semantic search API for app

Could you clarify what you need by “semantic search API for app”?

I can help in a few ways:

1. Design an API for semantic search
2. Recommend tools/services to use
3. Write backend code for an API endpoint
4. Design a vector database schema
5. Help integrate it into your app

If you want, I can give you a quick starter design like:

Example semantic search API

Endpoint: POST /search

{
  "query": "wireless noise cancelling headphones",
  "filters": {
    "category": "electronics",
    "price_max": 300
  },
  "top_k": 10
}

Response:

{
  "results": [
    {
      "id": "prod_123",
      "title": "Sony WH-1000XM5",
      "score": 0.92,
      "snippet": "Premium wireless noise cancelling headphones..."
    }
  ]
}

Typical implementation:

• Create embeddings for your content
• Store them in a vector DB like Pinecone, Weaviate, Milvus, pgvector
• Embed the user query
• Run nearest-neighbor similarity search
• Optionally rerank results with an LLM or cross-encoder

If you tell me your stack (e.g. Node.js, Python, Firebase, PostgreSQL) and what you’re searching (products, docs, chat, images), I can build the API spec or code for you.
