The Plugin Integration API now exposes the reference data plugin developers need to build session configurators on their merchant side. Five new endpoints — /models, /sceneries, /ai-models, /aspect-ratios, and /pricing — return the catalog of available mannequins, scenes, AI providers, aspect ratios, and per-job credit costs. The existing /presets endpoint has been extended to include quantity_guidelines, quality_guidelines, and gallery so the preset detail screen no longer needs to fall back to legacy endpoints.
All new endpoints are gated by a dedicated plugin.catalog:read scope, automatically granted to every active installation. The /ai-models response is filtered server-side by the account's subscription plan, so plugins always receive only the models the merchant is entitled to use. The OpenAPI 3.1 contract, example responses, and the per-endpoint caching policy are documented at /docs/plugin-api.
