🌸 WDanbooru Injector

You see a post you like, and you want to riff on it - the pose, the framing, the style. If you're on Anima or any Danbooru-trained model, the honest way to do that is to reproduce the post's tag structure. Retyping forty tags by hand is miserable. This node fetches them for you: paste a booru post ID or URL, and it pulls the tags straight from the site's API, rebuilds them into a properly ordered prompt, and merges that into whatever you already had.

The name isn't a metaphor. It injects.

How it works

The WDanbooru Injector hits one of 13 sources - gelbooru, e621, danbooru, konachan.net, konachan.com, yande.re, lolibooru, safebooru, rule34, hypnohub, atfbooru, xbooru, or a fully offline manual mode - and fetches the post's tags. Where the API separates categories (e621 and Danbooru do), it splits tags into artist, character, copyright, and general; the flat boorus just dump everything into general. Then it assembles them in Anima's recommended order:

[quality] [year] [safety] [count] [character] [copyright] [@artist] [general]

Underscores become spaces, and artist tags get the @ prefix Anima wants. The whole point of that ordering is that the models you're using were trained on exactly this vocabulary - a correctly ordered tag string beats a sentence for control, and Anima's card spells this order out almost verbatim.

The inputs that matter

• source - which booru to fetch from.
• post_id - a plain number or the post's page URL. Don't paste the direct image URL; there's no post ID in it, and the node will tell you so.
• inject_mode - prepend (tags before your prompt), append (after), or replace (your prompt gets thrown away).
• safety_tag - the rating tag. Note the default is safe, so if your source post is explicit and you want that reflected, set it (or none).
• The four include toggles and max_general_tags (default 40) - trim the noise. Artist, character, and copyright toggles let you keep just the parts you want.

The optional inputs are where it gets useful: positive_prompt is your existing prompt to merge with, count_tag adds the character count (1girl, 2boys), extra_tags appends whatever you always want in there, and the gelbooru_user_id / gelbooru_api_key / e621_username / danbooru_api_key fields carry your credentials. The default quality prefix is masterpiece, best quality, score_7 - Anima's recommended opener. Score tags are the model's own quality dial, and if you're chasing a specific artist style you can drop the prefix entirely and let the @artist tag carry it.

Outputs

positive_prompt is the full merged string - wire it to your CLIP Text Encode positive input and you're done. injected_tags_only is the fetched block by itself, before your base prompt gets mixed in; it exists for debugging, and you'll be glad it does the first time a prompt comes out weird.

Installing it

ComfyUI Manager, search WDanbooru_Injector, install, restart. Manual, if that's your style:

cd ComfyUI/custom_nodes
git clone https://github.com/Winnougan/WDanbooru_Injector.git

Restart and you'll find it under WDanbooru. The only dependency is requests (already in ComfyUI), so no model downloads and no surprises.

Common gotchas

Gelbooru flat-out requires a free-account API key - every request, no exceptions - and the node raises a clear error telling you where to get it. e621 wants your username in its requests (their API policy), so fill e621_username or expect 403s. The node accepts credentials raw or with the key= prefixes stripped, so pasting the whole copied string works either way. And when all you want is no network at all - say, testing the tag ordering - switch source to manual and paste tags into manual_tags; no API call happens.
