What is the current state of Base? Latest block number, timestamp, base fee and suggested
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.
