Cross-merchant operator identity
Your customers arrive already verified.
An agent verified at another AgentScore merchant is known the moment it reaches you: less checkout friction, less fraud, and no KYC stack for you to build or maintain. Repeat agents resolve to the same operator on /v1/assess, even from a wallet you have never seen.
Two ways to onboard
Self-serve if you have engineers. Forward-deployed if you don't.
Self-serve SDK

What's in the SDK
Four pieces. Every rail, every framework, every check.
Multi-rail x402/MPP
One builder. Every rail you accept. x402 v1/v2 dual-read out of the box.
AgentScore Gate
KYC, age, sanctions, jurisdiction. One middleware call. Auto-mints sessions on missing identity.
Stripe multichain
Multichain payment intents for Stripe SPT, card, and Link. Wallet capture on settlement.
Discovery
Skill manifests auto-published at /skill.md, /llms.txt, and OpenAPI.

Live in production today
Live storefronts. One stack.
Martin Estate ships the full multi-rail set (Stripe SPT, MPP on Tempo and Solana, x402 on Base); Sayer & Stone ships the same rails minus Solana. Martin layers in AgentScore Gate (KYC, age 21+, sanctions, US-only) because wine is regulated; Sayer & Stone doesn't need to.
Martin Estate sells wine to AI agents.
When an agent buys a bottle, AgentScore confirms a real, 21+, US, sanctions-clear human is behind it and takes the payment. Real per-state tax at checkout.

FAQ
Questions merchants ask
What does AgentScore Commerce actually do?▼
AgentScore Commerce is a merchant SDK that accepts payment from AI agents and gates routes on compliance. It ships identity middleware, multi-rail 402 payment handling, and discovery manifests, so a merchant adds agent checkout without building the rails or the identity plumbing.
Which frameworks does the SDK support?▼
Eleven, across Node and Python. On Node: Express, Hono, Fastify, Next.js, and Web Fetch. On Python: FastAPI, Flask, Django, AIOHTTP, Sanic, and ASGI.
Which payment rails can a merchant accept?▼
Stripe shared payment tokens, plus USDC over the Machine Payments Protocol on Tempo and Solana and over x402 on Base. A merchant can accept any subset; the 402 challenge advertises whichever rails that merchant has enabled.
Do merchants have to run KYC themselves?▼
No. AgentScore Gate runs the checks and AgentScore runs the verification, through Stripe Identity with OpenSanctions screening. The merchant declares a policy (KYC, age 18+ or 21+, sanctions, jurisdiction) and receives allow or deny with reason codes. Merchants never handle or store identity documents.
What happens when an unverified agent hits a gated route?▼
The gate returns a 403 carrying instructions the agent can act on, and mints a verification session inline so the agent can send its human through verification and retry. An unverified agent is not a dead end; it is a buyer that has not verified yet.
How do merchants get started?▼
Two ways. Self-serve, by installing the SDK and configuring a policy. Or Forward-Deployed Engineering, where AgentScore engineers embed and ship the integration end to end. Martin Estate and Sayer & Stone were both built that way.
