Seedance 2.5 Fast API

Seedance 2.5 on dedicated, faster compute: your renders start straight away on capacity kept for this model instead of queueing behind shared traffic, so each video comes back sooner and large batches run side by side. 480p, 720p and 1080p, up to 30 seconds with sound, reference images and audio, and first and last frames.

Solicitud

# One Idempotency-Key per request, made once and sent again with every resend of it
KEY=$(uuidgen)

# 1. Submit. max_cost_usd is your cap: the most this may cost (it lists at $0.98).
#    No id after a timeout, a 429 or a 5xx? Run step 1 again: the same $KEY never makes a second one.
RESP=$(curl -s https://api.revana.si/v1/generations \

# 2. Poll it until status is "succeeded" or "failed". A failed one is free; to try it again,
#    make a new key first (KEY=$(uuidgen)): the old one answers with the failure.
