title: CharGen Partner Account & catalog API
description: 'Wholesale generation API for images, video, audio, 3D models and structured D&D entities. Authenticate every call with `Authorization: Bearer YOUR_API_KEY` (keys are minted in the developer portal at char-gen.com/developers). Generations are asynchronous: POST returns 202 with an id, poll GET /partner/v1/generations/{id} for status and results (renders on POST /partner/v1/generations, structured D&D entities on POST /partner/v1/entities). Billing is a prepaid USD wallet; GET /partner/v1/models lists your per-model prices.'
