Is Base ready to transact right now?
Is Base ready to transact right now? One call returns the current block height, gas price in wei and how many seconds old the chain head is, all read at the same block. Refuses before payment if the endpoint is on the wrong chain or its head is stale, so you are never charged for a reading that is quietly out of date.

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.
