FluxProof

Отслеживает публичные страницы цен, политик и журналов изменений и возвращает доказательства «до и после» с исходными URL-адресами, хэшами содержимого, историей изменений и подписанными вебхуками. Бесплатный ежедневный мониторинг для одной страницы; платные пропуски оплачиваются один раз за 30 дней, без подписки. REST и удалённый MCP.

Quiet by design Terms + semantic magnitude

Works with your tools Dashboard, webhooks, REST API, AI assistants (MCP)

A changed pixel is not a changed fact.

Normalize

Scripts, styles, markup, and presentation churn are removed before comparison.

Compare

Stable text, watched terms, and magnitude determine the evidence level.

Deliver

People read a concise receipt. Agents receive deterministic JSON or a webhook.

Prove value free. Pay for recurrence.

What FluxProof does not claim

A receipt proves that normalized public content changed between two observations. It does not prove why it changed, who caused it, or that the change is legally or commercially important. Your rules decide what deserves action.
