x402 Payments (Hedera)
Pay-per-use pattern: store protected bytes off-chain, record access terms separately (on-chain or config), gate HTTP resources with HTTP 402 + a self-hosted Hedera facilitator that verifies and settles native HBAR transfers.
Buyer → GET protected resource
├─ free / public → resource
└─ paid → 402 PAYMENT-REQUIRED
→ client signs HBAR transfer
→ retry with PAYMENT-SIGNATURE
→ resource server verify + settle via facilitator
→ PAYMENT-RESPONSE + resource
The resource server never holds facilitator keys. Settlement uses a funded ECDSA fee-payer account on the facilitator process.
