List available generation engines/models and their credit cost for a category. Call this before generating instead of hardcoding engine names. Returns [{ name, label, cost, paidOnly, ... }] — use name as the engine/model value.

List animation preset ids for the animate tool. Presets are engine-specific (Tripo ~97 / Meshy ~675) — pick one from the SAME engine you animate with. Optionally filter with a case-insensitive substring.

Get the current PicoBerry credit balance and plan for the authenticated key.

Generate a 2D image from a text prompt (async). Returns an asset { id }; then call wait_for_asset (or poll get_asset) until taskStatus=2 and read files.image (PNG URL). Costs credits — see list_models(category='image'). Omit model for the default. Up to 4 reference image URLs can guide the result (best with nano-banana).

Generate a game-ready 3D model (GLB) from a text prompt (async). Returns an asset { id }; call wait_for_asset (or poll get_asset) until taskStatus=2 and read files.model (GLB URL). Costs credits — see list_models(category='3d'). Omit engine for the default.

Generate a 3D model (GLB) from a single image (async). Provide EITHER image_url (any public http/https image, or a prior generation's files.image) OR image_path (a local file, uploaded directly — no hosting needed). Then wait_for_asset and read files.model. Costs credits — see list_models(category='3d').

Retopologize an existing 3D asset into a NEW asset (async). Costs credits — see list_models(category='remesh') (pb-remesh is cheapest). wait_for_asset → files.model.

Re-texture an existing 3D asset (PBR) into a NEW asset (async). Describe the desired look in prompt. Costs credits — see list_models(category='texture'). wait_for_asset → files.model.

Auto-rig an existing 3D character asset and apply an animation, producing a NEW asset (async). Pick preset from list_animation_presets for the SAME engine. Costs credits — see list_models(category='animate'). wait_for_asset → files.model.

Get a generation's status + result. taskStatus: 0=pending 1=processing 2=succeeded 3=failed. When succeeded, files.{model,image,thumbnail,textures} hold signed result URLs (short TTL — download promptly). On failure, read errorDetail.

Poll an asset until it finishes (taskStatus 2 or 3) or the timeout elapses, then return the final asset. Use right after generate_* / remesh / texture / animate. 3D generations can take several minutes.

List your generated assets (newest first, owner-scoped) for browsing/sync. Filter by category (3d/image/…) or keyword.

Export a completed 3D asset and get a short-lived signed download URL. glb = a single self-contained file. fbx/obj download as a .zip bundle (model + textures; + Unity .meta files when texture_preset='unity') — unzip before importing. For Unity use fbx (there is no built-in glb importer).
