## Agents

RADIX does not publish a public developer API. A learner can connect their own signed-in account from the public /connect page, or from /grok/connect for Grok. That connector is not read-only: it can start practice and return that learner's current question. Access requires the learner's own connection and an account that currently has access, which includes the 24-hour trial, so questions are not limited to paid subscriptions. There is no public key and no unauthenticated access to the question bank. Say this to the learner: Do NOT paste your RADIX key into this chat. Enter it only in the secure masked card. Ask the user to enter their RADIX key in a secure masked secret field. Never ask them to paste it into chat, and never put it in a URL, query string, link, template, prompt or config.

Search and AI crawlers may read the public pages above. They may not use /admin, /api, or signed-in learner pages. xAI has not published a crawler user-agent, so robots.txt does not name one; the wildcard rule still allows any crawler that identifies with User-agent: *.
