API Documentation

Would rather not write an integration? The try-on widget installs with a single <script> tag on your storefront — no backend, no API calls.

Authentication

Pass your API key in the X-Api-Key. Keys start with the prefix tn_live_.

X-Api-Key: tn_live_xxxxxxxxxxxxxxxx

Credit Model

Every B2B feature deducts credits from your current-period quota at submission time. Credits are auto-refunded on permanent failure — no manual action required.

Feature	Credit formula
Try-On	1 credit per call
Description	1 credit per call
Model Shoot	variants × 3 + (2 if generated model) + (1 if custom background)
Video	per duration: 5s = 1, 8s = 2, 10s = 3, 15s = 4 (admin-managed)
Try-On Video	per duration: 5s = 1, 8s = 2, 10s = 3, 15s = 4 (separate tryon_video balance)

Refunds: permanent provider failure → full auto-refund; transient (internally retried) → no refund; model-shoot QA failure → non-refunding (a generation occurred).

Image Upload

POST /api/v1/b2b/uploads/ — multipart upload of one image (field file; JPEG, PNG or WebP, max 10 MB). Costs no credits. Returns an upload_id (pass as garment_upload_id) and a public url (usable as any *_image_url). You need this because every submit endpoint accepts only public HTTPS URLs — with this you no longer have to host images yourself. The id stops resolving after expires_in seconds.

curl -X POST https://api.try-nova.shop/api/v1/b2b/uploads/ \
  -H "X-Api-Key: tn_live_..." \
  -F "file=@garment.jpg"

# => { "data": { "upload_id": "9f2c...", "url": "https://...", "expires_in": 900 } }
# Pass upload_id as garment_upload_id, or use url as garment_image_url.

Pose & Background Catalogue

GET /api/v1/b2b/public/presets/ — no auth required. Returns the valid pose_preset_ids and background_preset values with preview cards and labels. Fetch these rather than hardcoding them: the catalogue changes, and an unknown id is a 400. Query params: locale (ru/en) and gender (male returns the male pose set; backgrounds are gender-agnostic).

# No API key needed — this is a public catalogue.
curl "https://api.try-nova.shop/api/v1/b2b/public/presets/?locale=en&gender=female"

# => { "data": { "version": 3, "gender": "female",
#      "poses":       [{ "id": "front_full", "label": "Front", "image_url": "..." }, ...],
#      "backgrounds": [{ "id": "studio_white", "label": "White studio", ... }, ...] } }

Your Own Models (saved models)

POST /api/v1/b2b/models/generate/ — mint a model to your spec (async; charges the generate surcharge, default 2 credits). Poll GET /api/v1/b2b/models/jobs/{request_id}/, then pass model.uuid as saved_model_id with model_source="saved" — reuse after that is free. List them with GET /api/v1/b2b/models/. This is also the answer when the stock library has no model of the type you need.

# 1. Generate a model (async, charges the generate surcharge once)
curl -X POST https://api.try-nova.shop/api/v1/b2b/models/generate/ \
  -H "X-Api-Key: tn_live_..." \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{"gender":"male","ethnicity":"south_asian","body_type":"athletic","age_range":"25-30","name":"Hero model"}'

# 2. Poll until status is "completed"
curl https://api.try-nova.shop/api/v1/b2b/models/jobs/<request_id>/ \
  -H "X-Api-Key: tn_live_..."

# 3. Reuse the model.uuid on any shoot or video — free from here on
curl -X POST https://api.try-nova.shop/api/v1/b2b/model-shoot/ \
  -H "X-Api-Key: tn_live_..." -H "Content-Type: application/json" \
  -d '{"garment_image_url":"https://...","model_source":"saved","saved_model_id":"<uuid>","model_gender":"male","pose_preset_ids":["front_full"],"variant_count":1}'

Virtual Try-On (VTO)

POST /api/v1/b2b/tryon/ — submit a try-on task. output_format=image (1 credit) or output_format=video (animated clip; charged from the separate tryon_video balance by duration — pass video_duration_seconds and motion_type). Use Idempotency-Key to prevent duplicates. Status: GET /api/v1/b2b/tryon/{request_id}/ (result_image_url is the VTO frame/poster, result_video_url is the finished video).

