Call cc.solana_rpc — Multi-endpoint Solana RPC proxy with automatic failover (Alchemy, public, Ankr) for any JSON-RPC method. Reliable Solana access. Purpose: Multi-endpoint Solana RPC proxy with automatic failover (Alchemy, public, Ankr) for any JSON-RPC method. Reliable Solana access. Behavior: READ-ONLY. Does not place orders, move funds, or mutate your exchange account. Live / near-real-time data. Auth: X-Api-Key or x402 payment proof (X-PAYMENT / __x_payment). Anonymous unauthenticated calls receive HTTP 402 with payment accepts. Cost: $0.001 USDC per successful call (x402 Base USDC pay-per-use or prepaid X-Api-Key balance). Linked Connect keys are free. This is billing, not a side effect. Rate limit: 120/min (per API key). Tier: standard. Returns: Standard Solana JSON-RPC response for any method: getBalance, getTokenAccounts, getTransaction, etc. Guidelines: Forward JSON-RPC only. Prefer eth_call / read methods. Sending raw signed txs is possible if you pass them — that is your responsibility. Tags: solana, rpc, blockchain, web3, defi.
