# Epiphani Alerts > Track anything on the web and get told the moment it changes in the way you care about: price drops and targets on any store, back-in-stock, page and region changes, keywords appearing or disappearing, news on a topic, competitor promotions, product launches and pre-orders, and any plain-English condition a model checks against the page. ## What it does - Eight alert types: price, restock, change, keyword, news, promo, launch, custom. - Checks every 5 minutes to every week, per alert. - Rules read structured data first (schema.org Offer, meta price tags, feed item IDs); a model judges whether a change is meaningful, whether a promotion appeared, and whether a plain-English condition is met. - Delivery by email, SMS, Slack, Discord, Microsoft Teams, any webhook, and Chrome extension notifications; daily digest and do not disturb hours. - Every alert can be created, edited, paused, snoozed, duplicated, shared as a public link, archived (history kept) and deleted (Trash keeps it 30 days). - Chrome extension: track any product or page from the toolbar; pick a page region by clicking it. - Full JSON API with a bearer token: https://alerts.belstone.com/openapi.json - MCP server for assistants (Model Context Protocol): https://alerts.belstone.com/mcp (eight tools, bearer token) - Where to buy used at quality: https://alerts.belstone.com/api/v1/sources?q= ## How to verify - Health: https://alerts.belstone.com/api/v1/health - Capabilities with mechanisms: https://alerts.belstone.com/capabilities
