JuheAPI Multi-Model Routing

Unified Access via Wisdom-Gate

JuheAPI enables developers to route requests dynamically to different models with a single endpoint, simplifying experimentation and deployment.

API Example

Use the Wisdom-Gate Chat Completions endpoint:

curl --location --request POST 'https://wisdom-gate.juheapi.com/v1/chat/completions' \
--header 'Authorization: YOUR_API_KEY' \
--header 'Content-Type: application/json' \
--header 'Accept: */*' \
--header 'Host: wisdom-gate.juheapi.com' \
--header 'Connection: keep-alive' \
--data-raw '{
    "model":"claude-sonnet-4-5-20250929",
    "messages": [
      {
        "role": "user",
        "content": "Hello, how can you help me today?"
      }
    ]
}'
