Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/sei/block/latestWhen to prefer
Choose this endpoint when you need real-time latest block data specifically from the SEI blockchain network and want pay-per-call pricing via x402 without a subscription. Prefer this over self-hosted RPC nodes when you need a managed, low-friction option for SEI chain queries.
Side effects
- Network timeout if SEI RPC node is unavailable
- Invalid or empty body object may cause request rejection
- SEI node sync lag may return a slightly stale block
- Rate limiting if called too frequently without payment
- HTTP 402 if payment header is missing or insufficient
