# Preview LoRA Source Before Registration

`POST /v1/adapters/source-preview`

## Request

- Base URL: `https://api.hydracept.com`
- URL: `https://api.hydracept.com/v1/adapters/source-preview`
- Auth: HTTP bearer

Look up a public Hugging Face LoRA and propose registration choices.

The response fills revision, weights file, base-model family, name, strength,
and trigger words when the model card knows them. It does not register an
adapter, download weight tensors, or spend provider credits. Several equally
plausible weight files stay unselected until the caller chooses one.
