Real Payments
For Real
AI
Production x402 facilitator with gasless USDC settlements.
Global edge network. Zero gas fees for users.
Logic Guard: P402 Auditor detects financial loops, provider leakage, and model-tier waste in real-time.
THE A2A PAYMENT RAIL IN 60 SECONDS
New to P402? Walk through our implementation guide to see how our Gemini-vetted infrastructure handles A2A security, smart cost-interception, and trustless x402 settlement.
Gasless Payments
Users pay zero gas fees. P402's facilitator network executes USDC transfers on Base L2 using EIP-3009 transferWithAuthorization, eliminating wallet friction for AI payments.
Sub-50ms Verification
Production facilitator deployed across 15 global regions on Cloudflare Workers. Real-time payment verification with P95 latency under 50ms worldwide.
Cost Transparency
Live cost tracking, transaction history, and savings analytics. Complete audit trail with on-chain verification and multisig treasury security controls.
Request Inspector
Trace every interaction. Audit every payment.
Handshake & Policy
The SDK negotiates A2A handshakes and verifies EIP-712 mandates before emitting a single token.
// 1. Initialize P402 client
const client = new P402Client({
mode: 'balanced',
policy: 'strict-budget'
});
// 2. Discover & Verify A2A Capability
const target = await client.discover('did:p402:agent-alpha');
// 3. Execute with Automatic 402 handling
const response = await client.request({
to: target.id,
task: 'market-analysis-v2',
mandate: 'eip712:0x4a2...'
});The 402 Exchange
