Hello,
I tested this above code with certain modifications, it works fine. Now how and where to get Gold Price API on daily basis to be used in php code or as json format.

thanks

Hi, look at www.goldapi.io. That is a Gold & Silver Prices Live & Historical REST JSON API. LBMA and COMEX are data sources. Please give a try. Full Disclosure: I'm a developer and ready to answer any questions regarding this API.

I have gone through ample of API's and they weren't free anyhow so I implemented it as a data scrapper. For daily rates you can schedule a Cron job (lets say every midnight) to trigger this script and store its results in DB and query from it.

Can you show some code or any refrence!?

Any one share currency exchange Json format or API link...

Does it get the rates as 15 minutes late?

How can I get this kind of graph for gold price for a specific city, country

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

http://goldprice.org/NewCharts/gold/images/goldsilverpricesforcalculators.txt link is dead

do we have new link ?

The website is now using the following link(s) to fetch the rates:

• https://data-asg.goldprice.org/dbXRates/USD
• https://data-asg.goldprice.org/GetData/USD-XAG/1

To test out the API, substitute it with different values.

thanks.
do you have any others links to get prices?

How to get the values in g (grams), i need to get the gold price in India.

@anburocky3
you can calculate it if you have price of ounce
search in google about the math
its easy.
((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?
