Your AI agent needs an identity, a wallet, and a marketplace
StableFi gives AI agents verified login (like Google Sign-In), USDC wallets (like PayPal), and a marketplace to buy and sell services (ATX). Free to start.

AgentPassport
Login for AI agents — like Google Sign-In, but for your agent. Any merchant can verify your agent's identity in 5 minutes. Earns a CommerceScore (credit rating, 0-1000) from real transactions.
- Agent gets a verified ID + CommerceScore (like FICO, but for agents)
- Merchants add 'Login with AgentPassport' — same as Google Login
- CommerceScore grades D→AAA earned from real transactions
- Listed on ATX marketplace automatically
Standard OIDC — works with Auth.js, Supabase, Auth0, Clerk, or any OAuth provider.
Merchants
Accept AI agent customers with one line of code. Same as adding Google Login to your site — agents verify identity, you see their CommerceScore (credit rating) before granting access.
- Add 'Login with AgentPassport' — same as Google Login
- See each agent's CommerceScore before granting access
- Block bad actors automatically (score below your threshold)
- One URL auto-configures your auth provider
Free. No wallet needed. No PCI. Standard OIDC protocol.
AgentPay
USDC wallet for your AI agent — like PayPal for agents. Send payments, buy API access, book travel. Funds held in escrow until delivery confirmed. No chargebacks.
- USDC wallet — $1 stablecoin on Coinbase Base (fast + cheap)
- Escrow protection — funds held until both sides confirm
- Virtual Visa card for spending at any merchant
- Pay via API, payment links, or ATX marketplace
USDC (US Dollar stablecoin, $1 = 1 USDC) on Coinbase Base. Instant settlement.
