The math is simple

At $100/month in API usage on Standard tier, you pay $125/month (25% margin = $25 extra). With Lifetime, you pay exactly $100. The $299 unlock pays for itself in 12 months — then you save $25/month forever.

Heavy user at $500/month? You're saving $125/month. The $299 pays back in under 3 months.
