The infrastructure of
agentic payments.
Protocols, architecture, implementation guides, and the business models powering a world where AI agents transact autonomously. Written by the team building Bankee.
Everything you need to build
agent-native payment systems.
From raw protocols to business models — structured content for engineers, architects, and founders building in the agentic payments space.
The Protocol Layer
The emerging standards and protocols that make agent-to-agent and agent-to-service payments possible — from x402 to AP2 to EIP-4337.

The Implementation Layer
Code-first walkthroughs for building real agentic payment flows — from protecting an endpoint with x402 to provisioning agent wallets with Stripe.

- Building a spending-limit guardrail for autonomous agents
- Agent authentication for payment APIs
The Architecture Layer
Design patterns and reference architectures for systems where AI agents transact autonomously — covering escrow, settlement, and kill switches.
