AI Video/Estimate cost

Estimate cost

GET/api/v1/ai_video/cost

Estimate the credits a generation will cost before submitting, using the same formula as the actual charge. Omit resolution to price the model default.

Beta: available to allowlisted API keys; standard per-key rate limits apply.

Query parameters

model_idstringRequired

Model to price for. Use an id from GET /api/v1/ai_video/models, e.g. seedance-2.0.

duration_secintegerRequired

Clip length in seconds to price. Must be an allowed value for the model (see GET /api/v1/ai_video/models).

resolutionstring | nullOptional

Output resolution to price, e.g. 720p / 1080p. Allowed values vary by model; omit to use the model default.

generate_audioboolean | nullOptional

Whether the estimate should include a native audio track. Omit to use the model default.

Headers

X-API-KeystringRequired

Your VisionStory API key (sk-vs-...), kept server-side. Create one at OpenApi (Pro plan and up).

Response

200Successful Response

Successful calls return a standard envelope: the endpoint payload under data (its fields are documented below), plus a message string ("success") and an ISO 8601 server_time.

Response fields (data)

creditintegerRequired

Estimated credits the generation will cost with the given parameters. Uses the same formula as the actual charge.

Errors

All error responses share one JSON envelope: an error object with a numeric code, a human-readable message, an optional details string, and an optional hint giving an actionable next step (handy for AI agents).

errorErrorDetailRequired

Error payload returned with every non-2xx response. Present only on failure; successful calls use the standard success envelope instead.

Show 4 propertiesHide 4 properties

codeintegerRequired

Machine-readable error code. Mirrors the HTTP status for transport-level failures (e.g. 401, 404, 422, 500) and may carry a business-specific code otherwise.

messagestringRequired

Human-readable explanation of what went wrong. Safe to log or surface to end users; not localized.

detailsstring | nullOptional

Optional structured detail about the failure, e.g. a JSON string of per-field validation errors on a 422. Absent when there is nothing extra to report.

hintstring | nullOptional

Actionable next step for resolving the error, written for both humans and AI agents (e.g. how to fix the request, or where to obtain an API key). May be absent.
