Tripo 3D

Tripo (by VAST) turns text prompts and images into high-fidelity 3D models. All generation is asynchronous: you submit a task, receive a task_id, then poll the task until it finishes and download the result.

Official docs: https://platform.tripo3d.ai/docs/introduction

When to Use

Use this skill when you need to:

Generate a 3D model from a text prompt (text-to-3D)
Generate a 3D model from one image or multiple views (image-to-3D, multiview-to-3D)
Refine a draft model into a higher-quality version
Re-texture, stylize, convert (GLB/FBX/USDZ), animate, or post-process a model
Check the account balance (wallet)

Prerequisites

Connect the Tripo connector at app.vm0.ai/connectors.

The connector injects TRIPO_API_KEY (a tsk_-prefixed key) and authenticates every request with Authorization: Bearer $TRIPO_API_KEY.

Troubleshooting: If requests fail, run zero doctor check-connector --env-name TRIPO_API_KEY or zero doctor check-connector --url https://api.tripo3d.ai/v2/openapi/wallet --method GET

Base URL for all endpoints: https://api.tripo3d.ai/v2/openapi

How to Use

1. Text to 3D Model

Submit the task:

curl -s -X POST "https://api.tripo3d.ai/v2/openapi/task" --header "Content-Type: application/json" --header "Authorization: Bearer $TRIPO_API_KEY" -d '{"type": "text_to_model", "prompt": "a small cute robot, clean topology"}' | jq '.data.task_id'

The response shape is {"code": 0, "data": {"task_id": "..."}}. Take the task_id and poll it (see Polling below).

Useful optional fields: model_version (e.g. v2.5-20250123, v3.0-20250812), negative_prompt, texture (bool), pbr (bool), face_limit (int).

2. Image to 3D Model

First upload the image to get a file_token:

curl -s -X POST "https://api.tripo3d.ai/v2/openapi/upload/sts" --header "Authorization: Bearer $TRIPO_API_KEY" -F "file=@/tmp/input.png" | jq '.data.image_token'

Then submit the generation task with that token. Replace <image-token>:

curl -s -X POST "https://api.tripo3d.ai/v2/openapi/task" --header "Content-Type: application/json" --header "Authorization: Bearer $TRIPO_API_KEY" -d '{"type": "image_to_model", "file": {"type": "png", "file_token": "<image-token>"}}' | jq '.data.task_id'

file.type should match the image format (png, jpg, webp). Suggested resolution ≥ 256×256.

3. Multiview to 3D Model

Provide up to four orthographic views (front, left, back, right) as uploaded tokens. Use null for any view you do not have. Replace the <*-token> values:

curl -s -X POST "https://api.tripo3d.ai/v2/openapi/task" --header "Content-Type: application/json" --header "Authorization: Bearer $TRIPO_API_KEY" -d '{"type": "multiview_to_model", "files": [{"type": "png", "file_token": "<front-token>"}, {"type": "png", "file_token": "<left-token>"}, {"type": "png", "file_token": "<back-token>"}, {"type": "png", "file_token": "<right-token>"}]}' | jq '.data.task_id'

4. Polling a Task

Replace <task-id> with the task_id returned from any submit call:

curl -s "https://api.tripo3d.ai/v2/openapi/task/<task-id>" --header "Authorization: Bearer $TRIPO_API_KEY" | jq '{status: .data.status, progress: .data.progress, model: .data.output.pbr_model}'

status values: queued, running (ongoing) → success, failed, banned, expired, cancelled (finalized). Poll every few seconds until the status is finalized. On success, data.output holds the result URLs.

5. Download the Result

Important: output URLs (model, base_model, pbr_model, rendered_image, etc.) expire 5 minutes after the task succeeds. Download immediately once status is success. Replace <model-url>:

curl -s -L "<model-url>" -o /tmp/tripo_model.glb

6. Refine, Texture, Animate, Post-process

These are also tasks; chain them by passing the source task's id. Examples:

Refine a draft: {"type": "refine_model", "draft_model_task_id": "<task-id>"}
Texture: {"type": "texture_model", "original_model_task_id": "<task-id>", "texture": true, "pbr": true}
Animate (rig + retarget): {"type": "animate_rig", "original_model_task_id": "<task-id>"} then {"type": "animate_retarget", "original_model_task_id": "<rig-task-id>", "animation": "preset:walk"}
Convert / stylize (post-process): {"type": "convert_model", "original_model_task_id": "<task-id>", "format": "FBX"} (formats include GLTF, FBX, OBJ, STL, USDZ)

Submit each to POST /task and poll the same way.

7. Check Balance (Wallet)

curl -s "https://api.tripo3d.ai/v2/openapi/wallet" --header "Authorization: Bearer $TRIPO_API_KEY" | jq '.data'

Guidelines

Everything is async — every generation returns a task_id; always poll GET /task/{task_id} until status is finalized before reading output
Download fast — output URLs expire 5 minutes after success; persist the file immediately
Upload before image input — image_to_model / multiview_to_model need a file_token from POST /upload/sts (or POST /upload), not a raw URL
Pick a model version — omit model_version to use the default, or pin a version (e.g. v3.0-20250812) for reproducibility; newer versions support more parameters
Status failed / expired — retry and report the task_id to Tripo support if it recurs; banned means the prompt or image violated content policy
Cost — generation consumes account credits; check GET /wallet before large batches and top up in the Tripo billing dashboard
