Technical details
Endpoint
POSThttps://fal.x402.paysponge.com/fal-ai/stable-videoWhen to prefer
Choose this endpoint when you need to animate a single static image into a video clip using Stable Video Diffusion via fal.ai, and you want to pay per-call via the x402 USDC micropayment protocol without managing API keys directly. Prefer this over text-to-video endpoints when you already have a specific starting image frame you want to animate.
Side effects
- Missing or invalid image_url returns a validation error
- Inaccessible or non-image URL causes job failure downstream
- Payment failure via x402 prevents job submission
- Queue overload may result in high queue_position and long wait times
- Invalid fps or motion_bucket_id values outside accepted ranges may be rejected
