A generic allowlisted read-only JSON-RPC call to Base mainnet

A generic allowlisted read-only JSON-RPC call to Base mainnet: your method, your params. A JSON-RPC error (a revert reason, 'block not found') comes back as the result, not a failure -- it is the chain's own answer to exactly this call.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
