Endpoints

GET /ping

Returns pong

GET /info

Returns a JSON payload describing the state of the queues for each network. For example:

{
    "3": {
        "ether": {
            "full": false,
            "size": 4
        },
        "zrx": {
            "full": false,
            "size": 6
        }
    },
    "42": {
        "ether": {
            "full": false,
            "size": 8
        },
        "zrx": {
            "full": false,
            "size": 20
        }
    }
}

GET /ether/:recipient?networkId=:networkId

Schedules a transaction that sends 0.1 ETH to the recipient on the network specified by networkId where recipient is a hex encoded Ethereum address prefixed with 0x. If no networkId is provided via query parameters the faucet will default to network 42 (Kovan).

GET /zrx/:recipient?networkId=:networkId

Schedules a transaction that sends 0.1 ZRX to the recipient on the network specified by networkId where recipient is a hex encoded Ethereum address prefixed with 0x. If no networkId is provided via query parameters the faucet will default to network 42 (Kovan).

GET /order/weth/:recipient?networkId=:networkId

Returns a JSON payload describing an order for 0.1 WETH in exchange for 0.1 ZRX signed by the dispenser address on the network specified by networkId. The taker is specified by recipient where recipient is a hex encoded Ethereum address prefixed with 0x. If no networkId is provided via query parameters the faucet will default to network 42 (Kovan).

GET /order/zrx/:recipient?networkId=:networkId

Returns a JSON payload describing an order for 0.1 ZRX in exchange for 0.1 WETH signed by the dispenser address on the network specified by networkId. The taker is specified by recipient where recipient is a hex encoded Ethereum address prefixed with 0x. If no networkId is provided via query parameters the faucet will default to network 42 (Kovan).

Example request

curl -i http://localhost:3000/ether/0x14e2F1F157E7DD4057D02817436D628A37120FD1\?networkId=3

This command will request the local server to initiate a transfer of 0.1 ETH from the dispensing address to 0x14e2F1F157E7DD4057D02817436D628A37120FD1 on the Ropsten testnet.
