*The public RPC endpoints are not intended for production applications. Please use dedicated/private RPC servers when you launch your application, drop NFTs, etc. The public services are subject to abuse and rate limits may change without prior notice. Likewise, high-traffic websites may be blocked without prior notice.

Common HTTP Error Codes- 403 -- Your IP address or website has been blocked. It is time to run your own RPC server(s) or find a private service.
- 429 -- Your IP address is exceeding the rate limits. Slow down! Use the Retry-After HTTP response header to determine how long to wait before making another request.
