Capabilities

Tools 18

create_space

Creates a space for one capture. An account that does not pay for hosting yet gets its first space as a free private preview: upload and process it with no payment. After that, it returns a Stripe Checkout link for the plan the person chose (pay as you go when none is given) for them to pay; then call wait_for_payment. Never ask for card details.

Discovered
create_tour

Starts a private guided tour or scavenger hunt on a space from find_tour_spaces; fill it with draft_tour or save_tour.

Discovered
draft_tour

Asks the site's tour agent, which sees the space's photographs, to write or rework the tour from a plain request: stops and text, hidden objects and clues, library models, effects, sound, music, looks with transitions and skies (day, sunset, storm, night, stars). It places everything and saves. Returns at once; then call wait_for_tour.

Discovered
find_tour_spaces

Spaces a guided tour or scavenger hunt can be built on: the person's own finished spaces and the site's public spaces (museums, temples, tombs, gardens). Search by words in the title.

Discovered
finish_upload

Checks that every uploaded file is complete and submits the space for processing. The account is emailed when the space is ready.

Discovered
get_tour

The tour as JSON (stops, objects, effects, looks, skies) with its revision, for editing with save_tour.

Discovered
link_account

Links this agent to the person's account. Returns a link where the person signs in and approves a short code; call again once they have. Never ask for a password.

Discovered
list_plans

The ways to pay for hosting, with prices, and the account's current plan. The first space is a free private preview, so show them when the person wants to publish it or keep it.

Discovered
list_tours

The tours and scavenger hunts on the account, with their links.

Discovered
save_tour

Saves a tour edited by hand: the experience JSON from get_tour with changes. Models use a url from search_models, or any https address of a .glb.

Discovered
search_models

Searches the library of ready-made 3D models (statues, amphorae, temples, furniture, animals, props from many periods). Returns each model's size and url.

Discovered
set_visibility

Makes a ready space public (anyone with the link) or private (only the owner). Ask the person first. A free preview cannot be public until hosting starts, so it returns a Stripe Checkout link for the person to pay.

Discovered
share_tour

Makes a tour public (anyone with its link, never listed) or private, and optionally renames it. Ask the person first.

Discovered
space_status

Status of one space, or every space on the account with its link when ready.

Discovered
unlink_account

Unlinks this agent from the account.

Discovered
upload_files

Starts resumable uploads for capture files you hold (for example photos or video the person shared with you) and returns where to PUT each file's bytes. For files on the person's own device, give them the space's page to drop the files instead.

Discovered
wait_for_payment

Waits up to 25 seconds for the person to finish paying in Stripe Checkout, whether for a space's first payment or to publish a free preview. Call it again to keep waiting.

Discovered
wait_for_tour

Waits up to 25 seconds for a draft to finish, then summarizes the tour. Call it again to keep waiting.
