Seven tools

  • search_models — keyword search over title, tags and categories, with face-count filters and pagination.
  • get_model — full metadata for one model, including whether it is downloadable.
  • get_model_preview — returns a model's preview image, so your agent can confirm it has the right model before spending a credit.
  • download_model — returns a signed URL valid for 7 days. Consumes one credit.
  • generate_model — makes a new 3D model from one photo of an object. Asynchronous: it returns a task id straight away and the work takes 3–7 minutes. Consumes 6 credits, and the result is private to your account.
  • get_generation — reports one generation task. Once it finishes you get a download URL valid for 7 days; if it fails, the credits are refunded automatically.
  • list_generations — lists the generation tasks your account has run, newest first, so a model is still reachable after its task id is lost.

Searching and viewing a preview share one allowance: 2,000 reads per day and 30 per minute. A preview costs one read and one of the per-minute slots, the same as a search.

One shared balance

A credit bought here is the same credit as in Discord. Both storefronts sell the same seven products and spend from one balance, so nothing is stranded on the wrong side.
