Return balance from a provided block

eth_get_balance

Mimics Ethereum JSON RPC's eth_getBalance

Example:

https://fonscan.io/api
   ?module=account
   &action=eth_get_balance
   &address={addressHash}

Request params

Parameter	Description
address	string containing the address hash.
block	optional. Block number as a string, or latest, earliest or pending Latest is the latest balance in a consensus block. Earliest is the first recorded balance for the address. Pending is the latest balance in a consensus or nonconsensus block.

Example Result

{
  "id": 1,
  "jsonrpc": "2.0",
  "result": "0x0234c8a3397aab58"
}

Get the native token balance for an address

balance

Many chains use their own native tokens. On Ethereum, this will return the result in "Ether", on Gnosis it will be "xDai", etc. Results are returned in wei.

Example:

https://fonscan.io/api
   ?module=account
   &action=balance
   &address={addressHash}

Request params

Parameter	Description
address	string containing the address hash.

Example Result

{
  "message": "OK",
  "result": "663046792267785498951364",
  "status": "1"
}

Also available through a GraphQL address query.

If the balance hasn't been updated recently, the node is double-checked to fetch the absolute latest balance. This will not be reflected in the current request, but once it is updated, subsequent requests will show the updated balance. If you want to know if there is a check for another balance, use the balancemulti action. That contains a property called stale that will let you know to recheck that balance in the near future.

Get balance for multiple addresses

balancemulti

Example:

https://fonscan.io/api
   ?module=account
   &action=balancemulti
   &address={addressHash1,addressHash2,addressHash3}

Request params

Parameter	Description
address	string containing the address hash, comma separated. Max 20 addresses.

Example Result

{
  "message": "OK",
  "result": [
    {
      "account": "0xddbd2b932c763ba5b1b7ae3b362eac3e8d40121a",

      "stale": false
    }
  ],
  "status": "1"
}

Also available through a GraphQL 'addresses' query

If the balance hasn't been updated in a long time, the node is double checked to fetch the absolute latest balance. This is not reflected in the current request, but once it is updated, subsequent requests will show the updated balance. The stale attribute will be set to true if a new balance is being fetched.
