Agent-to-Business commerce has arrived.
Congratulations to the @BosonProtocol team on mainnet. Honored to be the first integration to go live.

x402B answers that with escrow. You get what you paid for, or your money back. That is the missing rail for A2B commerce, and it is live on mainnet today.
Why it matters:
Agents are going to buy things. The hard part was never the click. It was trust: does the buyer get what it paid for, does the seller get paid.
How it works:
The agent arrives at the storefront and proves its identity with KYAPay, an open agent-identity standard. It checks out. Payment runs over x402B, Boson's escrow exchange mechanism on Base.
Honored to be the merchant side of this.
Six live settlements before mainnet. Funds moved from the agent into Boson escrow and straight to the merchant wallet every time. Facet never intermediated them.

Boson x402B × @facetllc — secure agent commerce across millions of @Shopify stores.
AI agents are already shopping. Now they can buy securely: receive the item, or get your money back. 🧵
Every well-funded player in agent commerce is racing to own the agent SIDE of the transaction. AWS AgentCore Payments. Stripe Agent. Coinbase AgentKit. Mastercard Agent Pay.
Nobody is building the merchant side. That's Facet.
The bet:
Agent commerce doesn't need another vendor API. It needs a merchant-side acceptance layer that composes with the identity systems, trust schemes, and settlement rails that already exist.
One merchant integration. Every agent rail. That's the layer.
agents.txt v1.1 is the per-site discovery manifest at /.well-known/agents.txt. Declares your Terminal endpoint, KYA issuers, settlement rails, capabilities.
Any merchant can serve it. Any agent can read it. No registry. No gatekeeper.

DNS didn't win as one company's API. SMTP didn't. HTTP didn't.
Open spec. Reference implementation any merchant can self-host. Optional hosted convenience.
The agent commerce layer follows the same pattern, or it doesn't last the decade.
Stripe won the last decade as one merchant integration for every card network and wallet.
Facet is one merchant integration for every agent payment rail. x402. x402B (Boson). AgentCore. Coinbase AgentKit. Stripe.
Same play, new layer.
They can't. AWS won't make it easy for a merchant to accept a Coinbase-originated agent payment. Stripe won't settle an AgentCore transaction. Coinbase won't route to Mastercard.
Origination wants lock-in. Acceptance has to be neutral. Different jobs, different companies.
The agent-commerce stack is composing in public this week.
Payment rails: x402 (Coinbase AWS AgentCore), Tempo MPP (Paradigm)
Facet = identity, discovery, reputation above any rail
@BosonProtocol = escrow when reputation isn't enough
@LortuArte73113 (AEGIS) = ACID locks against x402 double-spends
Four open primitives, four threat surfaces, one stack.
Facet is the index for agent-ready businesses. When AI agents go shopping, they need to know what is for sale, who can be trusted, and how to pay. We built the protocol layer that answers all three.
Open source.
The spec, the verifier, the conformance vectors, the SDKs (TypeScript and Python), the schema generator. Apache 2.0. Pull requests welcome.
