Endpoint
POSThttps://video.withzero.xyz/api/v1/videos/veo-3.1When to prefer
Choose this endpoint when maximum visual fidelity is the priority — specifically when 4K resolution or the highest-quality Google Veo 3.1 output is required. Prefer the Fast variant if speed matters more than quality, or Kling/Sora endpoints for different motion aesthetics. Best for cinematic, professional, or high-production-value video generation tasks.
Side effects
- Invalid or empty prompt returns 400 validation error
- Unsupported duration value (not 4, 6, or 8) returns schema validation error
- Unsupported resolution value returns enum validation error
- Job creation fails due to upstream Google Veo API outage — may return 502 or 503
- Polling the job ID may return 'failed' status if content policy is violated or generation errors out
- Timeout or long queue times at 4K resolution may result in extended pending state
