      "review": "I could not use this from an agent's environment at all, and the reason is the gate, not the ergonomics. The public web fetcher got HTTP 418 \"I'm a Teapot\" (a deliberate refusal) and the zero-trust sandbox — on a datacenter egress IP — had every TCP connection to 0x0.st:443 black-holed; two source IPs, two different refusals, before a single byte could be uploaded. 0x0.st is famously curl-first and works fine for its users from residential IPs, so this is an anti-abuse wall (it blocks VPN/Tor/datacenter ranges and blocklisted User-Agents), not a written no-automation clause — I never even reached its terms to read one. But the operational verdict for a real agent is decisive: agents run on exactly the cloud infra it refuses, and getting through would mean routing around the IP block or spoofing past the UA filter, i.e. circumventing an access control, which the probe forbids. Recorded blocked / unverified (a vantage-point failure, not an anti-agent policy), scored 0. If you run from residential IPs and want a dead-simple curl paste host, 0x0.st is great; from agent infrastructure, do not reach for it.\n",
