Generate a video from a text prompt. Returns a request_id for status polling.

Prerequisite: Consult the Model Selection endpoint to identify a valid model slug and check specific limits (resolution, duration, framerate).

OpenAI SDK users: This endpoint is also available via the OpenAI-compatible surface as POST /v1/videos at https://oai.deapi.ai/v1. See OpenAI Compatibility.

Authorizations

Authorization

string

header

required

Sanctum personal access token, sent as Authorization: Bearer <token>. The token is opaque — it carries no claims and no embedded expiry, so do not attempt to decode it. Issue and revoke tokens from your account dashboard.

Headers

enum<string>

default:application/json

required

Available options:

application/json

Body

application/json

Text to video conversion parameters

Every example in this schema is a working set for the model example shown — they are not defaults and not portable. Sizes, step counts, frame counts and frame rates are all per-model: read info.limits and info.defaults for the model you actually intend to use from GET /api/v2/models. Substituting a different model while keeping these values is the most common source of a 422.

prompt

string

required

The main prompt for video generation

Example:

"A beautiful sunset over mountains"

width

integer

required

Width of the generated video in pixels. The accepted range is model-specific — read info.limits.min_width/max_width and min_height/max_height for your model from GET /api/v2/models. Some models also publish dimension_multiple or resolution_step: values are snapped DOWN to that grid before validation, so an off-grid size is silently reduced rather than rejected. max_pixels and max_ratio, where present, cap total area and aspect ratio on top of the per-side bounds.

Example:

512

height

integer

required

Height of the generated video in pixels. The accepted range is model-specific — read info.limits.min_width/max_width and min_height/max_height for your model from GET /api/v2/models. Some models also publish dimension_multiple or resolution_step: values are snapped DOWN to that grid before validation, so an off-grid size is silently reduced rather than rejected. max_pixels and max_ratio, where present, cap total area and aspect ratio on top of the per-side bounds.

Example:

512

frames

integer

required

Number of video frames to generate. The accepted range is model-specific — read info.limits.min_frames/max_frames for your model from GET /api/v2/models; a value outside it is rejected with 422.

Example:

120

fps

integer

required

FPS of the generated video. The model dictates the value: read info.defaults.fps for your model from GET /api/v2/models. Where min_fps equals max_fps that is the only accepted value; anything outside the range is rejected with 422.

Example:

30

seed

integer

required

Random seed for generation

Example:

42

model

string

required

The model to use for video generation. Available models can be retrieved via the GET /api/v2/models endpoint.

Example:

"Ltxv_13B_0_9_8_Distilled_FP8"

negative_prompt

string | null

Elements to avoid in the generated video

Example:

"blur, darkness, noise"

guidance

number

Guidance scale. Required only when the model declares info.features.supports_guidance; for a model that does not, the value is accepted and ignored. Bounds are info.limits.min_guidance / max_guidance, from GET /api/v2/models.

Example:

7.5

steps

integer

Number of inference steps. Required when the model publishes step bounds: send it if info.limits.min_steps / max_steps or info.defaults.steps is present for your model in GET /api/v2/models, and stay inside that range. Key off those fields rather than info.features.supports_steps, which some models omit while still using steps.

Example:

1

enhance_prompt

boolean

default:false

When true, the prompt is boosted by the inline prompt booster before generation (async pre-step). Requires a prompt-booster guide configured for the model; the boost fee is billed on the job. Rejected with 422 if no guide exists for the model or the account balance cannot cover the boost fee.

Example:

false

webhook_url

string<uri> | null

Optional HTTPS URL to receive webhook notifications for job status changes (processing, completed, failed). Must be HTTPS. Max 2048 characters. A per-request URL is self-contained: it is delivered even when the account has no webhook configuration, or the account webhook is disabled. See the webhooks block at the top level of this document for the event payloads and the headers each delivery carries.

Maximum string length: 2048

Example:

"https://your-server.com/webhooks/deapi"

webhook_secret

string | null

Optional per-request HMAC secret (min. 32 chars) used to sign the webhook callback. Overrides the account-default secret for this job only. If omitted, the account-default secret signs the callback; if no secret exists at all, the callback is still delivered but UNSIGNED (empty X-DeAPI-Signature header). Requires webhook_url to also be set.

Required string length: 32 - 255

Example:

"a1b2c3d4e5f60708091a2b3c4d5e6f7081920a1b2c3d4e5f60708091a2b3c4d5"
