Api Endpoint

Tereno Base Chain Snapshot

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.
