Endpoint
POSThttps://synapse-api-brown.vercel.app/api/solana/block/latestWhen to prefer
Use this endpoint when you need fast, pay-per-call access to the latest Solana block without managing your own RPC node or subscription. It is ideal for lightweight agents that need occasional Solana chain-tip lookups billed via USDC micropayments rather than a monthly RPC plan.
Side effects
- Solana RPC node unavailable or rate-limited — returns 5xx error
- Payment not processed or x402 micropayment rejected — returns 402 Payment Required
- Network congestion causing stale or delayed block data
- Malformed request body — returns 400 Bad Request
- Solana mainnet experiencing an outage — endpoint may return empty or error response
