GET/api/v1/models

List the avatar rendering models available for talking-avatar videos. Each entry reports its supported aspect ratios and resolutions and its maximum clip duration. Pass a model's model_id to POST /api/v1/video.

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)
modelsarray of ModelDtoRequired
Available avatar rendering models with their supported options.
Show 5 propertiesHide 5 properties
model_idstringRequired
Stable model identifier. Pass it as model_id when creating a video, e.g. vs_talk_v1 or vs_character_v4.
descriptionstringRequired
Human-readable summary of the model's strengths and intended use.
aspect_ratiosarray of stringOptional
Aspect ratios this model can render; pass one of these as aspect_ratio when creating a video.
resolutionsarray of stringOptional
Output resolutions this model supports; pass one of these as resolution. Higher resolutions cost more credits and take longer to render.
max_duration_secondsintegerRequired
Maximum length, in seconds, of a video this model can generate in one request.

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.
