A little meaning, in numbers.

Send JSON to https://embedder.sontent.com/embed with your x-api-key header. Keep the key on your backend; do not ship it in public frontend code.

export BASE_URL="https://embedder.sontent.com"
export API_KEY="your-api-key"

curl --fail-with-body --max-time 5 "$BASE_URL/embed" \
  -H "Content-Type: application/json" \
  -H "x-api-key: $API_KEY" \
  -d '{"text":"Pflanzen betreiben Photosynthese.","dimensions":256}'

# pip install httpx; set API_KEY in your environment
import asyncio
import os
import httpx

BASE_URL = os.getenv("BASE_URL", "https://embedder.sontent.com")

async def main():
    async with httpx.AsyncClient(timeout=5.0) as client:
        response = await client.post(
            f"{BASE_URL.rstrip('/')}/embed",
            headers={"x-api-key": os.environ["API_KEY"]},
            json={"text": "Pflanzen betreiben Photosynthese.", "dimensions": 256},
        )
        response.raise_for_status()
        vector = response.json()["embedding"]
        print(vector)

asyncio.run(main())

The server allows one second, including time waiting for the encoder. The five-second client timeout leaves room for network travel and the server’s error response. Use 256 dimensions for retrieval; smaller vectors are experimental.
