The monthly-reveal bookends (pre-roll & end-card). Preview exactly what a competitor will see, then approve. Any edit sends it back to pending — and a creative only shows once it's approved, its sponsor is active, and it's enabled.

NMAO's own promos — shown in the Arena when no paid sponsor is live, so the slot is never wasted.

Views (times the ad was watched), completion rate, avg watch time, clicks & CTR per sponsor.

Just set a monthly price — that's all it takes to make a plan sellable; checkout builds the Stripe price automatically. The Stripe price ID is optional (only if you'd rather point at a fixed price you made in Stripe).
