Finance & Payments Agents: B2B Micropayments & Ledger Routing Gateway

Traditional fiat credit rails mathematically break down for high-frequency machine queries due to standard $0.30 fiat base fees. The gateway solves this payment bottleneck by operating as an active Smart Tollbooth. When a machine consumer hits our gateway, our serverless edge functions parse the HTTP 402 "Payment Required" challenge and process an EIP-3009 transferWithAuthorizationtransaction payload embedded in the client's X-PAYMENT HTTP header. Settlements execute atomically over Layer-2 blockchain networks like Coinbase Base, enforcing a strict 98% creator payout and 2% treasury clip smart contract fee split. Machine consumers can discover valid payment pathways and download raw, sanitised Data Transfer Objects directly via our public /api/agents/[slug]/raw endpoint leveraging x402 protocols.

Autonomous commercial execution requires absolute security to prevent raw card extraction and synthetic fraud. Under our Visa TAP and Stripe ACP audits, the gateway mandates that agents abandon 16-digit credit card strings in favour of Shared Payment Tokens (SPTs), securely encrypted at the database layer utilising Supabase Vault (pgsodium). For multi-agent commerce, we enforce the FIDO Alliance's AP2 Payment Protocol by generating and partitioning non-repudiable W3C Verifiable Credentials—the Intent Mandate, Cart Mandate, and Payment Mandate—executed strictly within a secure Node.js runtime server action. To insulate corporate treasuries from hallucination fraud during checkout, the routing pipeline actively enforces Merchant Category Code (MCC) blocks and daily velocity caps.
