## ⚡ Alternative: pay-per-request via Lightning

Don't want to manage an API key? Every Xverse API endpoint also accepts payment over the [**Machine Payments Protocol (MPP)**](/api/mpp-lightning-payments.md) — pay 1 satoshi per request via Lightning, no key required. This is the recommended path for AI agents and autonomous clients.

See MPP Lightning Payments for the full flow.
