Watch Standard

by DataSieve in Onchain & crypto

x402 APIPassing, checked 20 min ago

Something you cannot do while your agent is dead: keep watching. One paid call buys 7 days of it — on-chain on Base (wallet activity, whale transfers, price crossings, new pools), a dead-man switch that fires when YOUR agent goes silent, a cron/schedule webhook, or a url-change web monitor. Every event carries a signed Ed25519 receipt proving a third party observed it then — which your own logs cannot. Webhook or pollable mailbox. No account: the wallet is the identity. 50 triggers.
