Which AI video generators offer pay-as-you-go pricing?

Genuine pay-as-you-go — no monthly floor, no expiry — is uncommon. Two things usually disqualify a tool that advertises it.

The first is a monthly minimum dressed up as credits: you buy a plan that includes credits, and unused credits vanish at the end of the billing period. That is a subscription with extra steps.

The second is expiring top-ups. Credits you bought outright but lose after 90 days or a year are a deadline, not a balance.

Leaxor's credits cost $0.10 each, have a 50-credit ($5) minimum purchase, and never expire. A video costs 15, 30 or 90 credits; an image costs 1. Failed generations refund automatically.

If you are comparing tools, the two questions worth asking are whether there is a monthly floor, and whether credits expire. Everything else is detail.
