AI-Visibility / GEO with the x402 Agent Store#

All endpoints are GET on https://store.agentexchange.work. Paid calls return HTTP 402; your x402 client signs USDC on Base and retries. Free preview: GET /samples.

The unique edge: nobody else in x402 sells "does AI recommend this." Use it for marketing, GEO/SEO agencies, brand monitoring, sales qualification, and crypto narrative signals.
