While testing the SDK, I noticed that the getNFTsByOwner method doesn't work for certain NFTs, I will guess it's because the NFT isn't indexed yet? Not sure!

Working example:

Bscscan link

await provider.getNFTsByOwner({
  blockchain: "bsc",
  walletAddress: "0xe1b852bbec7ab161d554765667814cb3ca0ad142",
  pageSize: 2,
  pageToken: "",
  filter: [
      {
          "0xC3c3B849ED5164Fb626c4a4F78e0675907B2C94E": []
      }
  ]
});

Not working example:

Bscscan link

await provider.getNFTsByOwner({
  blockchain: "bsc",
  walletAddress: "0xe1b852bbec7ab161d554765667814cb3ca0ad142",
  pageSize: 2,
  pageToken: "",
  filter: [
      {
          "0x21Dc6714c4a3fccD67f53453b46e1c892A54C8E7": []
      }
  ]
});

My problem I used "@ankr.com/[email protected]" package for get account balance with my premium plan, tried to call ankr_getAccountBalance 10 times, 5 times I got empty returned result

This is my request params

Current result: 5 times got this empty result / total 10 tried requests

Expected With the same request above the method should return data instead of empty result in the randomly time

This PR adds a new type Blockchain and assigns it to the blockchain fields in all API responses for better autocomplete support.

(PS: I work at Ankr too xD, DevRel)

I tried to use this example from the docs but got tokenPrice = 0 for ETH curl --location --request POST 'https://rpc.ankr.com/multichain' \ --header 'Content-Type: application/json' \ --data-raw '{ "jsonrpc": "2.0", "method": "ankr_getAccountBalance", "params": { "blockchain": "eth", "walletAddress": "0xfa9019df60d3c710d7d583b2d69e18d412257617" }, "id": 1 }'

Current result for ETH tokenPrice

Hi @romanankr! Here is the PR with some suggestions for the readme. I tried to make the language we use in our readme more dev-friendly and tried to make it easier for people to get started with our package.

The metadata information obtained through getNFTsByOwner does not match what is in opensea.

The json below is the NFT information obtained through ankr.

ANKR owner: 0xc8B1735929eDa28822721fd9Bdbb1D3de2b3eab2

I'm trying to read a price history from polygon and I just get an error, I doesn't matter with contract address I pass. Tried already by sdk and api directly. Tried with the other blockchains and is working, expect polygon.

Example:

    "jsonrpc": "2.0",
    "method": "ankr_getTokenPriceHistory",
    "params": {  
        "blockchain": "polygon",
        "contractAddress": "0x0000000000000000000000000000000000001010",
        "toTimestamp": 1667195581,
        "interval": 6000,
        "limit": 8
    },
    "id": 1
}

Result:
{
    "jsonrpc": "2.0",
    "id": 137,
    "error": {
        "code": -32005,
        "message": "Not found: no prices for token=0x0000000000000000000000000000000000001010"
    }
}

Get account balance by running this

curl --location --request POST 'https://rpc.ankr.com/multichain' \
--header 'Content-Type: application/json' \
--header 'X-API-KEY: $$$$$$$$$$$$$$$$$$$$$$' \
--data-raw '{
    "jsonrpc": "2.0",
    "method": "ankr_getAccountBalance",
    "params": {  
        "walletAddress": "0xdaf835f11537fca6db91e91c266d153200f46d52",
        "pageSize": 10000
    },
    "id": 1
}'

This is list tokens of 0xdaf835f11537fca6db91e91c266d153200f46d52

Expected result ETH token returned in the result

Current result Missed ETH token in the result
