Endpoint
POSThttps://synapse-api-brown.vercel.app/api/solana/rpc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call, no-subscription access to Solana RPC functionality without managing your own node or RPC provider credentials. It is well-suited for AI agents that make occasional or unpredictable Solana queries and want to pay micro-amounts per call via USDC x402 rather than committing to a monthly RPC plan.
Side effects
- Invalid RPC method name returns an error response with code -32601
- Malformed params array causes a parse error or invalid params response
- Network congestion on Solana may cause timeouts or slot-related inconsistencies
- Submitting an invalid or expired transaction returns a transaction simulation failure error
- Missing or invalid x402 payment header results in a 402 Payment Required response before execution
