X402 Integration

UCII x402 Integration

UCII uses x402 as the economic authorization layer.

Identity remains the primitive.

x402 provides payment authorization for infrastructure operations.

Payment Flow

1. Client requests a protected UCII operation.

2. UCII returns HTTP `402 Payment Required`.

3. Client submits payment authorization proof.

4. UCII verifies settlement.

5. Operation executes.

6. Settlement receipt is recorded.

Discovery

UCII exposes:

This endpoint provides:

  • service identity
  • supported capabilities
  • operation pricing
  • settlement network
  • supported x402 operations

    • ---

    Settlement

    Current settlement configuration:

  • Protocol: x402
  • Currency: USDC
  • Network: Solana
  • Model: pay-per-operation

    Design Principle

    UCII does not replace x402.

    UCII uses x402 as the economic access mechanism for cryptographic identity infrastructure.

    Identity is the primitive.

    x402 is the economic authorization layer.
