REST API

API for Warthog node version v0.10.3 "dd054a2"

Configuration

API is accessed via the RPC endpoints of the node. The endpoints socket can be configured via the --rpc command line option:

JSON RPC endpoint options:
  -r, --rpc=IP:PORT          JSON RPC endpoint  (default=`127.0.0.1:3000')

For example invoke

$./wart-node --rpc=0.0.0.0:3000

to start the node with RPC listening on all devices on port 3000.

Warning

The RPC endpoint should not exposed to the internet, use appropriate firewall settings.

Below we assume the RPC socket is accessible at localhost:3000. On startup the node reports the RPC endpoint setting:

[info] RPC endpoint is 127.0.0.1:3000.

Show balance of an account for a specific asset. The :account parameter is the account address, and :token is the token spec (e.g., asset:0e4825efffa294610d2ac376713e3bcc9b53d378e823834b64e5df01f75d3b0c).

Balance Types

The API returns three balance types:

Type	Description
`total`	The total balance of the account
`locked`	Balance locked in open orders
`mempool`	Balance currently used by pending transactions in the mempool

Spendable amount is total - locked and can be reused for new transactions. If total - locked is sufficient but total - locked - mempool is not, the system may evict lower-fee transactions from the mempool to make room for a higher-fee transaction.
