Florist bouquet photo to a 5-second Reel clip: Wan 3.0 at 480p vs 720p

A florist can turn a bouquet photo into a 5-second 9:16 clip with wan-3.0 for $0.3125 at 480p or $0.625 at 720p, so twelve bouquets a week cost $3.75 or $7.50. These are Sume prices: Wan 3.0 provider list of $0.05 and $0.10 per second times 1.25 (Video Router, read 2026-10-05).

What is the request for one bouquet?

Send the bouquet photo as first_frame and ask only for gentle motion, so the flowers stay the flowers you are selling.

curl -X POST https://api.sume.com/v1/videos \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"wan-3.0","prompt":"Soft window light, petals sway very slightly, camera drifts a few centimeters to the right","duration":5,"resolution":"480p","aspect_ratio":"9:16","frame_images":[{"type":"image_url","image_url":{"url":"https://example.com/bouquet.jpg"},"frame_type":"first_frame"}]}'

What does a weekly set cost?

Run every bouquet at 480p first, keep the clips that look right, and re-run only those at 720p. The table assumes all clips are re-run, which is the upper bound.

How do I poll and download the result?

A submit returns 202 with id, polling_url, status and model. Poll GET /v1/videos/{id} until status is completed (the other terminal values are failed and cancelled), then download from GET /v1/videos/{id}/content?index=0 with the same bearer key. Submit jobs one at a time, or send an Idempotency-Key header so a network retry returns the original job instead of a second one.

curl https://api.sume.com/v1/videos/JOB_ID -H "Authorization: Bearer $SUME_API_KEY"
curl -L "https://api.sume.com/v1/videos/JOB_ID/content?index=0" \
  -H "Authorization: Bearer $SUME_API_KEY" --output clip.mp4

What should the prompt avoid?

Avoid asking for new flower types, people holding the bouquet, or a text card. See the Wan 3.0 prompt guide for wording that describes motion and camera, not content.
