api record

3dassets.dev is a free, open catalogue of web-optimised GLB models for three.js, Blender, Godot, Unity and any glTF-capable tool. Read tools need no auth. To submit assets on a user’s behalf you need their API key as a Bearer token: create_account → the user reads you the emailed code → verify_account returns the key. New submissions use CC0 1.0 Universal automatically. Before submitting, obtain the user’s acceptance of the CC0 dedication and their confirmation of publishing rights for the identified files or batch. No licence selection is needed. Retain licence metadata for historical…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_ai_models open 3h ago

    Search model suggestions from OpenRouter, refreshed hourly. Custom model/tool names are accepted; the list is not exhaustive. Unavailable suggestions never block uploads.

  • list_demos open 3h ago

    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.

  "type": "object",

  • get_demo unknown never probed

    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.

  • submit_asset_from_url unknown never probed

    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.

    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).

  • submit_pack unknown never probed

    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.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
