Foreign (public) node API

This API is used to query node about various information on the blockchain. Foreign (public) API is designed to be used also by users other than owner. If your Foreign API is public, others can use it to get blockchain information.

This API is used by wallets to interact with the blockchain, validate and send transactions.

By default, node API is exposed only for local connections and requires authentication.

When running epic node with defaults, foreign API URL is available at localhost:3413/v2/foreign.

Basic Authentication credentials:

user: epic,
password saved in ~/.epic/main/.api_secret file.

In order to change API URL, authentication and other settings go to (by default) ~/.epic/main/epic-server.toml file.

Make sure your epic node is running before calling API endpoints.

API call must be done via POST requests with JSON payload.

Examples

How to send POST request via cURL

Windows PowerShellUnix Terminal

With authentication

curl -u "epic:$(cat ~/.epic/main/.api_secret)" -d '{\"jsonrpc\": \"2.0\", \"method\": \"get_version\", \"params\": [], \"id\": 1}' -H "Content-Type: application/json" http://localhost:3413/v2/foreign

Without authentication

curl -d '{\"jsonrpc\": \"2.0\", \"method\": \"get_version\", \"params\": [], \"id\": 1}' -H "Content-Type: application/json" http://localhost:3413/v2/foreign

With authentication

curl -u "epic:$(cat ~/.epic/main/.api_secret)" -d '{"jsonrpc": "2.0", "method": "get_version", "params": [], "id": 1}' -H "Content-Type: application/json" http://localhost:3413/v2/foreign

Without authentication

curl -d '{"jsonrpc": "2.0", "method": "get_version", "params": [], "id": 1}' -H "Content-Type: application/json" http://localhost:3413/v2/foreign

Example API call:

PythonNodeJS

pip install requests

Python 3.5+

from typing import Union

    url = f"{api_url}/{api_type}"
    auth = (api_user, api_secret)

    try:

foreign_call = api_call(method='get_version', params=[], api_type='foreign')

npm install request

NodeJS 18.0+

const request = require('request');

const owner_payload = {

// Foreign API Call
