Autonomous Commerce Infrastructure for AI Agents, Enterprises, Merchants & Sovereign Identity Systems
Build programmable payment flows, identity-based settlement endpoints, AI agent transactions, QR commerce, wallet routing, and non-custodial stablecoin execution using one unified API stack.
WorldBankPay™ and DOMAINLINK™ give enterprises and developers the infrastructure to create, verify, route, execute, and settle transactions through programmable identity endpoints — without relying on legacy card processors, acquiring banks, or percentage-based interchange economics.
Identity → Routing → Execution → Settlement. One API.
Built for the AI Commerce Economy
Traditional payment systems were built for humans, cards, banks, processors, and settlement windows.
AI agents require something different:
-
API-native execution
-
machine-readable identity
-
deterministic settlement
-
programmable permissions
-
direct wallet routing
-
real-time verification
-
low fixed-fee infrastructure
-
autonomous transaction logic
WorldBankPay™ and DOMAINLINK™ provide the missing execution layer for autonomous commerce.
What You Can Build

Example API Flow
Step 1 — Create a DOMAINLINK™ Identity
A merchant, enterprise, user, or AI agent receives a programmable identity.
Example: agent.pay.meta
Step 2 — Attach Wallet Settlement Route
The identity is connected to approved wallets across supported chains.
Step 3 — Create Payment Intent
WorldBankPay™ creates a payment request for the identity endpoint.
Step 4 — Execute Payment
Human user or AI agent executes payment through the API, QR code, or checkout page.
Step 5 — Settle Directly
Funds settle directly to the approved wallet endpoint.
Step 6 — Record Proof
The system records transaction metadata, wallet route, identity endpoint, and settlement proof.
