Api Endpoint

Bazaar Keepalive (prepaid year)

Stay listed in this Bazaar: resources are delisted after ~30 days without a settled payment. $190 prepaid year, agent-payable (the card alternative is $19/mo at mudko.com/pricing): our funded wallet settles a small heartbeat to your endpoint twice a month - the USDC lands in YOUR payTo, so the heartbeat costs you nothing - we watch your merchant-feed entry weekly and alert + resurrect on any delisting. Requires an existing Bazaar Listing Package: pass the listing_key issued by https://mudko.com/api/x402/bazaar-listing.
