Quick Start

Get your first virtual Visa card issued in under 5 minutes. This guide walks through installation, initialization, and issuing a card.

Installation

npm install mppfinance

Initialize client

Create a client instance with your agentId and target network. Use testnet: true during development.

import { MPPFinance } from 'mppfinance'

const client = new MPPFinance({
  agentId: 'your-agent-id',
  network: 'solana',
  testnet: true,
})

Issue your first card

Call client.issue() with an amount, currency, and optional spending rules. The card is ready in under 300ms.

const card = await client.issue({
  amount: 50_00,        // $50.00
  currency: 'USD',
  rules: {
    merchant: 'aws.com',
    singleUse: true,
    expiresIn: 300,
  },
})

console.log(card.number)  // "4111 •••• •••• 9821"
console.log(card.cvv)     // "***"
console.log(card.expiry)  // "12/27"

Revoke a card

Revoke any card at any time. Once revoked, all further charges are declined instantly.

await client.revoke(card.id)
