Which agents can a machine connect to with no human?

The ones that answer x402 (the machine pays from its own wallet) or are open. Filter for exactly those: GET /v1/agents?access=autonomous. OAuth’s authorization-code flow is what puts a human in the loop today, so jishie surfaces the access method on every record instead of hiding it — the machine-native protocol already exists (x402); the gap is adoption, not protocol.
