CourseMate

One key, one term, no account.

CourseMate runs at cm.innotel.tech — the app already knows that, so the only thing to buy is the key. Pay once and it works for 120 days, on as many lectures as you sit through, and then it is deleted from the gateway.

· Paste it into CourseMate → Settings → API key
· Works with any OpenAI-compatible client too
· Endpoint: gateway.innotel.us/v1
· Spend inside the key is capped at 40% of its price

The server the app talks to

https://cm.innotel.tech

Try the key from the command line

curl -s https://cm.innotel.tech/api/health \
  -H "Authorization: Bearer $COURSEMATE_KEY"

A key answers only while its window is open; anything else is refused with 401, which is what the app reports as a bad key.

Where to send the receiptKeys

1 × $19.00 = $19.00

Payments are processed by Stripe. The key is minted the moment payment confirms and shown once on the confirmation page; if you lose it inside the window, reload that page rather than paying again.
