create_account
Create account
Create a contributor account for the user. Needs only a username and email. There is no password anywhere in this product, so never ask the user for one. A 6-digit code is emailed to them; ask the user to read it to you, then call verify_account to receive their API key. Only do this with the user’s explicit consent.

get_demo
Get a walkable pack demo layout
Get one demo: the pack, the spawn point, the walkable bounds, the points of interest, and every placement (public asset slug, position in metres, yaw in degrees) with the CDN URL and bounds of each model placed. Load the models with a plain GLTFLoader and apply the transforms to reproduce the scene.

list_ai_models

List the walkable demo scenes staff have built from single packs. Each is a small environment a person can walk through on the site and an agent can load as a layout. Use get_demo for the placements.

my_assets
My assets
List the user’s submissions with status (processing, pending review, published, rejected + reason, failed + reason). `pendingEdit` means the user has metadata changes waiting for review; the published version is unchanged until they are approved.

search_assets
Search assets
Search the free GLB catalogue on 3dassets.dev (three.js, Blender, Godot, Unity) by text, category (what it is), theme (what world) and style (what look). Returns direct CDN URLs (CORS *, immutable) that load with a plain GLTFLoader. Published models use CC0 1.0 Universal: free personal and commercial use without attribution. Licence metadata is retained in each result.

submit_asset_from_url
Submit asset from URL
Submit a .glb hosted at a public https URL on the user’s behalf (requires their API key). We download it, validate and re-encode it, then a human reviews it before publishing. CC0 is automatic, but the user must accept its irrevocable dedication before submission. Max 25 MB, 1M triangles, embedded textures only.

submit_pack
Propose a pack
Group 2–50 of the user’s own uploads (any that are processing, pending or published) into a pack proposal. Upload the models first with finalize_upload or submit_asset_from_url, then pass their slugs here. Each model is still reviewed on its own; a person approves the pack as a whole, which publishes any members still pending and creates the pack page. Nothing goes live until then. The user is emailed the outcome.

update_asset
Update asset
Edit the metadata of one of the user’s own assets. The uploaded GLB can never be changed. Editing an asset that is already published does not change it: the proposal goes to the review queue and the live version keeps serving until a person approves it.
