doneRead endpoints for building a task history, showing remaining credits, or discovering models at runtime. They share the read rate limit.
/api/v1/tasksReturns the tasks this account created through the API in the last 30 days, newest first. Each item has the same shape as a single task. Use limit (1 to 50, default 20) and pass next_cursor as before to fetch the next page.

],
"has_more": false,

}/api/v1/balanceReturns the credits the key owner can spend through the API. subscription_credits is the part that came from a plan and expires at subscription_credits_expire_at.

"subscription_credits_expire_at": "2026-07-01T00:00:00.000Z"
}/api/v1/modelsReturns every model the API serves with its endpoint, accepted modes and task ID prefix. Useful for building a model picker without hard-coding this page.
curl "https://www.seedance2ai.io/api/v1/models" \
-H "Authorization: Bearer $SEEDANCE_API_KEY"{
"data": [
{

}Every error has the same shape. Branch on code, and show message to a person. A task that was accepted can still fail later, so also check status when you poll.

"error": {
"code": "invalid_request",
"message": "Invalid request body: prompt: String must contain at least 3 character(s)"
}
}| 코드 | HTTP | 의미 |
|---|---|---|
unauthorized | 401 | Missing, invalid, or revoked API key. |
invalid_request | 400 | Bad input or unsupported field. The message names the first field that failed; details lists them all. |
purchase_required | 403 | Seedance 2.5 requires a successful credits or plan purchase; free promotional credits alone do not unlock it. The GPT Image 2.5 economy channel has the same requirement. |
insufficient_credits | 402 | Not enough credits. Seedance 2.5 always returns HTTP 402 with insufficient_credits; when an authoritative quote is available, it may also include required_credits, available_credits, pricing_version, and promotion_applied. |
rate_limited | 429 | Too many requests for this account. See Rate limits below. Seedance requests that validate reference media are limited to 3 per 60 seconds per account and source IP, with a project-wide safety cap. Retry after the Retry-After response header (in seconds). |
idempotency_conflict | 409 | Same Idempotency-Key reused with a different body, or still running. |
service_busy | 503 | Temporary upstream or credit-concurrency issue. Retry. |
not_found | 404 | Task does not exist or does not belong to this key owner. |
internal_error | 500 | Unexpected server-side failure. |
A request over the limit returns HTTP 429 with a Retry-After header in seconds, plus X-RateLimit-Limit and X-RateLimit-Reset. Wait that long, then retry with the same Idempotency-Key.
