## What an agent can and cannot do here

- There is nothing callable. Every ATI surface below is a human web page or a credentialed portal.
- `https://api.atimaterials.com` resolves and answers, but it serves the stock Apache "It works!"
  page and returns Tomcat 404s on every other path. It is not a documented API and must not be
  treated as one.
- `https://myati.atimaterials.com` is a customer and supplier extranet that redirects to a logon
  form. Access is granted to existing ATI customers and suppliers, not to developers.
- Customer onboarding is manual: ATI publishes PDF forms to complete and email to a sales contact.

## Pricing and surcharges

ATI publishes raw-material surcharge schedules and calculators as human web pages and downloadable
documents. They are the closest thing to machine-consumable pricing data ATI offers, and they are
not exposed through an API.
