FAQ

Do you store my emails permanently?

No. All emails are auto-deleted after 4 hours (free) or at your key's expiry. We store nothing long-term.

What personal data do you collect?

None. No account, no email address from you, no IP logging beyond rate-limiting. The API is designed to be used without revealing anything about yourself.

Why Lightning only?

Because it requires no signup, no card, and no identity from you. Pay sats → get key → use API. That's the whole flow.

What Lightning wallets work?

Any standard Lightning wallet: Phoenix, Wallet of Satoshi, Breez, Cash App, Strike, Zeus, Muun. If it can scan a QR code and pay an invoice, it works.

Can I use this for bulk / commercial testing?

Yes — that's exactly the use case. Tier L gives you 100,000 requests over 90 days for $30. Buy as many keys as you need; no per-account limits.
