AsterPay — EUR Settlement for AI Agents

What it does

Gives your OpenClaw agent access to AsterPay's API — 16 endpoints for crypto market data, AI tools, and EUR settlement estimates. All endpoints use the x402 pay-per-call protocol (USDC on Base). Several endpoints are free.

How to use

AsterPay runs as an MCP server. Add it to your OpenClaw configuration:

Option 1: Via mcporter (recommended)

Tell your OpenClaw agent:

text

Install the AsterPay MCP server: npx -y @anthropic-ai/mcp-remote@latest https://x402-api-production-ba87.up.railway.app/mcp

Option 2: Manual config in clawdbot.json

Add to your clawdbot.json:

json

{
  "mcpServers": {
    "asterpay": {
      "command": "npx",
      "args": ["-y", "@anthropic-ai/mcp-remote@latest", "https://x402-api-production-ba87.up.railway.app/mcp"]
    }
  }
}

Option 3: Local MCP server

bash

npm install -g @asterpay/mcp-server

Then in clawdbot.json:

json

{
  "mcpServers": {
    "asterpay": {
      "command": "asterpay-mcp-server"
    }
  }
}

How x402 payments work

Paid endpoints return a 402 Payment Required response with payment details. To pay:

Install x402 fetch: npm install @x402/fetch
Configure a wallet with USDC on Base network
The SDK handles payment automatically per API call

Free endpoints (settlement_estimate, discover_endpoints, token tiers) work without any wallet.
