terms
Short, because the service is simple.
Use
proxycanary checks whether proxies work. Only submit proxies you are entitled to use. Do not use the service to scan, probe or map infrastructure that is not yours.
Rate limits exist so the service stays free for everyone. Working around them is the one sure way to get blocked.
No warranty
Results describe one moment in time from one vantage point. A proxy marked alive can be dead a minute later, and a target site may still refuse it. The service is provided as is, without warranty of any kind, and may change or go away without notice.
Liability
To the extent the law allows, proxycanary is not liable for any loss arising from use of the service or reliance on its results.
