Fittins AI API
Premium AI fashion photos and videos, made from your own system
The Fittins AI API puts your products on AI models from your store, catalogue system or agency tools. Send up to 3 product photos and pick a model: a studio-quality on-model photo up to 8K comes back in about a minute, or a fashion video up to 4K in a few minutes, from the same premium engine as fittins.ai.
Included in the Pro, Business, Enterprise plans, from $27 a month for the Pro plan. The same credits as the website: a Default 1K photo is 40 credits.

Is there an API for AI fashion model photos?
Yes. The Fittins AI API creates premium on-model photos and fashion videos of your products from your own system: send product photos and an AI model, get a studio-quality PNG up to 8K or an MP4 up to 4K. Included in the Pro, Business, Enterprise plans, from $27 a month for the Pro plan. It uses the same credits as the website: a Default 1K photo is 40 credits.
A premium engine, built for production
Fittins AI is a premium AI fashion generation service for on-model photos, virtual try-on and fashion videos. It turns your product photos into studio-quality images up to 8K and videos up to 4K, with Premium and Ultra quality tiers, custom AI models and custom locations.
Studio quality up to 8K
Turbo, Default, Premium and Ultra tiers, at 1K, 2K, 4K or 8K. PNG files ready for any store or marketplace.
Fashion video up to 4K
5 or 10 second videos of your products on AI models, vertical, square or wide, with optional AI sound.
Your brand look
Use our model library, or your own custom models and locations, so the same face and setting runs through your catalogue.
Built for production
Signed webhooks, a queue when you send a lot at once, safe retries, test keys that never charge, and errors that name the field.
Charged only for results
The same credits as the website, taken once when the result is saved. A refused or failed generation costs nothing. Set a monthly cap per key.
In your library too
Every API result also appears in My Generations on fittins.ai, with an API badge and your own reference, such as the SKU.
Private by design
Keys are stored as hashes, files come through signed links, and responses never include our internal data or storage addresses.
How it works
- 1
Create a key
In Profile → API keys on fittins.ai, on the Pro plan or higher.
- 2
Send a product photo
POST /v1/images with your photo URL, a model and a short prompt. It answers at once with a generation id.
- 3
Get the photo
Get a webhook, or check the generation, and download the full-quality PNG.
What teams build with it
- New products in your store or PIM get on-model photos as they are added.
- One custom model across a whole collection, for a consistent brand look.
- Marketplace-ready photos for Amazon, Etsy and Shopify, in their aspect ratios.
- Short product videos for ads and social media, made as new items arrive.
- Agencies producing on-model photos and videos for many brands from one system.
Made with the same engine
Real on-model photos made with Fittins AI from product photos.

Frequently asked questions
Which plans include the API?
Included in the Pro, Business, Enterprise plans, from $27 a month for the Pro plan.
Does the API cost more than the website?
No. It uses the same credits: from 30 credits for a Turbo 1K photo to 100 for Ultra 8K, 40 at the Default 1K setting. Credits are taken only when the photo is saved.
Where do the results go?
The API returns a download link to the full-quality PNG or MP4, and each result is also saved to My Generations on fittins.ai with an API badge, so the team can see and download everything in one place.
What product photos work?
Flat lays, hanger and ghost-mannequin shots and packshots, as PNG, JPEG or WebP up to 10 MB: 1 to 3 photos of the same item per generation. Another colour of the same item goes in a separate generation.
Can I use my own models?
Yes. Use custom models and locations you made on fittins.ai by id, or create new ones through the API from a description or a reference photo.
Is there video in the API?
Yes. POST /v1/videos makes a 5 or 10 second fashion video up to 4K, with optional AI sound. A Default 5 second video is 130 credits.
Do I have to keep checking for results?
No. Register a webhook and we send a signed event when each generation finishes, with automatic retries. You can also check a generation at any time.
Can I test it without spending credits?
Yes. Test keys run the checks on your request and return a sample result, without using the AI or any credits.
Is it safe to send our product photos?
Photos are copied into your own account's library, keys are stored only as hashes, and files are served through signed links that expire. Your results are yours, like on the website.
