Every check is deterministic: no model runs in this path, so two calls on the same page return the same verification. Failed checks are DECLARED alongside the content, never hidden.

Buy 20 GB of French West Indies residential proxy bandwidth at 2.60 USD per gigabyte, the best rate in the range, delivered as a proxy key valid for 30 days. The exit is a real FTTH home line in the French West Indies on Outremer Telecom / SFR Caraibe (AS20776), reverse DNS ftthcc.*.sfrcaraibe.fr. Geolocation is split across databases and we say so rather than pick the flattering one: ipinfo and ipwho.is place it in Martinique (MQ), ip-api and db-ip place it in mainland France (FR). Reachability, carrier and proxy-blacklist status are probed from the public internet before every sale: the address currently comes back clean, not flagged as a proxy or VPN. If no exit is verified live you are not charged. Designed for agents running long crawling campaigns or continuous monitoring, where bandwidth is consumed steadily over weeks. No account, no subscription: one payment, one key, metered per gigabyte until exhausted.",
