Choose this endpoint when you need high-resolution (2K) AI-based image editing using ByteDance's Seedream v4 model, accessed via a pay-per-call x402 micropayment flow without requiring a subscription. Ideal for agents that need on-demand image transformation with per-call billing in USDC.
Side effects
- Invalid or missing input image causes a 400 error or null output
- Payment failure (insufficient USDC balance) returns 402 before inference begins
- Model-side error returns a non-null 'error' field with a description
- Output CDN URL expires after ~24 hours making the image inaccessible
- Unsupported image format or oversized input may result in inference failure
- Rate limiting or overload on fal.ai backend returns a timeout or error status
