How this service works
Sub-second generative AI inference — image, video, audio.
Output

Example use cases
Example prompt

Technical details
Endpoint
POSThttps://fal.payweave.services/models/fal-ai/bytedance/seedream/v4/edit/runWhen to prefer
Choose this endpoint when you need to edit or transform an existing image using ByteDance's SeedDream v4 model with no subscription — paying only $0.06 USDC per call via x402. Prefer it over hosted fal.ai direct access when you want pay-per-call billing via crypto micropayments and don't have a fal.ai account.
Side effects
- Invalid or missing input image causes a 400-level error with a descriptive error string
- Model inference timeout returns an error status
- Unsupported edit instruction or out-of-distribution input may return a degraded or blank image
- Payment failure (insufficient USDC) results in a 402 response before inference begins
- CDN URL expiration (~24h TTL) makes the output inaccessible after the window
