​
Datasets

Upload, manage, and query synthetic training datasets. Lucitra accepts data in COCO, KITTI, nuScenes, or custom formats and stores it on Google Cloud Storage with signed upload URLs.

​
Supported Formats

COCO

Object detection, instance segmentation, and keypoints. The most common format for 2D vision tasks.

KITTI

3D bounding boxes, point clouds, and stereo pairs. Standard for autonomous driving benchmarks.

nuScenes

Multi-sensor, multi-frame sequences with ego pose. Designed for full autonomous driving stacks.

Custom

Bring your own annotation schema. Define a format adapter and Lucitra handles the rest.

​
Create a Dataset

Creating a dataset returns a time-limited signed URL for uploading your data file directly to cloud storage.
1

Create the dataset record

Send a POST request with your project ID, dataset name, format, and optional metadata.
curl -X POST https://api.lucitra.io/v1/datasets \
  -H "Authorization: Bearer luci_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "project_id": "proj_abc123",
    "name": "warehouse-v3",
    "format": "coco",
    "metadata": {
      "simulator": "isaac-sim",
      "version": "4.5.0",
      "scene_count": 5000
    }
  }'

  "id": "ds_7kx9m2",
  "upload_url": "https://storage.googleapis.com/lucitra-datasets/...",
  "expires_at": "2026-03-06T13:00:00Z"
}
​
id
string
required
Unique dataset identifier. Use this in validation and report endpoints.
​
upload_url
string
required
Pre-signed GCS URL for uploading your data file. Valid for 1 hour.
​
expires_at
string
required
ISO 8601 timestamp when the upload URL expires.

Upload your data file

Use the signed URL from the response to upload your dataset archive via a PUT request.
curl -X PUT "${UPLOAD_URL}" \
  -H "Content-Type: application/octet-stream" \
  --data-binary @warehouse-v3.tar.gz
The upload URL expires after 1 hour. If it expires before your upload completes, create a new dataset to get a fresh URL.
