Solana JSON RPC
Solana's public JSON-RPC clusters expose the full read/write RPC surface — accounts, transactions, blocks, and WebSocket subscriptions — with no signup or API key required. They're free to call, but Solana's own docs are explicit that the shared public endpoints are rate-limited to roughly 100 requests per 10 seconds per IP and are not intended for production traffic, pointing serious usage toward a dedicated third-party RPC provider instead.
