What is the current state of Base?
What is the current state of Base? Latest block number, timestamp, base fee and suggested gas fees in a single cheap call with no parameters — the fastest way to test an x402 payment loop end to end. Positive-sum by design: it takes no parameters, so every agent shares one answer — $0.02 if you are the first inside the freshness window, $0.01 for everyone after you.

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.
