Give the agent the product's 3D file (a GLB, glTF, FBX, USD or OBJ link, or a .blend) and ask for a turntable: on JANCTION Render that is one call, render_final(scene_url=..., orbit=True, orbit_frames=24, environment='studio', output='mp4'), and the agent gets back an MP4 of one full rotation with the camera framed on the object. A 24-frame 720p turntable of a headphones model took 58 GPU-seconds on the production GPU (about 6 JPY at the planned rate, free during the beta). Preview the first four angles first (render_preview with orbit=True), fix the lighting or the framing, then render the final. No Blender, no GPU and no account are needed on your side.
One MP4 (24 fps) of a full rotation around the product, lit by a studio HDRI, with the camera distance and elevation chosen automatically from the model's bounds. Options: orbit_frames 24 / 48 / 96 (smoothness), orbit_elevation in degrees (default 18), transparent=True for WebM / GIF / WebP with alpha, environment studio / sunset / overcast / night. The measured example: headphones, 24 frames, 1280x720, 64 samples, 58.3 GPU-seconds.
render_preview(scene_url=..., orbit=True, environment='studio'): four angles in one image in a few seconds. Say what to change (lighting preset, elevation, background).render_final(scene_url=..., orbit=True, orbit_frames=24, width=1280, height=720, environment='studio', output='mp4'). The agent reports the time estimate and returns a download link (valid 24 hours), or a share page you can send to the client.curl -s -X POST https://render.janction.jp/v1/keys # a key, no sign-up
curl -s -X POST https://render.janction.jp/v1/files/url -H "X-API-Key: $KEY" \
-H "Content-Type: application/json" -d '{"url": "https://example.com/headphones.glb"}' # -> scene_id
curl -s -X POST https://render.janction.jp/v1/outcomes/turntable -H "X-API-Key: $KEY" \
-H "Content-Type: application/json" -d '{"scene_id": "...", "size": "720p", "frames": 24, "environment": "studio"}'
# -> job_id and a fixed price (0 during the beta); then GET /v1/jobs/{job_id} until done and fetch output.mp4
POST /v1/outcomes/turntable is the fixed-price form of the same render (the price is stated before the job starts); POST /v1/jobs with orbit: true is the metered form. Both are in the OpenAPI.
| Good fit | Not this |
|---|---|
| catalog items as GLB / glTF / FBX / USD / OBJ; packshots for a product page; a batch of SKUs from a script | editing the model (use a modeling tool or a local Blender MCP first); photoreal cloth or fluid simulation |
| 24 to 96 frames, 720p or 1080p | 4K during the beta (1080p is the per-job limit) |
Textures referenced by a glTF or OBJ are fetched from the same folder as the file; FBX and USD should embed or ship their textures (pass extra files with asset_urls). Transparent background: transparent=True with output='webm' (or gif / webp); MP4 cannot carry alpha. See rendering 3D files and turntables from a .blend.

No. A GLB / glTF / FBX / USD / OBJ / STL / PLY link is imported into an empty scene, centred and framed. A .blend works too and keeps its own camera unless orbit=True.
Yes: POST /v1/outcomes/product-shot (0 / 90 / 180 / 270 degrees, PNG, optional transparent background), or cameras=[...] for named cameras in a .blend.
Measured: 24 frames at 720p, 64 samples, 58 GPU-seconds plus a few seconds of queue. 48 frames roughly doubles it. The agent tells you the estimate before it starts.
During the free beta the service is provided as is with no availability guarantee; you own your renders. Commercial-use terms come with the paid plans (see /pricing and /terms).
