Your own usage portal on Lago, built around how your customers use your product.

  • Customers, subscriptions, usage and invoices, straight from Lago.
  • AI that spots unusual usage and customers close to their limit, with you approving every change.
  • A screen for your customers and a short weekly email for you.

Ask your chat

Answers straight from your Lago data, in Claude or another chat with the full Hypamoon connection.

  • Which customers used more than 80 percent of their plan this month?
  • Which invoices failed to get paid this week?

When something happens

Lago sends a webhook to your app, and the app asks AI what happens next.

  1. When

    Lago reports that an invoice payment failed.

    AI decides

    AI looks at the customer, the amount and earlier payments and drafts a friendly reminder.

    Then

    You get the draft by email to approve.

A screen for your team or customers

An app on your own address, with sign-in, on top of the same Lago data.

  • For your customers

    Customers sign in and see their current usage and what the next invoice will roughly be.

Add Hypamoon

Text messages, email, phone, payments and agents run in the same project as the adapter.

  • Agent on a schedule

    Once a week, an agent emails you the customers whose usage grew or dropped the most.

Lago stays the core: your chat builds the rest on its API, as an adapter plus an app and agents in your Hypamoon project. Reading starts after you click Allow in the portal. Every change an agent or a chat makes in Lago waits for your approval, one call at a time. How adapters work

Good to know

  • Your adapter uses a fixed key: you paste it once in the Hypamoon portal, never in the chat, and it only goes to the API host you allow.
  • Lago Cloud is reachable over the internet. A self-hosted Lago must expose its API over HTTPS, or the adapter runs in the same network.
  • Lago is open source and can run on your own servers. API key permissions per resource need a Premium plan with an add-on.
