Method	`POST`
Operation	`post_marketplace_listings`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Publish offers one tool on the marketplace, optionally monetized. The tool must already resolve in the publisher's own scope, so a listing can never advertise a capability that does not exist; a listing with a price must name the payout wallet the x402 seam settles to, so a monetized offer 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. The listing is owned by the publishing org, paid into a wallet of that same org, and answers 201 with the created row.

Request

8 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, clipped at 4096 characters.
`price`	body	string	—	Price is the per-call price as a decimal USD string, exact to 18 places — "0.0025" is a quarter of a cent and stays one.
`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 is the registry name of the capability being offered.

Response

Status	Body	Meaning
`201`	Listing	created

201 body — 11 fields.

Field	In	Type	Always	Description
`category`	body	string	—	Category groups the listing in the shop window.
`createdAt`	body	integer	—	CreatedAt is when the listing was published, in Unix SECONDS, minted at insert.

`description`	body	string	—	Description is the long copy.
`id`	body	string	—	ID is the listing's id, minted here as "lst_" + 16 hex characters. A publisher cannot choose it: Create overwrites whatever arrives.

`public`	body	boolean	—	Public is whether other orgs can discover the listing.
`publisherOrg`	body	string	—	PublisherOrg is the org that published the listing, taken from the validated principal and never off the wire.

The door reaches marketplace through the marketplace tool, which names its 6 operations with its own verbs — this one among them, under a name only the door declares. describe explains any of them:

curl -X POST https://api.hanzo.ai/v1/mcp \

  -d '{
       "jsonrpc": "2.0",
       "id": 1,
