### Description (declared)

Standing infrastructure for autonomous agents, paid per use over x402. Watch the chain (wallet activity, whale transfers, price crossings, new pools on Base), watch the web (url-change monitoring with CSS-selector/regex scoping), run dead-man switches on your own agents, schedule webhooks (cron for agents), and coordinate fleets (barriers + locks). Every event carries a signed Ed25519 observation receipt. Failed calls are never billed. No account; wallet is identity.
