Turn website changes into live market signals.
Monity turns website changes into data you can use. The values and lists it reads on a page arrive with every alert: as rows in Google Sheets, as signed JSON to your webhook, or through the REST API.

Read, not just seen
Monity reads the data on the page, not just the pixels.
A few minutes after a task is saved, Monity’s AI finds what you asked about, a price, a list, a table, and proves it reads it the same way twice. Every check then compares it item by item.
- Single values, lists and tables
- Or pick a value yourself: Number, Regex, JSON path
Rows
Every alert as a row in Google Sheets.
Connect a sheet and each alert adds a row with the time, the page, the AI summary and the value you extract. Several tasks can write to one sheet, which gives you one log across all of them.
Signed JSON
Webhooks your systems can trust, and an API to pull from.
Each alert can post JSON to your endpoint, signed with HMAC-SHA256 so you can verify it came from Monity, and retried twice if your endpoint fails. The REST API lists monitors and their checks with read or write keys.
