Tools (4)

`get_listing`read-only	Get full public details (including the long description) of one approved listing by its id (cm_...).
`get_my_listing_status`read-only	Check the review status (pending, approved, rejected) of one of the user's own listings. Requires their API key.
`search_listings`read-only	Search approved products on the Digital Underground Developer Marketplace (apps, AI tools, books, templates by independent makers). Returns summaries with links. Checkout happens on each maker's own site.
`submit_listing`	Submit the user's own product to the marketplace. Requires the creator's API key (duk_..., from the Creator dashboard -> API keys; never guess one). Free. Every submission is screened and waits for human owner approval; nothing is published automatically. Only submit real products the user owns, with accurate claims.
