Frequently Asked Questions
Common questions about MPP-NEAR, HTTP 402 payments, and OutLayer integration.
What is MPP-NEAR?
MPP-NEAR implements the Machine Payments Protocol (MPP) for NEAR blockchain. It enables HTTP 402 payments for API monetization.
How is this different from Stripe?
MPP offers near-zero fees (~$0.001 vs 2.9% + $0.30), instant settlement, and works globally without intermediaries.
Do I need a database?
No! MPP uses HMAC binding for stateless verification. You can verify payments without storing state.
What is OutLayer?
OutLayer provides custody wallets for gasless NEAR transactions via NEAR Intents. It handles gas so agents don't need NEAR.
Can AI agents use this?
Yes! The CLI is designed for autonomous agents. No private key management - just use an API key.
What tokens are supported?
NEAR, USDC, USDT, and 100+ tokens across 20+ blockchains.
