How to hit the Civitai API

Civitai's public REST API at https://civitai.com/api/v1 searches the community's image-generation models (checkpoints, LoRAs) and images. Reading needs no key.

Authentication

None for searching. A key from your Civitai account settings, sent as Authorization: Bearer <key>, is needed for some downloads and for NSFW content settings.
