Crea una clave, llama a la API con autenticación Bearer y consulta el estado de la tarea hasta que tu resultado esté listo. Funciona con Claude Code, Codex y cualquier cliente HTTP.
Genera una clave de API en tu panel de control. Solo se muestra una vez, así que guárdala en un lugar seguro.
Envía una solicitud POST con tu clave Bearer y un encabezado Idempotency-Key.

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.

"message": "Invalid request body: prompt: String must contain at least 3 character(s)"

}| Código | HTTP | Significado |
|---|---|---|
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.
