How to use /tacapi/v1/thumb-preview-blob/{filename} to get the preview?

[jandrop]

Hi,
When using the API to make requests, I'm facing a problem: I don't know the type to specify for a checkpoint. For getting the LoRA image, the type is set to "lora," but for the checkpoint, I'm unsure what to use.

[w-e-w]

that api is from a1111-sd-webui-tagcomplete
it simply dose not support getting preview of preview checkpoint
see code https://github.com/DominikDoom/a1111-sd-webui-tagcomplete/blob/08b7c58ea72774244c940d86f676f32a168f83d0/scripts/tag_autocomplete_helper.py#L777-L795

I think you will have more luck with the built-in api
/sd_extra_networks/thumb this is the api that used for extranetworks tab /sd_extra_networks/cover-images`
note this two api is only usable when webui are is available and not in API exclusive (--nowebui) mode

if you need more flexibility than I suggest you wrote a simple extension that adds an API endpoint that suits you exact needs
