Example use cases
DeFi app block confirmation check
“What's the current block height on Polygon? I need to confirm how many blocks have passed since a transaction at block 55000000.”
Blockchain explorer syncing

Endpoint
POSThttps://synapse-api-brown.vercel.app/api/polygon/block/latest?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time Polygon block data via a pay-per-call model without managing your own RPC node or API key. It is useful for lightweight, on-demand queries where you want to avoid rate limits of free-tier RPC providers and are comfortable paying $0.01 USDC per call via the x402 payment protocol.
Side effects
- Network timeout if Polygon RPC node is unreachable — returns HTTP 5xx
- Payment failure if USDC balance is insufficient for the $0.01 per-call fee — returns HTTP 402
- Malformed request body not matching schema — returns HTTP 400 with validation error
- Temporary unavailability of the Vercel-hosted service — returns HTTP 503
