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. ## Request 10 fields, body `application/json` (required). | Field | In | Type | Required | Description | | ------------- | ---- | ------- | -------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `category` | body | string | — | Category groups the listing in the shop window. | | `currency` | body | string | — | Currency denominates Price. | | `description` | body | string | — | Description is the long copy, at most 4096 characters. | | `docs` | body | string | — | Docs is where the listing's documentation lives: an https URL or a path on docs.hanzo.ai. | | `kind` | body | string | — | Kind is what is sold: agent, persona, app, skill, mcp or tool (the default). | | `price` | body | string | — | Price is the price as a decimal USD string, exact to 18 places — per call for a tool, what a job is offered at otherwise. | | `public` | body | boolean | — | Public makes the listing discoverable by other orgs. | | `recipient` | body | string | — | Recipient is the seller's payout wallet id, in the publishing org — the wallet x402 pays. | | `title` | body | string | — | Title is the shop-window name, 1-200 characters. | | `tool` | body | string | — | Tool names the thing sold, in the seller's own org: an agent's name or id, an app's project slug or id, a skill's name or id, an MCP server's name or id registered by hand, or a platform tool's registry name. | ## Response | Status | Body | Meaning | | --------- | ------------------- | ------- | | `201` | marketplace.Listing | created | | `default` | problem-details | refused | `201` body — 15 fields. | Field | In | Type | Always | Description | | -------------- | ---- | --------------- | ------ | ---------------------------------------------------------------------------------------------------------------------------------------- | | `category` | body | string | — | Category groups the listing in the shop window. | | `createdAt` | body | integer (int64) | — | CreatedAt is when the listing was published, in Unix SECONDS, minted at insert. | | `currency` | body | string | — | Currency is the ISO 4217 code Price is quoted in;
