GLB is the saved visual file; glb_bundle is the saved ZIP with visual, collision, and physics files when available. Downloads do not regenerate outputs. Returns 409 export_not_available if the release did not produce this format. ## OpenAPI ````yaml /openapi.json get /v1/assets/{asset_id}/files/{format} openapi: 3.1.0 info: title: Gizmo Asset API description: >- Generate and export individual 3D assets from text and reference images. Export assets to USD / USDZ, MJCF, SDF, and GLB. Available formats depend on the asset and its accepted release. A successful export is not simulator certification. ## Authentication All endpoints require an API key passed via the `Authorization` header: ``` Authorization: Bearer gzm_k1_ ``` Select Personal or your Team in Gizmo, then create a key in API Access. Both use https://api.gizmo.antimlabs.com; the key selects the library and billing account. A Team may be called workspace in response fields and error codes. ## Rate Limiting Rate limits are per-key. Rate-limited API-key responses include: - `X-RateLimit-Limit` — requests allowed per minute - `X-RateLimit-Remaining` — requests remaining in current window - `X-RateLimit-Reset` — Unix timestamp when the window resets ## Async Generation Asset generation is asynchronous. `POST /v1/assets` returns `202 Accepted` with a `job_id`. Use `GET /v1/jobs/{id}` to poll. Personal keys also support `GET /v1/jobs/{id}/events` for SSE streaming. Team keys currently do not support SSE, GET /v1/usage or DELETE /v1/assets/{asset_id}; those operations return 403 workspace_route_unavailable. Use polling for progress and Team Billing for the current balance. Batch generation, saved-file links and export-only retries require Team access. One shared API reference describes both key types; it does not imply every operation is available to both. Team generation requires Idempotency-Key. ## Errors Errors on public endpoints use `detail.error` with code, message, and status. Validation errors also include fields. Responses include X-Request-ID for support. ```json {"detail": {"error": {"code": "asset_not_found", "message": "Asset not found", "status": 404}}} ``` version: 1.0.0 servers: - url: https://api.gizmo.antimlabs.com description: Production security: - ApiKeyAuth: [] tags: - name: Batches description: >- Team-only, asynchronous generation of up to 1,000 assets, with durable progress and partial results. - name: Images description: Upload and retrieve private original reference images. - name: Assets description: >- Manage individual 3D assets (articulated objects, furniture, equipment).
