others links to get prices?

@anburocky3

((price / ounce) * rank gold) / 24
@anburocky3 you can calculate it if you have price of ounce search in google about the math its easy. ((price / ounce) * rank gold) / 24
can you explain with example
@anburocky3 you can calculate it if you have price of ounce search in google about the math its easy. ((price / ounce) * rank gold) / 24
can you explain with example
if the ounce price now is 2500 usd
and in india you buy or sell gold rank 24
===> how many grams is the ounce => ounce = 31.1034768 grams
((price / ounce how many grams) * rank gold) / 24
((2500/31.1034768)*24)/24
=80.3$
the price of one grams of gold 24k => 80.3$
change only the rank gold & price
((price / ounce how many grams) * rank gold) / 24
((2500/31.1034768)*24)/24
((2500/31.1034768)*22)/24
((2500/31.1034768)*21)/24

@surferxo3 cool thx! there are no rate limits or anything on these free apis?
@surferxo3 I think we have to get price_update_token to use on URL.
In inner source of page I see:
var price_update_token = "e103de5a616e4";
WILL THE ABOVE SHARED CODE FETCH GOLD PRICE FOR ALL CURRENCIES FOR DIFFERENT UNITS AND MEASUREMENT, LIKE 10GM GOLD PRICE IN INDIA, 20 gm gold price in Dubai, etc or it will fetch only in one currency, unit for a specific country. Please answer my query
Have you found any solution?
do we have new link ?
