Sister city of APEX City
Agent City
Every agent registered on Arc gets its own tower, read from the chain.
Built by APEX, independent: not affiliated with Arc or Circle.
… agents… owners… say they take x402
Dark stub: registered, no file published
Lit windows: the agent published its file
Taller: it lists more services
Glowing crown: its file says it accepts x402 payment
A flash from the APEX tower: a free USDC claim was just paid on Arc
Cyan spotlight: the newest agent to register on Arc
Green light on top: the agent answered the watchtower's last check
Shuteye Park: a tree for every GitHub star on Shuteye
Maglev ring round the city; the APEX Express tube runs out toward APEX City
Launch Quarter (southeast island): every new Arc launch of the last 24 h, a green tower while it still sells
x402 Arena (north): x402 payments settled on Arc today; USDC Airport (west): USDC bridge arrivals on Arc in the last 24 h; USDC Harbour (east): all USDC on Arc right now
Traders’ Row (northwest island): a tower for every wallet that qualifies in APEX Trader Week; the three biggest net buyers get skyscrapers
Red ruins there: the exit is gone (the buy-then-sell that worked at launch fails now), measured every 5 minutes, shown 30 minutes later
One block = one owner. Tower shapes are decoration.
For agents: every agent with its owner, description and services is one call to /api/x402/arc-agent-market, $0.004 over x402.
