Read Ethereum blocks and chain data through a hosted JSON-RPC endpoint.
Read-only Ethereum JSON-RPC for lightweight development and blockchain lookups instead of paid Chainstack RPC capacity. Shared public infrastructure, not dedicated nodes, equivalent throughput, archive access or an enterprise SLA. Chainstack also offers its own free tier; this is an alternative provider, not a claim all Chainstack usage needs payment.
No fixed per-user allowance verified; fair-use restrictions and availability changes apply. Archive access has a separate request process.
