Integration

MCP (Recommended)

One command installs dispute tools directly into your AI agent. No code changes required. Your agent automatically gets access to capture_intent, file_dispute, check_dispute, and more.

copyshellnpx @lu71/install --key=lu71_live_YOUR_KEY

Supports Claude Desktop, Claude Code, Cursor, Kiro, Windsurf, VS Code Copilot, ChatGPT Desktop, Codex CLI, Amazon Q, Cline, and Roo Code.

TypeScript SDK

Two function calls to integrate. Install the package, initialize with your API key, and call captureIntent before purchases and fileDispute when things go wrong.

copyshellnpm install @lu71/sdk

copytypescriptimport { Lu71 } from "@lu71/sdk"

const lu71 = new Lu71({ apiKey: "lu71_live_..." })

// Before purchase
const { intentId, signature } = await lu71.captureIntent({
  description: "Annual Pro plan for DataAPI.io",
  merchant: "DataAPI",
  maxAmount: 12000,
  currency: "gbp",
})

// If purchase goes wrong
const dispute = await lu71.fileDispute({
  intentId,
  intentSignature: signature,
  transactionId: "ipi_abc123",
  reason: "service_not_rendered",
  description: "Paid for Pro plan but account still shows free tier after 72 hours.",
})

REST API

Call directly from any language. All endpoints accept JSON and authenticate via the x-api-key header. Full reference in the docs.

copyshellcurl -X POST https://api.getlu71.com/v1/intents \
  -H "x-api-key: lu71_live_..." \
  -H "Content-Type: application/json" \
  -d '{"description": "Buy 50 widgets", "maxAmount": 5000}'

Supported Platforms
