# 🗄️ ChromaDB Auth Proxy

A ChromaDB server with auth proxy.

## 🚀 Quick Start

### Connection Information
- **Host**: `https://hyperdemocracy.chromadb-usc-vecs.hf.space`
- **Authentication**: Secret bearer token

## 💻 Usage

### Python HttpClient Example
```python
import os
import time
import uuid

import chromadb
from chromadb.config import Settings, APIVersion

# Get host and token from environment variable
host = os.getenv("CHROMA_PROXY_BASE")
token = os.getenv("CHROMA_AUTH_TOKEN")
if not host or not token:
    raise ValueError("Set CHROMA_PROXY_BASE and CHROMA_AUTH_TOKEN")


headers = {"Authorization": f"Bearer {token}"}
settings = Settings(chroma_server_api_default_path=APIVersion.V2, anonymized_telemetry=False)
client = chromadb.HttpClient(host=host, headers=headers, settings=settings)

# Test the connection
print("HB:", client.heartbeat())

# Collection: create → add → query → delete
name=f"demo_{int(time.time())}_{uuid.uuid4().hex[:6]}"
coll=client.get_or_create_collection(name=name, metadata={"purpose":"smoke"})

coll.add(
    ids=["doc-1", "doc-2", "doc-3"],
    documents=[
        "The Eiffel Tower is located in Paris and was completed in 1889.",
        "Mount Fuji is the highest mountain in Japan and an active stratovolcano.",
        "The Great Wall of China is a series of fortifications built across ancient China.",
    ],
    metadatas=[
        {"country": "France", "city": "Paris"}, 
        {"country": "Japan"},
        {"country": "China"},
    ],
)

print(coll.query(query_texts=["Which landmark is in France?"], n_results=2))
client.delete_collection(name=name)
print("OK")

```

### curl example
```bash
# Test proxy health without authentication
curl https://hyperdemocracy-chromadb-usc-vecs.hf.space/health

# Test chromadb API with authentication
curl -H "authorization: Bearer $CHROMA_AUTH_TOKEN" https://hyperdemocracy-chromadb-usc-vecs.hf.space/api/v2/heartbeat
```
