Documentation

Ship your first asset in 5 minutes.

Everything is plain HTTPS. Upload, version, map to an environment, and fetch — no SDK to install, nothing to learn twice.

1
Upload an asset
POST any image, video, audio, PDF, or 3D model. It becomes version v1 automatically.
2
Map it to an environment
Point DEV, QA, or PROD at any version. Swap versions anytime — no rebuild, no redeploy.
3
Fetch it anywhere
One GET request from web, mobile, or your game engine returns the right version for that environment.
# 1 · upload
curl -X POST https://api.umbercloud.io/v1/assets \
-F "file=@hero-character.glb" -H "Authorization: Bearer $KEY"
# 2 · map v1 to prod
curl -X PUT https://api.umbercloud.io/v1/envs/prod/assets/hero-character \
-d '{"version":"v1","state":"active"}'
# 3 · fetch from anywhere
curl https://api.umbercloud.io/v1/assets/hero-character -H "X-Env: prod"
