Skinbase Vision Stack (CLIP + BLIP + YOLO + Qdrant + Card Renderer + Maturity) – Dockerized FastAPI

This repository provides six standalone vision services (CLIP / BLIP / YOLO / Qdrant / Card Renderer / Maturity) and a Gateway API that can call them individually or together.

Services & Ports

• gateway (exposed): https://vision.klevze.net
• clip: internal only
• blip: internal only
• yolo: internal only
• qdrant: vector DB (port 6333 exposed for direct access)
• qdrant-svc: internal Qdrant API wrapper
• card-renderer: internal card rendering service
• maturity: internal NSFW/maturity classifier service

Run

docker compose up -d --build

If you use BLIP, create a .env file first.

Required variables:

API_KEY=your_api_key_here
HUGGINGFACE_TOKEN=your_huggingface_token_here

HUGGINGFACE_TOKEN is required when the configured BLIP model is private, gated, or otherwise requires Hugging Face authentication.

Optional maturity configuration (override in .env if needed):

MATURITY_MODEL=Falconsai/nsfw_image_detection
MATURITY_THRESHOLD_MATURE=0.80
MATURITY_THRESHOLD_REVIEW=0.60
MATURITY_ENABLED=true

Service startup now waits on container healthchecks, so first boot may take longer while models finish loading.

Maturity / NSFW analysis

Analyzes an image and returns a normalized maturity signal for Nova moderation workflows.

Analyze by URL

curl -H "X-API-Key: <your-api-key>" -X POST https://vision.klevze.net/analyze/maturity \
  -H "Content-Type: application/json" \
  -d '{"url":"https://files.skinbase.org/img/aa/bb/cc/md.webp"}'

  -F "file=@/path/to/image.webp"

Example response:

{
  "maturity_label": "mature",
  "confidence": 0.94,
  "score": 0.94,
  "labels": ["nsfw"],
  "model": "Falconsai/nsfw_image_detection",
  "threshold_used": 0.80,
  "analysis_time_ms": 183.0,
  "source": "maturity-service",
  "action_hint": "flag_high",
  "advisory": "High-confidence mature content detected"
}

action_hint values: safe, review, flag_high. Nova should use these to decide blur/queue/flag behaviour.

Vector DB (Qdrant) via gateway

Qdrant point IDs must be either:

• an unsigned integer
• a UUID string

If you send another string value, the wrapper may replace it with a generated UUID. In that case the original value is stored in the payload as _original_id.

You can fetch a stored point by its preserved original application ID:

curl -H "X-API-Key: <your-api-key>" https://vision.klevze.net/vectors/points/by-original-id/img-001

Store image embedding by URL

curl -H "X-API-Key: <your-api-key>" -X POST https://vision.klevze.net/vectors/upsert \
  -H "Content-Type: application/json" \
  -d '{"url":"https://files.skinbase.org/img/aa/bb/cc/md.webp","id":"550e8400-e29b-41d4-a716-446655440000","metadata":{"category":"wallpaper"}}'

Store image embedding by file upload

curl -H "X-API-Key: <your-api-key>" -X POST https://vision.klevze.net/vectors/upsert/file \
  -F "file=@/path/to/image.webp" \
  -F 'id=550e8400-e29b-41d4-a716-446655440001' \
  -F 'metadata_json={"category":"photo"}'

Search similar images by URL

curl -H "X-API-Key: <your-api-key>" -X POST https://vision.klevze.net/vectors/search \
  -H "Content-Type: application/json" \
  -d '{"url":"https://files.skinbase.org/img/aa/bb/cc/md.webp","limit":5,"filter_metadata":{"is_public":true}}'

Optional search parameters: hnsw_ef (int), exact (bool), indexed_only (bool), score_threshold (float), filter_metadata (object).

curl -H "X-API-Key: <your-api-key>" -X POST https://vision.klevze.net/vectors/search/file \
  -F "file=@/path/to/image.webp" \
  -F "limit=5" \
  -F 'filter_metadata_json={"is_public":true}'

List collections

curl -H "X-API-Key: <your-api-key>" https://vision.klevze.net/vectors/collections

Returns HNSW config, optimizer config, quantization, segment count, payload index coverage, and RAM estimate for every collection.

Payload index management

# List indexes
curl -H "X-API-Key: <your-api-key>" https://vision.klevze.net/vectors/collections/images/indexes

# Create a single index
curl -H "X-API-Key: <your-api-key>" -X POST https://vision.klevze.net/vectors/collections/images/indexes \
  -H "Content-Type: application/json" \
  -d '{"field":"is_public","type":"bool"}'

# Ensure multiple indexes (idempotent)
curl -H "X-API-Key: <your-api-key>" -X POST https://vision.klevze.net/vectors/collections/images/ensure-indexes \
  -H "Content-Type: application/json" \
  -d '{"fields":[{"field":"is_public","type":"bool"},{"field":"category_id","type":"integer"}]}'

If you let the wrapper generate a UUID, use the returned id value for later get, search, or delete operations.

Notes

• Models are loaded at service startup; initial container start can take 1–2 minutes as model weights are downloaded.
• Qdrant data is persisted in the project folder at ./data/qdrant, so it survives container restarts and recreates.
• Remote image URLs are restricted to public http/https hosts. Localhost, private IP ranges, and non-image content types are rejected.
• The maturity service uses Falconsai/nsfw_image_detection (ViT-based). Thresholds are configurable via .env. The model handles photos and stylized digital art but should be calibrated against real Skinbase content before production use.
• For production: add auth, rate limits, and restrict gateway exposure (private network).
• GPU: you can add NVIDIA runtime later (compose profiles) if needed.
