Integrations

Connect AsterPay in one line.

Drop AsterPay into any agent: an MCP server, a Python SDK, or a plain HTTP call. Free read endpoints (trust score, settlement estimate) need no signup and no API key.

Time to first paid call: under 10 minutes.

From $0.001/call · no minimums EUR in your bank in 10s Agent-native · KYA + ERC-8004 + x402/MPP

Your first call

Estimate a USDC to EUR settlement. No auth required for read endpoints. Pick your language.

# Free read endpoint, no API key — estimate 100 USDC → EUR
curl "https://x402.asterpay.io/v1/settlement/estimate?amount=100"

from asterpay import AsterPay

client = AsterPay()  # no key needed for read endpoints
quote = client.settlement.estimate(amount_usdc=100)
print(quote)  # netEurAmount, eurRate, fees, estimatedSepaTime

const res = await fetch(
  "https://x402.asterpay.io/v1/settlement/estimate?amount=100"
);
const { data } = await res.json();
console.log(data.netEurAmount, data.estimatedSepaTime);

// Add the AsterPay MCP server to any MCP-capable agent
{
  "mcpServers": {
    "asterpay": {
      "command": "npx",
      "args": ["-y", "@asterpay/mcp-server"],
      "env": { "ASTERPAY_BASE_URL": "https://x402.asterpay.io" }
    }
  }
}

Paid endpoints accept either x402 or MPP payment proofs on the same call. Same surface, two protocols.

Use it in your agent

The MCP server exposes AsterPay's commerce tools (settlement estimate, KYA trust score, market data, merchant discovery, agent payments) to any MCP client. No API key.

npx -y @asterpay/mcp-server

DeerFlow

ClawHub (OpenClaw) ships AsterPay as a bundled connector. DeerFlow agents get KYA trust score, merchant resolve, and USDC→EUR settlement estimate via the remote MCP server — source at github.com/AsterPay/deerflow-skill. Building a host yourself? Point any MCP stdio client at npx @asterpay/mcp-server.
