IP Limit Notice:
The BYW API lottery data collection interface allows a maximum of 3 IP addresses to access each lottery by default. Under normal circumstances, if the server's public IP address remains unchanged, a maximum of 3 servers can be used for data collection per day. If you receive a message indicating that the number of access IPs has exceeded the maximum limit, you can log in to User Center - My API Keys - IP Whitelist to purchase additional IP slots or clear existing accessed IPs.
Request Limit Notice:
The default request frequency for a single API interface is 1 request per second. If more than 1 request is made within 1 second, a "Request frequency too high" message will be displayed, which may cause data collection to fail. For the same account and the same API interface, each IP is limited to a maximum request frequency of 1 request per second for each lottery. Multiple IPs can collect data simultaneously without triggering any conflicting rate limits.
IPv4/IPv6 Access Information:
If your server or client supports both IPv4 and IPv6, it may prefer to use an IPv6 address when accessing the API. If the IPv6 network connection is unstable, experiences connection timeouts, or the server's public IP address changes frequently, this may result in API access errors, data collection failures, or frequent triggering of IP access restrictions.
If you experience unstable IPv4/IPv6 connectivity, IPv6 connection timeouts, frequent changes to your server's public IP address, or other related issues, we recommend using a stable IPv4 network to access the API and adjusting your server or client network configuration as needed. For detailed instructions on configuring IPv4 as the preferred protocol, please refer to: How to Make Windows, Linux, and macOS Prefer IPv4 for API Access.
Privacy & Security Notice:
IP access records for the API are temporarily encrypted and stored in the application's memory cache. These records are not permanently stored. They are only used to verify access permissions for the current day. To protect user privacy and security, these records are automatically cleared the following day.
