edge-rest-wallet

A REST API for storing & sending money, powered by Edge

This repository implements a simple API for accessing a wallet on a web server. This can be useful for automated payouts, promotions, e-commerce, and various similar things.

We make this code available for free, but it does require an Edge SDK API key. We recommend closing external ports for security to prevent outside access and should only be used on your local server. Please copy config.sample.json to config.json and add your API key in there.

API Docs

Get a balance for a wallet

# Make sure to add the right type of cryptocurrency wallet plugins to your config.json file so you can access the type (Ex: "plugins": {"bitcoin": true})
$.get('http://localhost:$PORT/balances/?type=$TYPE')
  .then(function(d) {console.log(d)})

# balances example
await fetch('http://localhost:8008/balances/?type=bitcoin', { method: 'GET' })


# balances result
>    {"BTC": "1100"}

Get a list of transactions for a wallet

$.get('http://localhost:$PORT/transactions/?type=$TYPE')
  .then(function(d) {console.log(d)})

# transactions example
await fetch('http://localhost:8008/transactions/?type=bitcoin', { method: 'GET' })

# transactions result
>  [{
>    [{"blockHeight":619132,
>    "date":1582751709.749,
>    "ourReceiveAddresses": [
            "3JVeTHattdtGBAzWskiLzjeuojTb4Rjuui"
        ]

>    "nativeAmount":"1100",
>    "networkFee":"0",
>    "currencyCode":"BTC"}]
>  }]

Send cryptocurrency from a wallet to a public address

# nativeAmount is in satoshi so this will need to be multiplied by 100,000,000, see example for reference

$.post('http://localhost:$PORT/spend/?type=$TYPE', ({ spendTargets: [{ nativeAmount, publicAddress }])

# spend .000011 bitcoin to address 3JVeTHattdtGBAzWskiLzjeuojTb4Rjuui
await fetch('http://localhost:8008/spend/?type=bitcoin', {
  body: JSON.stringify({ spendTargets: [{ "1100", "3JVeTHattdtGBAzWskiLzjeuojTb4Rjuui" }] }),
  headers: {
    'Content-Type': 'application/json'
  },
  method: 'POST'
  })
