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, supportsMultiView, supportsUltraMode, ultraCost, ... }] — use name as the engine/model value. NOTE: the two 3D surfaces are SEPARATE catalogs — 3d is text-to-3D, image-to-3d is image-to-3D. An unrecognized category silently falls back to 3d, so a guessed value returns a plausible list that is missing image-only engines.

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 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). Set count (1–4) for several images from one call: the top-level fields stay the first image and assets[] lists every image (same batchId) — wait_for_asset on each id. Each image is billed separately; if the balance can't cover all of them nothing is charged. A count above the plan's image slots fails with 400 (don't retry); a busy queue fails with 429 (retry later).

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 one image, or from 2–4 views of the same subject (multi-view → higher-fidelity geometry), async. Single: 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). Multi-view: image_urls OR image_paths, ordered [front, left, back, right] (2–4 views). Not every engine takes multi-view — check supportsMultiView from list_models(category='image-to-3d'); unsupported engines return 400. Local files win over URLs. Then wait_for_asset and read files.model. Costs credits — see list_models(category='image-to-3d') (NOT category='3d', which is the text-to-3D catalog and omits image-only engines).

Decompose one reference image into an exploded "parts board" image (async) — the subject laid out as separated components on one canvas. Input: asset_id (an existing IMAGE asset you own), image_url (a public http/https image), OR image_path (a local file, uploaded directly). Engine/resolution/prompt are server-fixed — no params. Returns an asset { id }; call wait_for_asset (or poll get_asset) until taskStatus=2 and read files.image (the board PNG). Feed that image to generate_3d_from_image for a parts-separated mesh. Costs 80 credits — see list_models(category='parts-board'). Precedence when several are set: image_path > asset_id > image_url.

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).
