How this service works
Submit a video generation job to fal.ai. Charge is computed from the validated input. Preview the exact charge before paying via free `GET /price/:model?duration=…&resolution=…`. After submit, poll free `GET /status/:id` (or `HEAD /status/:id`) until the job completes — the response carries the final video URL. Per-model alias routes (POST /kling, POST /seedance, POST /veo3-fast, POST /veo3, POST /sora2, POST /wan, POST /hailuo) are equivalent entry points with the model preset.
Output
Returns a job object containing a unique job_id, a status_url to poll for completion, the model used, resolved inputs (duration, resolution, audio flag), a price breakdown showing cost_usd, markup_usd, and charge_usd in USDC, an estimated_seconds for completion, and a poll_interval_seconds recommendation.
Example use cases
Social media short clip creation
“Create a 5-second vertical video of a golden retriever playing in autumn leaves using the kling model — make it look cinematic and avoid anything blurry or out of focus.”
Image-to-video for product animation
“Turn this product image into a smooth 6-second video using the hailuo model: https://example.com/product.jpg — use 720p resolution and a widescreen aspect ratio.”
AI film scene generation with audio
“Generate a 8-second video of a futuristic city at night with neon lights and flying cars using veo3, enable the audio track, and output it in 1080p 16:9.”
Technical details
Endpoint
POSThttps://make-video.withzero.ai/run?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single unified entry point to submit video generation jobs across multiple top AI video models (Kling, Veo3, Sora2, Seedance, Wan, Hailuo) with transparent USDC pricing and a polling-based async workflow. Prefer this over per-model alias routes when your agent needs to dynamically select the model at runtime. Use after previewing the charge via GET /price to avoid surprise costs.
Side effects
- Invalid model slug — returns validation error if model is not one of the allowed enum values
- Missing required prompt — returns 400 if prompt is absent or empty
- image_url required but missing for image-to-video models (wan, hailuo) — returns validation error
- Duration or resolution not in per-model allow-list — returns preCheck rejection
- Prompt exceeds 2000 character limit — returns validation error
- Payment failure — charge cannot be processed in USDC
- fal.ai backend unavailable — upstream error propagated
