Offers one thing the caller's org owns on the marketplace — an agent, persona, app, skill or MCP server, or, for the platform, a tool sold per call — optionally monetized. The owning app is asked, as the org, whether the thing is the org's, so a listing never sells something that does not exist or belongs to someone else: a tool every org reaches is the platform's, and a server enabled off the public shelf is the shelf's. A monetized listing names a payout wallet of the org's own, which wallets confirms, so a price is never unpayable. The price is exact to 18 decimal places, so a per-call price below a cent is a real price and not a rounded-away zero. An org admin publishes, at most 1000 listings an org; it answers 201 with the created row.
