Solana Cluster RPC Endpoints

Solana maintains dedicated api nodes to fulfill JSON-RPC requests for each public cluster, and third parties may as well. Here are the public RPC endpoints currently available and recommended for each public cluster:

Devnet

  • https://api.devnet.solana.com - single Solana-hosted api node; rate-limited

Rate Limits

  • Maximum number of requests per 10 seconds per IP: 100
  • Maximum number of requests per 10 seconds per IP for a single RPC: 40
  • Maximum concurrent connections per IP: 40
  • Maximum connection rate per 10 seconds per IP: 40
  • Maximum amount of data per 30 second: 100 MB

Testnet

  • https://api.testnet.solana.com - single Solana-hosted api node; rate-limited

  • Maximum number of requests per 10 seconds per IP for a single RPC: 40
  • Maximum concurrent connections per IP: 40
  • Maximum connection rate per 10 seconds per IP: 40
  • Maximum amount of data per 30 second: 100 MB

Mainnet Beta

Endpoints*

  • https://api.mainnet-beta.solana.com - Solana-hosted api node cluster, backed by a load balancer; rate-limited

Rate Limits

  • Maximum number of requests per 10 seconds per IP: 100
  • Maximum number of requests per 10 seconds per IP for a single RPC: 40
  • Maximum concurrent connections per IP: 40
  • Maximum connection rate per 10 seconds per IP: 40
  • Maximum amount of data per 30 second: 100 MB

*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.
