Endpoint
POSThttps://synapse-api-brown.vercel.app/api/plasma/block/latestWhen to prefer
Choose this endpoint when you need the latest plasma block data in a pay-per-call model without committing to a subscription, especially if you are operating across multiple blockchain networks and want a single unified API surface. Prefer this over dedicated node RPC calls when you lack direct node access or want simplified multi-chain querying.
