Yes, Gate.io does offer an API feature. To use it, you need to generate an API key from your account settings. You can create up to 20 API keys per account, with customizable permissions (such as spot trading, wallet access, and withdrawals). The API allows you to integrate various features for automation, including querying currencies, executing trades, and managing withdrawals.
If you're setting up an API, you can also attach an IP whitelist for added security. Each key can be configured to be read-only or read-write depending on your needs.
