OPENAPI-SPOT-REST

1. API Overview

The MGBX trading platform API provides programmatic trading capabilities, allowing developers to create orders, query market data, and other functions via HTTP requests.

2. Service Address

API Base URL: https://open.mgbx.com

3. Authentication Mechanism

3.1 Authentication Parameters

Request Header	Description
X-Access-Key	Your API access key
X-Signature	Signature generated using your secret key against request parameters
X-Request-Timestamp	Request timestamp (milliseconds)
X-Request-Nonce	Random string to prevent replay attacks

3.2 Signature Algorithm

Signature algorithm process:

Sort regular request parameters alphabetically by key name (using TreeMap)
Build parameter string: key1=value1&key2=value2&...
Append timestamp at the end of parameter string: key1=value1&key2=value2&...&timestamp=xxx (where timestamp value is the same as the X-Request-Timestamp header)
Use HMAC-SHA256 algorithm with secretKey as the key to sign the final parameter string, encoding using UTF-8
Convert the signature result to a hexadecimal string
Send parameter content in the form of application/x-www-form-urlencoded query string

3.3 Public Endpoints

The following endpoints are public and do not require any authentication. They can be accessed directly:

Batch Order Creation Notes:

Supports submitting orders for different trading pairs in a single request.
Batch operations follow a "best-effort" principle—failure of some orders will not affect the processing of others.
The response only includes the count of successful and failed orders. To obtain the status of specific orders, use the Order Query API.
The API supports a maximum of 20 orders per request. Exceeding this limit will return an error.

Batch Order Cancellation Notes:

The batch cancellation API supports cancelling up to 20 orders per request. Requests exceeding this limit will return an error.
Batch cancellation is processed asynchronously. A successful response only indicates that the request has been accepted.
Some orders may not be canceled due to reasons such as already being filled or previously canceled. This does not affect the cancellation of other orders.
It is recommended to confirm the final status of all orders through the Order Query API after cancellation.
In high-frequency trading scenarios, it is advisable to space out cancellation requests appropriately to avoid excessive calls.
