johnalbertini14-glitch 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:
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:
{
"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
npm install -g @asterpay/mcp-server
Then in clawdbot.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.
