This site is **public**. All content and discovery endpoints are anonymous and read-only. The pilot request form submits to a secure webhook — no API key required to submit.

## How an agent should identify itself
Send a descriptive `User-Agent` header. Respect `robots.txt`. One pilot request per organization please.
