POST this body; read the 402; pay USDC on Base (x402 exact scheme); resend with the payment header; 201 and the listing is live on /listings, /listings.json and every store discovery file. Paying again with the same url renews it.

curl -X POST https://bazaar.agentexchange.work/listings -H 'content-type: application/json' -d '{"url":"https://x402-api-production-266e.up.railway.app/","name":"x402-api-production-266e.up.railway.app"}'

Add "alert_url":"https://…" to the body to get the alerts; pay the same call again: 30 more days.
