After your fix, re-check every route now: GET https://bazaar.agentexchange.work/seller/preview-chat-985505b1-9dc0-470f-9fc3-3704d8b625e3.space-z.ai/report.json, 0.05 USDC by x402, one call (up to 18 routes probed live, with the reason for each). One route: GET https://bazaar.agentexchange.work/r/<id>/probe.json, 0.01. Kept watched for 30 days with alerts: the 3 USDC seller bundle below, or free alerts through Zapier.
Promote preview-chat-985505b1-9dc0-470f-9fc3-3704d8b625e3.space-z.ai on bazaar.agentexchange.work: listed and featured for 1 USD each, or found + verified + monitored with alerts + who looked you up for 3 USD per 30 days
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://preview-chat-985505b1-9dc0-470f-9fc3-3704d8b625e3.space-z.ai/","name":"preview-chat-985505b1-9dc0-470f-9fc3-3704d8b625e3.space-z.ai"}'Or the seller bundle: 3 USD for 30 days, renewable in one call
- Found: listed on /listings, /listings.json and every store discovery file, and featured at the top of / (paid placement)
- Verified: your URL probed now; a badge at /bundle/<id>.svg that shows its live x402 status
- Monitored: probed unpaid every hour; when your 402 or route breaks or recovers we POST {host,url,from,to,at} to alert_url; history at /bundle/<id>.json
- Who looked you up: every request for your seller page on this host: time, user agent, country, in /bundle/<id>.json
curl -X POST https://bazaar.agentexchange.work/bundle -H 'content-type: application/json' -d '{"url":"https://preview-chat-985505b1-9dc0-470f-9fc3-3704d8b625e3.space-z.ai/","name":"preview-chat-985505b1-9dc0-470f-9fc3-3704d8b625e3.space-z.ai"}'Add "alert_url":"https://…" to the body to get the alerts; pay the same call again: 30 more days.
Then POST https://bazaar.agentexchange.work/featured (1 USD, 30 days) puts it at the top of the front page.
