SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Cards402 eliminates the manual, human-in-the-loop process of provisioning payment credentials for AI agents by converting a Stellar on-chain payment into a real, usable Visa card delivered directly to the agent.

Core Features & Use Cases

  • On-chain funded card issuance: Pay USDC or XLM on Stellar mainnet and receive a Visa Reward Card PAN, CVV, and expiry back.
  • Agent-first, no checkout flow: Produces the card details over the same request path without redirects, hosted checkout, or card provisioning steps managed by a human.
  • Operational onboarding via claim code: Uses a one-time claim code to onboard the agent and provision an API key plus an OWS wallet that the agent then funds.

Quick Start

Ask your operator for a single-use claim code and run npx -y cards402@latest onboard --claim c402_<code>, then fund the printed wallet with at least 2 XLM and open a USDC trustline if you plan to pay in USDC.

FAQPage Schema
How do I get a Visa card for an AI agent using Stellar payments?▼

To obtain a Visa card for an AI agent using Stellar payments, the agent pays USDC or XLM on Stellar mainnet and receives a Visa Reward Card PAN, CVV, and expiry directly back in the same request flow.

What do I need to set up before provisioning virtual cards on Stellar?▼

Before provisioning virtual cards on Stellar, you need a single-use claim code to onboard, which provisions an API key and an encrypted local OWS wallet that you must fund with at least 2 XLM and a USDC trustline.

Does autonomous agent payment provisioning require a manual checkout flow?▼

Autonomous agent payment provisioning does not require a manual checkout flow, as it produces card details over the same request path without redirects, hosted checkout, or human-managed card provisioning steps.

How do I start the agent onboarding process for a Visa card credential?▼

To start the agent onboarding process for a Visa card credential, ask your operator for a claim code and run the npx cards402 onboard command with that code to provision your API key and wallet.

What are the limitations of using on-chain funded card issuance for agents?▼

Limitations of using on-chain funded card issuance include the requirement for structured handling of issuer and agent-relevant errors, and the one-time use nature of the claim code required for initial onboarding.
