Seedance 2.5 run logs show how to avoid paying twice

The method here is built around a specific quirk of the Higgsfield API: its estimate endpoint returned a flat $0.84 for a 5-second Kling 3.0 Pro clip, but for Seedance 2.5 it returned an explanation of the pricing formula instead of a number. The author therefore reproduced that formula as code, tokenizing on resolution, duration and 24 frames, and used the result to gate every request against a self-imposed $8 ceiling.

That same caution carries into the retry logic. Because a dropped connection can hide whether a job was actually accepted, the workflow writes a record before sending, attaches an Idempotency-Key, stores the returned request_id and status_url immediately, and treats "record but no receipt" as a case for checking status rather than re-sending. Status checks ran about every 20 seconds until the job moved from queued to in_progress to completed.

On quality, the 480p and 720p hand-drip clips moved much the same way, though 480p softened the steam and ceramic detail. The author suggests using 480p while checking motion direction and camera work, then re-generating at 720p once a cut is chosen — while noting that the same prompt does not guarantee the same motion, so a 480p take may not reproduce exactly.
