Stablecoin Off-Ramp API for Developers

Convert USDC, EURC, and EURCV to EUR via SEPA Instant. Multi-chain, MiCA-compliant, and designed for both human developers and autonomous AI agents.

Building an app that handles stablecoins? At some point, you or your users need to convert those USDC tokens to actual euros in a bank account. That's what an off-ramp API does — and in 2026, it's easier than ever.

What Is a Stablecoin Off-Ramp?

An off-ramp converts crypto assets (in this case, stablecoins like USDC, EURC, or EURCV) into fiat currency (EUR) and deposits it to a bank account. The "API" part means you can integrate this conversion directly into your application without sending users to an exchange.

Why You Need an Off-Ramp API in 2026

• AI agent payments: Your agent earns USDC via x402 — you need those earnings in EUR
• Merchant acceptance: Accept crypto from customers, receive EUR in your business account
• Payroll and payouts: Convert stablecoin treasury to EUR for salaries and expenses
• DeFi exits: Move yield farming profits from on-chain to your bank
• Remittances: Send USDC internationally, recipient gets local EUR

AsterPay Off-Ramp API: Quick Start

Step 1: Get a Settlement Estimate

curl https://x402.asterpay.io/v1/settlement/estimate \
  -H "Content-Type: application/json" \
  -d '{
    "amount": "500",
    "currency": "USDC",
    "target": "EUR",
    "chain": "base"
  }'

Step 2: Python Integration

from asterpay import AsterPay

client = AsterPay()

# Get real-time estimate
estimate = client.settlement.estimate(
    amount="500",
    currency="USDC",
    target="EUR",
    chain="base"
)

print(f"Receive: €{estimate.estimated_eur}")
print(f"Fee: {estimate.fee_percent}")
print(f"Time: {estimate.settlement_time}")

Step 3: MCP Server (For AI Agents)

// claude_desktop_config.json
{
  "mcpServers": {
    "asterpay": {
      "command": "npx",
      "args": ["@asterpay/mcp-server"]
    }
  }
}

// Your AI agent can now call:
// - get-settlement-estimate
// - check-trust-score
// - get-market-price
// All via x402 micropayments
