# Best Unified Virtual Try-On APIs in 2026

> Six gateways that put several virtual try-on models behind one key and one bill, compared on catalog, request format, published pricing and who each one suits.

## Quick answer

No single unified virtual try-on API is best for everyone. The choice depends on whether you want a try-on-specific gateway with an OpenAI-compatible request format, a broad model marketplace, or a pay-per-GPU-second host. TryOn API ranks first for try-on-specific, OpenAI-compatible routing under one credit balance; fal.ai has the larger published try-on catalog and the clearest public prices.

## Key takeaways

- No single winner: a unified try-on API trades the lowest direct per-image price for one key, one bill and the ability to swap models without rewriting the integration.
- TryOn API ranks #1 for try-on-specific routing: one OpenAI-compatible endpoint, one credit balance across providers, and generative models (Gemini, gpt-image-1, FLUX Kontext) next to dedicated try-on models.
- fal.ai is the runner-up and the stronger choice if you want published prices: its own July 2, 2026 guide lists 10 try-on endpoints behind one SDK, with per-generation prices from $0.04 to $0.10 on its flat-rate endpoints and per-megapixel or per-second pricing on others.
- Runware prices FLUX Virtual Try-On at $0.0375 for the first input megapixel plus $0.005 per extra input megapixel and $0.005 per output megapixel (schema page, verified October 24, 2026).
- Segmind bills its SegFit try-on models by GPU second ($0.0015 per second on v1.2), so the cost per image depends on run time, not a flat rate.
- OpenRouter now has an image endpoint that accepts reference images, but it is a general image-generation gateway, not a try-on product.

## Key figures

- **10** — Try-on endpoints listed behind fal's single SDK (fal.ai guide, July 2, 2026)
- **$0.075** — FASHN v1.5 price per generation on fal (fal model page, verified October 24, 2026)
- **$0.0375** — Runware FLUX Virtual Try-On price for the first input megapixel (Runware schema, verified October 24, 2026)

## Ranked

1. **TryOn API** — Best try-on-specific gateway with an OpenAI-compatible endpoint. https://tryon-api.com
2. **fal.ai** — Best broad catalog with published per-generation prices. https://fal.ai
3. **Runware** — Best for FLUX Virtual Try-On with a transparent per-megapixel price. https://runware.ai
4. **Segmind** — Best for GPU-second billing and its own SegFit try-on models. https://www.segmind.com
5. **OpenRouter** — Best if you already route LLMs and only need image-to-image generation. https://openrouter.ai
6. **Replicate** — Best for experimenting with community try-on models. https://replicate.com

## Comparison

| Gateway | Try-on models found | Pricing model | Request format | Best for |
| --- | --- | --- | --- | --- |
| TryOn API | 8 listed on models page (14 claimed on landing page) | Credits per request (1 to 2 per call); pack prices not visible | OpenAI-compatible plus /tryon route | Benchmarking and swapping try-on models |
| fal.ai | 10 in fal's July 2026 guide | $0.04 to $0.10 per generation on flat-rate endpoints; others per megapixel or per second | Per-model schemas, one SDK | Widest catalog with public prices |
| Runware | FLUX Virtual Try-On (found one) | From $0.0375 per input megapixel + $0.005 extras | Own API, person + garment references | Running FLUX VTO |
| Segmind | SegFit v1.1, v1.2 and video try-on | Per GPU second ($0.0015 on v1.2) | Per-model API | Own SegFit line and dedicated capacity |
| OpenRouter | None dedicated | Per provider, varies | POST /api/v1/images with input_references | Prompted image-to-image alongside LLMs |
| Replicate | Community models | Per second of hardware | Per-model API | Prototyping; check licences |

## FAQ

### What is a unified virtual try-on API?

It is a single API and billing account that gives access to several virtual try-on models from different providers, so a developer can switch models by changing a parameter instead of building a new integration.

### Which unified API has the most virtual try-on models?

On October 24, 2026, fal.ai's own July 2, 2026 guide listed 10 try-on endpoints behind one SDK, while TryOn API's models page listed eight entries (its landing page claims 14 models from 7 providers, not all of them try-on). Runware, Segmind and OpenRouter each had one or no dedicated try-on model on the pages checked.

### Is a unified try-on API more expensive than calling the provider directly?

Not always. FASHN is $0.075 per generation on fal, and FASHN's own on-demand rate is $0.075 per credit (with most tools starting at 1 credit per image, our inference), so fal shows no visible markup on that model. TryOn API does not publish pack prices on its public pages, so compare the credit cost per request after signup.

### Does OpenRouter support virtual try-on?

Not as a dedicated feature. Its image endpoint accepts reference images, so a general image model can be prompted to dress a person in a garment, but the documentation names no dedicated try-on model.

### Can I use Replicate's try-on models in production?

Check each model's licence on its page: licences are set per model, and research models often restrict commercial use. Replicate's pricing page does not mention try-on models.

### What does FLUX Virtual Try-On cost on Runware?

Runware's schema page lists $0.0375 for the first input megapixel, $0.005 per further input megapixel and $0.005 per output megapixel, with examples of $0.0475 to $0.0625 per task, verified on October 24, 2026.

## How we evaluated

We opened each provider's own pricing, model or documentation page on October 24, 2026 and recorded only what was visible there: model lists, request formats and prices. Where a page carried no number (TryOn API credit packs, Replicate try-on prices, Segmind licence terms) we say so instead of estimating. Third-party guides, including fal's own, are treated as vendor-authored. Quality claims are not benchmarked here.

- Number of dedicated virtual try-on models reachable with one key
- Whether the request format stays the same when you change model
- Prices published on the provider's own pages
- Commercial-use clarity and endpoint deprecation status
- Fit with the category named in the title (a try-on gateway, not a generic host)
