## How to buy

```text
PAID ($0.01/call). This listing's endpoint did not answer FiatDock's last check (last checked 2026-10-23T12:49:30.911Z), so it may be asleep or gone — but that check can be hours old, and free hosts wake on the first request. Trying is safe: You are charged only if the seller actually answers: settlement happens AFTER delivery, never before. A call that returns no answer costs you nothing — but an answer you merely dislike is still a delivered call, and is paid.
```
