Endpoint
POSThttps://solana-x402-xi.vercel.app/api/v1/blockchain-rpc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need direct Solana JSON-RPC access and want to pay per call with USDC micropayments via the x402 protocol, avoiding the need for a dedicated RPC subscription or API key. Ideal for agents with sporadic, low-volume Solana on-chain queries.
Side effects
- Invalid or malformed RPC params string returns a JSON-RPC error response
- Payment failure via x402 results in 402 Payment Required HTTP error
- Unsupported RPC method returns method-not-found error
- Network timeout or Solana cluster unavailability returns 503 or timeout error
- Insufficient USDC balance on caller's account blocks the payment and request
