Everything on this page refers to seedance-2.5 — also written seedance2.5, seedance 2.5 or seedance-25 — served through the OpenAI-compatible APIMart gateway at https://api.apimart.ai/v1.

Pricing (observed, snapshot 2026-09-24)

Tier Price
1080P $0.3849
720P $0.216
480P $0.0961

Billed per unit, pay as you go, $1 minimum top-up, no subscription and no free quota. Every task response returns cost / credits_cost so the charge can be checked per call.

What that costs at scale

Volume Cost
100 $9.608
1000 $96.08

Linear at the observed rate, no volume discount assumed.

How to call it

export APIMART_API_KEY="<token>"
curl --request POST --url https://api.apimart.ai/v1/videos/generations \
  --header "Authorization: Bearer $APIMART_API_KEY" --header 'Content-Type: application/json' \
  --data '{"model":"seedance-2.5","prompt":"a modern cliffside villa at dusk, slow camera push","size":"16:9","n":1}'

Submit, keep the task_id, then poll GET /v1/tasks/{id} until completed. The response carries the image/video URL and the exact amount charged.

Troubleshooting the first call

Symptom Cause Fix
401 key missing or truncated re-copy from the console; header is Authorization: Bearer $APIMART_API_KEY
no balance account has no credit top up from $1 — there is no free tier on any model here
429 too many concurrent calls on one key back off, retry with the same Idempotency-Key
model not found wrong id or wrong tier field copy the exact id seedance-2.5 (alias seedance2.5) from the table above
task failed prompt filtered, or a reference URL expired resubmit with a new Idempotency-Key

FAQ

How is it billed? Per generated second, by resolution. Which resolutions? 1080P, 720P, 480P. Is this a relay? Yes — APIMart is a third-party gateway. Same OpenAI-compatible request shape, different billing and settlement from the vendor's direct API.
