Steezn API

Public beta · v1

Detect, generate, and score fashion at scale.

The same models that power Steezn — wardrobe detection, AI outfit generation, and our proprietary steezeScore — exposed as three composable HTTP endpoints. Built for marketplaces, retail apps, and styling tools that don't want to roll their own fashion ML.

POST/v1/detect

Clothing detection

Image in, structured items out: category, subcategory, brand, color, season, style tags, bounding box, confidence. Tuned for retail and marketplace data models.

curl https://api.steezn.xyz/v1/detect \
  -H "Authorization: Bearer $STZN_API_KEY" \
  -F "image=@look.jpg"
Sample response
{
  "request_id": "req_8a1f2c…",
  "items": [
    {
      "category": "tops",
      "subcategory": "t-shirt",
      "brand": "Uniqlo",
      "colors": ["white"],
      "season": ["spring", "summer"],
      "style_tags": ["minimal", "casual"],
      "bbox": [120, 80, 380, 520],
      "confidence": 0.94
    },
    {
      "category": "bottoms",
      "subcategory": "denim",
      "colors": ["indigo"],
      "season": ["all"],
      "bbox": [110, 540, 400, 1100],
      "confidence": 0.89
    }
  ],
  "model": "stzn-detect-1",
  "billed_credits": 1
}
POST/v1/outfits

Outfit generation

Inventory + context (weather, occasion, formality, vibe) in, ranked outfit combinations out — with reasoning. Drop into "complete the look" widgets, virtual stylist flows, dressing-room apps.

curl https://api.steezn.xyz/v1/outfits \
  -H "Authorization: Bearer $STZN_API_KEY" \
  -d '{"items":[...],"context":{"weather":"15°C","activity":"brunch"}}'
Sample response
{
  "request_id": "req_4b32e1…",
  "outfits": [
    {
      "items": ["i1", "i2", "i3"],
      "rationale": "White tee + indigo denim + white sneakers — clean, weather-appropriate.",
      "score": 8.4,
      "context_match": { "weather": 0.92, "activity": 0.88 }
    },
    {
      "items": ["i4", "i2", "i3"],
      "rationale": "Linen shirt swap for a more elevated brunch read.",
      "score": 7.9
    }
  ],
  "billed_credits": 1
}
POST/v1/score

Style scoring

Outfit (image or item list) in, multi-dimensional score out: coherence, seasonality, formality, boldness, occasion fit — and our 0–10 steezeScore. Powers raters, filters, peer-review tools.

curl https://api.steezn.xyz/v1/score \
  -H "Authorization: Bearer $STZN_API_KEY" \
  -F "image=@outfit.jpg"
Sample response
{
  "request_id": "req_c0de…",
  "scores": {
    "coherence": 0.82,
    "seasonality": 0.91,
    "formality": 0.45,
    "boldness": 0.30,
    "occasion_fit": { "brunch": 0.88, "office": 0.21 },
    "steeze_score": 7.6
  },
  "explanation": "Clean palette, balanced proportions. Light on accessories — try one statement piece.",
  "billed_credits": 1
}
