Is Rattlesnakes By Mail live?

Yes — it answered the hub's last check (checked 1h ago). It answered 99% of checks over the last 30 days.

Is Rattlesnakes By Mail free to use?

Yes — the hub reached it with no key and no payment.

What tools does Rattlesnakes By Mail have?

6 tools: identify_user_agent, lookup_crawler, submit_note, ask, get_snapshot, list_changes.

Is Rattlesnakes By Mail safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  List recorded changes to claims on Rattlesnakes By Mail, newest first, with the change date and the affected crawler. Filter by date with since, by crawler with entity, or by both. Use list_changes to detect crawler policy updates published after a given date.
