INTRODUCTION

Welcome

Welcome to ETHGas API reference! Our WebSocket and REST APIs provide seamless access to market data, order placement, and more.

We offer REST API call examples in HTTP requests and Python language. You can view the code examples in the panel to the right, and toggle between programming languages with the tabs in upper right corner.

ETHGas APIs can be used in different languages via community supported packages:

Python (python-ethgas)

Please contact us via email or on our Telegram channel if you've any questions or suggestions. We'd love to hear from you!

Endpoints are divided into two categories: /api/v1/p and /api/v1.

/api/v1/p endpoints provide access to market data, order book snapshots, trade history, and more; information that is available to all users. These endpoints are open and do not require authentication, allowing developers to retrieve real-time market data for analysis or display purposes. On the other hand, /api/v1 endpoints require authentication and provide access to account-specific information and trading functionality.

For interacting with our /api/v1 endpoints, a login is required. The login workflow is as follows:

Get the login sign message by calling the endpoint /api/v1/user/login with the appropriate addr.
Sign the login message and call the endpoint /api/v1/user/login/verify with the addr, nonceHash, and signature. You will now receive the JWT access token, as well as user-related data, and now be able to call any private endpoints.
Before the access token has expired, call /api/v1/user/login/refresh to get a new access token.

private session: The JWT access token is valid for 1 hour, after each hour an access token refresh is required. A private REST request needs to include the JWT access token in the request's HEADER, format: Authorization: 'Bearer accessToken'. A private session is valid for 7 days, after 7 days a re-login is required. A private websocket session needs to include the access token in the session header, format: 'Bearer accessToken'

Example python code showing this workflow is on the right under the python tab.

REST API

Response structure

Every API response contains a success flag and a response body.

Name	Type	Description
success	boolean	Whether API call is successful or not
data	object	Response body

Authentication

Code sample:

curl -X POST /api/v1/user/login?addr=0x8F02425B5f3c522b7EF8EA124162645F0397c478&name=username

import requests

url = "https://mainnet.app.ethgas.com/api/v1/user/login"

payload = {
    'addr': '0x5eF1B2c02f5E39C0fF667611C5d7EfFb0E7df305',
    'name': 'username'    
}

headers = {
  'Content-Type': 'application/json'
}

response = requests.post(url, headers=headers, params=payload)

print(response.text)

Example response:

{
    "success": true,
    "data": {
        "status": "verify",
        "eip712Message": "{\"types\":{\"EIP712Domain\":[{\"name\":\"name\",\"type\":\"string\"},{\"name\":\"version\",\"type\":\"string\"},{\"name\":\"chainId\",\"type\":\"uint256\"},{\"name\":\"verifyingContract\",\"type\":\"address\"}],\"data\":[{\"name\":\"hash\",\"type\":\"string\"},{\"name\":\"message\",\"type\":\"string\"},{\"name\":\"domain\",\"type\":\"string\"}]},\"primaryType\":\"data\",\"message\":{\"hash\":\"52a90c73\",\"message\":\"Please sign this message to verify account ownership\",\"domain\":\"ethgas.com\"},\"domain\":{\"name\":\"ETHGas Login\",\"version\":\"1\",\"chainId\":32382,\"verifyingContract\":\"0x0000000000000000000000000000000000000000\"}}",
        "nonceHash": "52a90c73"
    }
}

Request

Parameter	Required	Type	Description
addr	YES	string	User's EOA account (account) address
name	NO	string	Display name

Response Body

Name	Type	Description
status	string	Login status
eip712Message	object	EIP712 message
nonceHash	string	A unique four-byte nonce to identify this particular login request

Usage

Get the response from /api/v1/user/login and sign the eip712Message and send the signed message through /api/v1/user/login/verify

Code sample:

curl -X POST /api/v1/user/login/verify?addr=0xe61f536f031f77C854b21652aB0F4fBe7CF3196F&nonceHash=517d9272&signature=0xc046037ec795f4cfe7aca33a0c283c0152bae91008b3e14b84be50f91f0e2db714054dee85b840e3edf0e26480231a684447f48337de64ea6697a3552aa9351a1b
