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.

Get YOUR x402 endpoint listed in this Bazaar - done for you, $99 one-time. You receive a deploy-ready x402 v2 kit generated for your stack (Next.js, Express, serverless; PHP via a free serverless function) with your wallet, price and discovery declaration baked in, plus a resumable listing_key that drives the automated pipeline via MCP (https://mudko.com/api/mcp): validate against Coinbase's own preflight with per-check fixes, and when your price is $1 or under WE fire the indexing settlement from our funded wallet.
