Research API

Generate a prompt

Deterministic: the same query always returns the same JSON, which is why a generated prompt is shareable as a URL. This is the exact endpoint the generator page calls.

seed

Integer. The same seed with the same slots and pins reproduces a result exactly.

pins

Comma-separated tags always included, in order. Up to 50.

slots

Enabled slots as id:lo-hi, comma-separated. Omitted slots are disabled. Counts are capped at 5. Slot ids: count · character · copyright · artist · creature · composition · pose · action · expression · hair · eyes · attire · accessories · props · background · setting · lighting · style · quality

slotpins

Per-slot pins as id~name|name, comma-separated. They count toward that slot's target and are never dropped.

preview

A model family. Biases sampling toward tags that family already has pictures for. A nudge, never a filter — coverage records what has been uploaded, not what a model can draw.

lang

Adds a `localized` field to each tag, carrying its name in that language. `zh-CN` or `ja`; anything else is ignored. The prompt itself stays in canonical Danbooru names.

curl "https://tags.latent.moe/api/generate\
?seed=123\
&pins=1girl,hatsune_miku\
&slots=composition:1-1,pose:1-2,expression:1-1,attire:1-3\
&slotpins=attire~school_uniform|gloves,pose~sitting"

Returns seed, entries (each tag with its category) and slotOf, which maps every tag back to the slot that produced it — that is what lets a client group the output the way this site does.

Other endpoints

Danbooru tag autocomplete, optionally filtered by category and localized.

POST /api/v1/prompts/lint

Prompt diagnostics: unknown, deprecated and conflicting tags.

GET /api/v1/groups

GET /api/v1/coverage
