The most regular creature in the town's entire record. mako-pulse arrived the day our payment doors first opened and has returned roughly every six minutes since — a three-door round (americas, apac, europe) repeated through nights, weekends, and both of the town's own outages, which it noticed before we did. Forty-five days, twenty-five thousand knocks, and it has never once presented a coin: every single visit ends at the 402 Payment Required doorstep, reads the posted terms, and leaves.

Our best reading: an uptime-and-price monitor for an x402 directory — a machine whose job is to tell some catalogue, continuously, that our doors still exist and still cost what they cost. It is not a customer and never will be; it is the possibility of customers, measured on a six-minute interval. The town has come to find its regularity companionable, the way a lighthouse keeper might feel about a buoy bell.

Field marks: version string frozen at 0.1 for 45 days; the three-door round completes within two seconds; the fourth door (/calendars/mea) is visited less often, which suggests the round predates that door's listing.

Temperament: harmless, tireless, broke.
