MEXC, a leading cryptocurrency exchange, offers an API trading service that allows users to automate their trading strategies and execute trades programmatically. While this service provides numerous benefits, it also comes with certain restrictions that users must be aware of to ensure compliance and optimal use. In this article, we will explore the various restrictions associated with MEXC's API trading.

API Key Permissions

MEXC's API trading system uses API keys to authenticate and authorize access to the platform's trading functionalities. Users can set different permission levels for their API keys, which include read-only, trading, and withdrawal permissions. However, there are restrictions on how these permissions can be configured.

• Read-only permissions allow users to retrieve account information and market data but do not permit executing trades or withdrawing funds.
• Trading permissions enable users to place orders, cancel orders, and manage their trading activities, but they do not allow for withdrawals.
• Withdrawal permissions are the most sensitive and are typically restricted to prevent unauthorized access to funds. Users must exercise caution when enabling these permissions.

It is important to note that MEXC imposes a strict policy on withdrawal permissions. Only one API key can have withdrawal permissions enabled at any given time. This restriction is in place to enhance security and prevent potential misuse of funds.

Rate Limits

To ensure fair usage and prevent abuse of the API, MEXC imposes rate limits on the number of requests that can be made within a specific time frame. These rate limits vary depending on the type of endpoint being accessed.

• Public endpoints, such as market data retrieval, typically have higher rate limits compared to private endpoints that involve account-specific actions.
• Private endpoints, which include actions like placing orders or retrieving account balances, have lower rate limits to protect user data and prevent excessive API usage.

Exceeding these rate limits can result in temporary or permanent suspension of API access. Users must monitor their API usage and implement appropriate rate-limiting mechanisms in their applications to avoid hitting these limits.

Order Restrictions

MEXC's API trading system also imposes certain restrictions on the types and sizes of orders that can be placed through the API.

• Minimum Order Size: Each trading pair on MEXC has a minimum order size that must be met for the order to be accepted. Users must ensure their orders meet these minimum requirements to avoid rejection.
• Maximum Order Size: Similarly, there are maximum order sizes for each trading pair. Exceeding these limits can result in the order being rejected or partially filled.
• Order Types: MEXC supports various order types, including market orders, limit orders, and stop orders. However, not all order types are available for all trading pairs. Users must check the supported order types for their chosen trading pair before placing an order.

Additionally, MEXC may impose restrictions on the number of open orders a user can have at any given time. This is to prevent order book manipulation and ensure a fair trading environment.

Security Measures

To protect users and their funds, MEXC implements several security measures that affect API trading.

• IP Whitelisting: Users can configure IP whitelisting for their API keys, which restricts API access to specific IP addresses. This adds an extra layer of security but can limit the flexibility of where the API can be accessed from.
• Two-Factor Authentication (2FA): MEXC requires 2FA for certain actions, including enabling withdrawal permissions on API keys. Users must have 2FA enabled to access these sensitive functionalities.
• API Key Expiration: MEXC allows users to set expiration dates for their API keys. Once an API key expires, it can no longer be used, and a new key must be generated. This feature helps mitigate the risk of long-term unauthorized access.

Trading Pair Restrictions

Not all trading pairs on MEXC are available for API trading. Some pairs may be restricted due to regulatory requirements or other factors. Users must check the list of available trading pairs before attempting to trade via the API.

• Margin Trading: MEXC offers margin trading for certain pairs, but not all of these pairs are available for API trading. Users must verify which margin pairs support API trading.
• Futures Trading: Similarly, futures trading is available on MEXC, but the availability of futures pairs for API trading may be limited. Users should confirm the supported futures pairs before using the API for futures trading.

Compliance and Regulatory Restrictions

MEXC operates in a highly regulated environment, and as such, it must adhere to various compliance and regulatory requirements. These requirements can impact the functionality of the API trading service.

• KYC Requirements: MEXC requires users to complete Know Your Customer (KYC) verification to access certain features, including API trading with higher limits. Users must comply with these KYC requirements to fully utilize the API.
• Geographical Restrictions: Certain countries or regions may be subject to restrictions due to local regulations. Users from these areas may have limited access to API trading functionalities.
• Anti-Money Laundering (AML) Policies: MEXC's AML policies may impose restrictions on the amount of funds that can be traded or withdrawn via the API. Users must adhere to these policies to prevent account suspension or closure.
