1. Get started

Use RunComfy's API to run vidu/q2/text-to-image. For accepted inputs and outputs, see the model's schema.

curl --request POST \
  --url https://model-api.runcomfy.net/v1/models/vidu/q2/text-to-image \
  --header "Content-Type: application/json" \
  --header "Authorization: Bearer <token>" \
  --data '{
    "prompt": "A minimalistic, rustic wall calendar for the month of December made of beige linen fabric with frayed edges, hanging on a textured gray wall. The calendar features black printed dates and days of the week in a simple serif font, with “December�?elegantly written in cursive at the top. It is clipped with a small silver metal binder clip and suspended by a rough jute string. The lighting is soft and warm, highlighting the natural fabric texture and subtle shadows. Style: cozy vintage home decor, natural materials, minimal composition, soft neutral tones, 8k detailed still life photography."
  }'

4. File inputs

Hosted file (URL)

Provide a publicly reachable HTTPS URL. Ensure the host allows server‑side fetches (no login/cookies required) and isn't rate‑limited or blocking bots. Recommended limits: images ≤ 50 MB (~4K), videos ≤ 100 MB (~2–5 min @ 720p). Prefer stable or pre‑signed URLs for private assets.