# Image output (1 credit)
curl -X POST https://api.try-nova.shop/api/v1/b2b/tryon/ \
  -H "X-Api-Key: tn_live_..." \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: unique-request-id" \
  -d '{"body_image_url":"https://...","garment_image_url":"https://..."}'

# Video output (charged from the tryon_video balance by duration)
curl -X POST https://api.try-nova.shop/api/v1/b2b/tryon/ \
  -H "X-Api-Key: tn_live_..." \
  -H "Content-Type: application/json" \
  -d '{"body_image_url":"https://...","garment_image_url":"https://...","output_format":"video","video_duration_seconds":8,"motion_type":"turn"}'

Product Description Generation

POST /api/v1/b2b/tools/description/ — generate an SEO product description (1 credit). Supports Wildberries, Ozon, etc.

curl -X POST https://api.try-nova.shop/api/v1/b2b/tools/description/ \
  -H "X-Api-Key: tn_live_..." \
  -H "Content-Type: application/json" \
  -d '{"product_name":"Denim Jacket","product_attributes":{"color":"blue","size":"M"},"platform":"wildberries"}'

Model Shoot — Generate model photoshoot

POST /api/v1/b2b/model-shoot/ — generate product images on a model. Cost: variants × 3 + 2 (if model_source=generate) + 1 (if background_custom_url). Status: GET /api/v1/b2b/model-shoot/{request_id}/.

# You need a saved_model_id first — see "Your Own Models" above.
# model_source "stock" is retired and returns 400 STOCK_MODELS_UNAVAILABLE.
# pose_preset_ids must be DISTINCT and its length must equal variant_count;
# fetch valid pose/background ids from /api/v1/b2b/public/presets/.
curl -X POST https://api.try-nova.shop/api/v1/b2b/model-shoot/ \
  -H "X-Api-Key: tn_live_..." \
  -H "Content-Type: application/json" \
  -d '{"garment_image_url":"https://...","model_source":"saved","saved_model_id":"<uuid>","model_gender":"female","model_ethnicity":"european","model_body_type":"average","model_age_range":"25-30","background_preset":"studio_white","pose_preset_ids":["front_full","three_quarter","profile","walking"],"lighting_preset":"studio_softbox","variant_count":4}'

Video Generation

POST /api/v1/b2b/video/ — generate an ad video. Supported durations and credit cost are admin-managed (defaults: 5s=1, 8s=2, 10s=3, 15s=4). Status: GET /api/v1/b2b/video/{request_id}/.

curl -X POST https://api.try-nova.shop/api/v1/b2b/video/ \
  -H "X-Api-Key: tn_live_..." \
  -H "Content-Type: application/json" \
  -d '{"garment_image_url":"https://...","model_gender":"female","duration_seconds":8,"aspect_ratio":"9:16"}'

Analytics & tracking

1. Add the tracking pixel

After you integrate the generation API, embed this once on every storefront page that shows a TryNova asset:

<script src="https://pixel.try-nova.shop/pixel.js" data-key="YOUR_PIXEL_KEY"></script>

Mark each rendered asset with the request_id you received at generation time:

<div data-trynova-asset="REQUEST_ID" data-trynova-sku="YOUR_SKU"> …asset… </div>

Consent: the pixel stores nothing and sends nothing until consent is granted. Either add data-consent="granted" to the script tag, or call TryNova.consent() after your own cookie/consent banner is accepted (TryNova.revoke() opts out). Impressions and views are then tracked automatically. Fire intent events yourself:

TryNova.track("add_to_cart", { assetId: "REQUEST_ID", sku: "YOUR_SKU" });

Purchases and returns are not sent from the browser (the pixel key is public) — see step 2.

2. Send purchases & returns server-side (required for revenue)

The pixel key is public — it's visible in your page source — so it can only send low-trust events (impressions / views / add-to-cart). Purchases and returns carry money, so they must come from your backend with a secret API key, never the pixel key:

curl -X POST https://api.try-nova.shop/api/v1/b2b/events/ \
  -H "X-Api-Key: YOUR_SECRET_KEY" -H "Content-Type: application/json" \
  -d '{"event_id":"order-1234","asset_id":"REQUEST_ID","sku":"YOUR_SKU","event_type":"purchase","value":4990,"currency":"RUB","occurred_at":"2026-06-23T12:00:00Z"}'

Include a stable event_id (e.g. your order id) so retries are idempotent. Use "event_type":"return" when an order is returned.

3. Selling on a marketplace (Wildberries / Ozon / Amazon)?

The pixel can't run on marketplace listing pages, so storefront analytics won't cover those sales yet. Connecting your marketplace account to read per-SKU views, orders, and returns is coming soon (a separate release).
