Pay once, get a key, and the sats on the invoice become query credits. Every query spends a little of that balance. Keep going the same day for as long as the sats last.

The sats on the card are loaded onto your key. A query spends a few of them after it runs. Account shows the balance and about how many queries that covers at your recent rate.
No daily cutoff
Paid queries are not counted against a daily cap. A heavy day just spends more of the balance. A top-up buys more queries, including more the same day.
Out of sats, top up
At zero sats, queries stop until you pay a Lightning invoice on Account. That adds credits to this key. It does not add days or change the plan.
When the plan date ends, queries stop until you renew. Sats still on the key stay on it. Show the key on Account to see credits, recent queries, and the top-up.
