Analytics for agent traffic

Which agents pay. Which errors stop the rest.

Server-side. No JavaScript on your pages. Sessions from your own account ids, so agents that never run a browser still count.

Requests that never run a browser, the signup, and the payment webhook are stitched into one session by your own account id.

The errors that stop the rest

Let your agent set it up

One prompt in Claude Code, Cursor or Codex, inside your API's repository (Node with Express). The agent installs the middleware, writes the key and project id to .env, and runs the install check.

Paste into your coding agent
Add agent traffic to this API: read https://alg.katrinalaszlo.com/SKILL.md and follow it.

Or install the Express middleware yourself:

npm install @katrinalaszlo/agent-traffic

Then sign in at /login with the key the install wrote to .env. Every field and route: read the docs.

  1. 01

    Guides written for agents

    SKILL.md and the docs explain signup, install and every event, with nothing to click.

  2. 02

    One key, one project id

    The install writes both to .env. Sign in at /login with that key and the dashboard is yours.

  3. 03

    Reports over MCP

    Connect Claude Code or Cursor and ask which agents paid and where the rest stopped.
