x402 Agent Store — pay-per-call data tools for AI agents
No API keys. No accounts. No subscriptions. Your agent calls a tool, pays a few cents in USDC over the x402 protocol, and gets live data back. That's it.
Works in Claude Desktop, Cursor, and any MCP client. Also discoverable by autonomous agents on the Coinbase x402 Bazaar.
The one thing nobody else sells: Does ChatGPT / Perplexity / Google AI actually recommend your brand (or token) when buyers ask? We turn that into a number an agent can buy.
Install (one step)
Claude Desktop → Settings → Connectors → Add custom connector:
https://store.agentexchange.work/mcp
Cursor → add to .cursor/mcp.json:
{
"mcpServers": {
"x402-agent-store": { "url": "https://store.agentexchange.work/mcp" }
}
}
Any MCP client (stdio bridge):
npx mcp-remote https://store.agentexchange.work/mcp
Free discovery first — no payment needed to look:
- Catalog: https://store.agentexchange.work/
- Free samples of every product: https://store.agentexchange.work/samples
- MCP manifest: https://store.agentexchange.work/.well-known/mcp.json

How paying works (x402, in 3 lines)
- Your agent calls a paid tool. It gets back HTTP 402 with exact payment requirements (price, recipient, network).
- It signs an EIP-3009 USDC authorization on Base (eip155:8453).
- It retries with the signed payload. Data comes back. No account, no key, no invoice.
Most MCP/x402 clients (e.g. @x402/mcp, @x402/fetch) handle this loop automatically — you just call the tool.
Minimal quickstart
See examples/quickstart.mjs for a ~20-line agent that discovers a tool and completes a paid call.
Why this exists
The agent economy runs on machine-to-machine micropayments. Agents need data they can buy without a human signing up for an API plan. This store is built for that: every tool is one call, priced in cents, settled per request. The flagship product — AI visibility — is data that doesn't exist anywhere else in agent-callable form: a measurement of whether large language models recommend a given brand or token to the people asking them for advice.
