API On-Demand & Commitment Tiers
FASHN API uses simple, credit-based pricing. You can start with on-demand credits and, when you're ready, add a monthly commitment tier to unlock included monthly credits and discounted top-up rates. All billing and usage are managed in the app's Developer API dashboard.

Credit Costs
Credit costs depend on the endpoint, resolution, and generation mode you select. Pricing is charged per successful output. Failed predictions do not consume credits.
Image Generation Endpoints
These costs apply to Product-to-Model, Model Creation, Model Swap, Face to Model, Edit, Reframe, and Try-On Max:
| Generation Mode | 1K | 2K | 4K |
|---|---|---|---|
| Fast | 1 | 2 | 3 |
| Balanced | 2 | 3 | 4 |
| Quality | 3 | 4 | 5 |
If you do not select a generation mode, the system selects one automatically based on factors like the requested resolution and endpoint. Available generation modes vary by endpoint; see each endpoint's documentation for details.
Additional pricing rules:
- Face Reference: +3 credits per output image (available on Product-to-Model, Model Creation, Model Swap)
- Multiple outputs: the per-output cost is multiplied by the number of images requested
Fixed-Cost Endpoints
| Endpoint | Credits per output |
|---|---|
| Virtual Try-On (v1.6) | 1 |
| Background Remove | 1 |
Video Generation
| Duration \ Resolution | 480p | 720p | 1080p |
|---|---|---|---|
| 5 seconds | 1 | 3 | 6 |
| 10 seconds | 2 | 6 | 12 |
Commitment Tiers (Subscription)
Commitment tiers include a monthly credit allowance and unlock discounted top-up rates. The included credits are a starting point, not a cap. You can top up additional credits at any time and they will be charged at the same discounted rate as your tier.
The same credit costs above apply regardless of tier; the subscription only affects how much you pay per credit.
If you cancel, any remaining discounted credits expire at the end of the current billing period.
