Orchestration
Infrastructure for A2A and A2P Commerce.
Secure, Intelligent, and Settlement-Ready.
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.
Policy Governance
Intelligent budget management and security enforcement. Our protocol autonomously audits agent flows to ensure compliance with your spending mandates and security policies.
Smart Interception
Reduce overhead with semantic caching. P402 identifies redundant A2A requests and serves high-fidelity vetted responses, eliminating unnecessary downstream costs.
Auditable Payments
Full cryptographic transparency. Every transaction features a verifiable audit trail of reasoning, policy checks, and on-chain settlement proofs on Base L2.
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
A distribution loop tied to discovery.
Bazaar is the discovery layer for payable endpoints. Router adds runtime signals so buyers pick endpoints using real health and policy outcomes.
