[Ethereum] Is it possible to get the token transfers of a address

etherscan

I want to get token transfers of an address (incoming) but i guess once i have this sorted i can figure that out.

So for example here – https://etherscan.io/address/0x3f5ce5fbfe3e9af3971dd833d26ba9b5c936f0be#tokentxns

They have all the token transfers and i can't really see in their API to get all the token transfers so i was wondering if anyone knew how to do to get all token transfers going on the address.
I have tried doing many stuff while trying to using web3.js and try subscribe to events.
I realise when a smart contract transfers a token the Transfer event is called and emitted but i don't see how to show all the token transfers using etherscan API.
Thanks guys.

If you wish to use etherscan API, you can use https://etherscan.io/apis#logs.

However, you'll have to know contract addresses of all tokens that you wish to watch.

The Transfer event for ERC20 is defined as

event Transfer(address indexed _from, address indexed _to, uint256 _value);

That means:

topic0 will be the hash of the signature of the event itself
topic1 will be the address of the sender
topic2 will be the address of the receiver

For orientation, you can look into the logs in the transaction receipt of a transfer transaction. -> e.g. https://etherscan.io/tx/0x5c354e4f25f2da8ee608c445cad43c171bc553859dd787fc0800a904344a7ecd#eventlog

Tokens – Obtain Token Transfer Data from an Address

How about using Etherscan's Event Log API?

https://api.etherscan.io/api?module=logs&action=getLogs
    &fromBlock=0
    &toBlock=latest
    &address=[Token Contract Address]
    &topic0=0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef
    &topic1=[From Address, padded to 32 bytes - optional]
    &topic2=[To Address, padded to 32 bytes - optional]

In the above topic0 is the signature of an ERC20 Transfer event.

For example, the following link shows you all the send transactions of LLL tokens from my account (two transactions).

Here, your X (the token) is represented by the token's contract address, which is easy enough to find out for the various tokens.

As always, the API will return you a maximum of 10000 results, so you may need to manage fromBlock and toBlock accordingly.

[Ethereum] Etherscan API – Get all token balances

As previously mentioned it doesn't appear possible using etherscan. But it's possible using the (free) ethexplorer.io API.

The format is:

http://api.ethplorer.io/getAddressInfo/[YOUR_ADDRESS]?apiKey=freekey

For example:

http://api.ethplorer.io/getAddressInfo/0x32Be343B94f860124dC4fEe278FDCBD38C102D88?apiKey=freekey

API documentation is here:
