Moralis General
#5

thanks. looking forward to it

#6

Update:
the https://docs.moralis.io/moralis-server/deep-index-api
seems to not exist anymore.
I am still trying to get token price from BSC and i get this error:
{ā€œmessageā€:ā€œAPI KEY missing from x-api-key headerā€}
would appreciate any help.
I need to post prices from BSC on my website.
Thank you.

Hi,
Try to go to https://admin.moralis.io/web3Api and there try a simple API from that list.

#8

thatā€™s what i did and it came up with this link:
https://deep-index.moralis.io/api/v2/erc20/0x8e428aA75b271EbF905DB7e3F2970453E976481e/price?chain=bsc

Also, i donā€™t know what ProviderUrl means.

I used the /erc20/{address}/price
Choose BSC chain

#9

You can ignore provider url for now.
I get this output:

{
  "nativePrice": {
    "value": "12738528727",
    "decimals": 18,
    "name": "Binance Coin",
    "symbol": "BNB"
  },
  "usdPrice": 0.00000474682112594,
  "exchangeAddress": "0xcA143Ce32Fe78f1f7019d7d551a6402fC5350c73",
  "exchangeName": "PancakeSwap v2"
}
#10

i get this:
{ā€œmessageā€:ā€œAPI KEY missing from x-api-key headerā€}

Also, the token name is not Binance coin ā€¦ but thatā€™s less important. Im mostly interested in the price.

Ok, try to refresh the page few times, it looks like it is a problem with generating the API key for your account. If the problem still persists, weā€™ll need to take a look at your account.

#12

refreshed it like 5 times. Maybe i didnā€™t set something right?
I have to mention that iā€™m a noob so, donā€™t expect any system problems. Most probably itā€™s my fault.

#13

What you see for the curl command?
I see something like this:

curl -X 'GET' \
  'https://deep-index.moralis.io/api/v2/erc20/0x8e428aA75b271EbF905DB7e3F2970453E976481e/price?chain=bsc' \
  -H 'accept: application/json' \
  -H 'X-API-Key: MY_API_KEY_HERE'
#14 
curl -X 'GET' \
  'https://deep-index.moralis.io/api/v2/erc20/0x8e428aa75b271ebf905db7e3f2970453e976481e/price?chain=bsc' \
  -H 'accept: application/json' \
  -H 'X-API-Key: <here is an apy key>
Should i post the api key also?
#15

Also, i get this response in my moralis account:

{
  "nativePrice": {
    "value": "12651542928",
    "decimals": 18,
    "name": "Binance Coin",
    "symbol": "BNB"
  },
  "usdPrice": 0.00000475001883575,
  "exchangeAddress": "0xcA143Ce32Fe78f1f7019d7d551a6402fC5350c73",
  "exchangeName": "PancakeSwap v2"
}

But when i access the link in another browser tab,
https://deep-index.moralis.io/api/v2/erc20/0x8e428aa75b271ebf905db7e3f2970453e976481e/price?chain=bsc
i get this:
{ā€œmessageā€:ā€œAPI KEY missing from x-api-key headerā€}

#16

Ok, got it now, you can not use only that link to get the data, you also have to send the API key in the header request.

#17

yes, i tested the curl here https://reqbin.com/req/c-vdhoummp/curl-get-json-example
and realized iā€™m way too noob for this. Thank you for your patience. Iā€™ll try to integrate it in my website.

Hey there, I am having a similar issue - I can get a good response in some apps, but not all. Hereā€™s what it looks like in Xcode:

XcodeResponse

Any ideas? Thanks.

I donā€™t know how did you set that http header there. You can find here an example on how you should set that header value in curl: https://admin.moralis.io/web3Api after you try there a function.

#20

this is how i used mine

//cURL price data from JSON				
$url = "https://deep-index.moralis.io/api/v2/erc20/" . $contract . "/price?chain=" . $network . "";

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

$headers = array(
   "accept: application/json",
   "X-API-Key: <your api key here>",
);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);

$resp = curl_exec($curl);
curl_close($curl);
	

$yummy = json_decode($resp);
$usdprice = @$yummy->usdPrice;
//end cURL price data from JSON

iā€™m getting data from 2 chains. by contract.
also, gettin g data for each crypto in real time will make your site unbearable slow.
What i did was to set up a cron-job to run once an hour and populate database with the data for each crypto then pull data from data base with 1h term.

Yeah, sorry - I wasnā€™t able to upload more than one picture at a time. Hereā€™s what the full request looks like in Swift:

XcodeCall
XcodeCall876Ɨ880 88.2 KB

func getHeldNFTs(walletAddress:String) {
        // Prepare URL
        let url = URL(string: "\(moralis.baseEndpoint)\(walletAddress)/nft?chain=\(chain)&format=decimal")
        var request = URLRequest(url: url!)
        // Set Request Headers
        request.setValue(moralis.apiKey, forHTTPHeaderField: "X-API-Key")
        // Perform Request
        URLSession.shared.dataTask(with: request) {(data, response, error) in

            if let responseData = try? JSONDecoder().decode(GetAllNFTResponse.self, from: data!) {
                let total = responseData.total
                print("\(total)")
            }
        }
        .resume()
    }

The original curl request (which works fine anywhere else) is:

curl -v \
	-X GET \
	-H "User-Agent: HTTPBot-iOS/2021.1" \
	-H "X-API-Key: MY-API-KEY" \
	"https://deep-index.moralis.io/api/v2/MY-WALLET-ADDRESS/nft?chain=mumbai&format=decimal"
#22

Iā€™m wondering if itā€™s an issue with how Swift or Xcode requests the data. The POST requests work great; I can get data and pass it to an app without an issue. This simple one, thoughā€¦

#23

can you print somehow the url that you get here to check if it is the expected one?

#24

hi there,
Where can I get MY-API-KEY?
Looking forward to any idea from anyone.
