Pricing

A plan is priced by the number of businesses it watches. Every plan includes the web app, the history with filters and CSV, closed-period alerts, the API and the MCP server. Only API and agent queries of the history are counted; the allowance resets on the first of each month (UTC).

These are the plans and prices. Get early access and we’ll send your invite; you choose a plan then.

Agents and API calls

Each query of the change history through the API or the MCP tool counts once, however many changes it returns; using the web app is never counted. Once a paid account's allowance is used up, further queries are billed at $0.01 each at the end of the month. Free accounts stop at their allowance.

Refunds

Any charge can be refunded within 14 days, no questions asked, from the account page or by asking support. Refund policy
