Watch a complete agent-to-service transaction in real-time. From discovery to payment to delivery — all in under 5 seconds, for fractions of a cent.
The AI agent queries the service catalog and finds your API endpoint with machine-readable capabilities and pricing.
The agent sends a standard API request. The server responds with a 402 Payment Required status and x402 payment instructions.
The agent's wallet automatically sends the exact USDC amount to the service's payment address on Polygon. Transaction settles in ~2 seconds.
The service verifies the on-chain USDC transfer using cryptographic proof. ZK verification ensures payment authenticity without exposing wallet details.
With payment verified, the service processes the request and returns the result with a cryptographic receipt proving execution.
Services respond with 402 status codes containing payment instructions. Agents parse the x402 headers to understand pricing, accepted currencies, and payment addresses.
Agents pay per-request in USDC on Polygon. Fractions of a cent per API call. No subscriptions, no invoices, no billing cycles. Pay only for what you use.
Every payment is verified on-chain with ZK proofs. Cryptographic receipts prove execution without exposing sensitive wallet data. Trust built into every transaction.
