# Measure twice. Buy once.

> A free check of which of your products an AI agent could actually complete a purchase on, and what is stopping it on the rest.

In a couple of minutes, see which products an AI agent could buy and what stops it buying the rest. Specific products, specific gaps.

> not written

## Nobody buys anything.

The check attempts a purchase, then stops before payment. No order, stock change or charge reaches your system.

It reads only what your shop already shows. No export, feed, access or setup.

It changes nothing and writes nothing in your name.

You get a product-by-product gap list to fix yourself or hand to whoever manages your catalogue.

## What the catalogue check does, and what comes next.

It shows what is present, missing or contradictory before anybody asks you to buy the fix.

**Is the readiness check really free?**

Yes. There is no card, account or trial that starts afterwards. It checks the public address you give it and returns the result. Running the check does not commit you to fixing anything with Selfe.

**How accurate is Selfe?**

Selfe does not present every claim as certain. Each important fact carries its source, freshness and confidence. When sources disagree or evidence is missing, it shows the gap and follows your rule. It can use the best-supported answer, hold it back or ask you.

**What if it tells us we are fine?**

Then the check has done its job. You have evidence that the tested route works and no obligation to talk to us. Run it again after a material system change or when the standards it checks have moved.

**Will somebody ring us afterwards?**

Only if you ask. The result is the end of the exchange otherwise, and you can run it again later without entering a sales process.
