1. Choose and Purchase an API Key
JuheNext Keys do not expire and are billed by model usage allowance. Current packages are ¥35 for ⚡10, ¥100 for ⚡30, and ¥280 for ⚡100.
- Open the Pricing page from JuheNext.
- Before purchasing, select a supported model and package in the calculator.
- Choose Buy Now on the matching package to open its payment page.
- Keys have no concurrency limit. Final charges follow the actual usage records.
2. Store Your Key Safely
Treat the delivered API Key like a password and store it in a trusted password manager.
- Do not publish the Key in screenshots, chat messages, frontend code, logs, or public repositories.
- Only enter the Key on trusted JuheNext pages and tools.
- If a Key may have been exposed, stop using it and contact support on WeChat: ACG508.
3. Choose a Model
The model catalog and prices are loaded from the current JuheNext database, so the live list is the final reference.
- Open Models to search the complete supported model list.
- Filter the Default, Standard, or Basic series and copy the exact model ID you plan to use.
- Review input, output, cache, per-request, and complete tiered pricing before starting a task.
- Compatible clients use Base URL:
- When required, append a version path:
/v1 or /v1beta. - OpenAI-compatible endpoint:
/v1/chat/completions - Messages endpoint:
/v1/messages - Gemini endpoint:
/v1beta/models/{{model}}:generateContent
4. Start an AI Chat
Use the chat tool for questions, writing, translation, analysis, and other everyday language tasks.
- Open Chat, launch the chat tool, and add your Key when prompted.
- Choose the exact model ID you reviewed on the Models page.
- Send a short test message first, then continue with the full task after confirming the response.
- Do not submit passwords, payment details, or unnecessary sensitive information to a model.
5. Create Images or Videos
Use the dedicated creation tool for image and video generation tasks that require prompts, aspect ratios, durations, or downloadable results.
- Open Create and select a currently supported generation model.
- Describe the subject, action, style, lighting, composition, aspect ratio, or duration as clearly as possible.
- Keep the task page open until processing finishes and use the returned file link to download the result.
- Video billing rules vary and are not included in the Pricing calculator. Check the final charge in Usage.
6. Connect through the API
JuheNext provides an OpenAI-compatible interface at https://api.juhenextvip.com.
- Open Docs for authentication, endpoint, streaming, and request examples.
- Keep the Base URL and API Key in server-side environment variables.
- Send the Key with the Authorization: Bearer header and use an exact model ID from Models.
- Never expose a production Key in browser JavaScript or commit it to a repository.
curl https://api.juhenextvip.com/v1/chat/completions \
-H "Authorization: Bearer sk-your-key" \
-H "Content-Type: application/json" \
-d '{
"model": "gpt-5.6-luna",
"messages": [
{
"role": "user",
"content": "Hello"
}
]
}'7. Check Usage and Logs
The public lookup page can check a Key without creating an account. The submitted Key is used only for the current request and is not intentionally stored by the public website.
- Open Usage and enter the Key to view its allowance and recent activity.
- Review total allowance, used allowance, remaining balance, and recent calls.
- Usage logs include charges and refunds; cached tokens are included with input tokens in the displayed totals.
- CSV exports match the visible log fields and use ⚡ as the charge unit.
8. Troubleshooting
- Authentication failed: confirm that the Key is complete and the Authorization header uses Bearer.
- 429 or temporary 5xx: wait and retry with a limited count and exponential backoff.
- Model unavailable: copy a currently listed model ID from Models.
- Unexpected charge: check the model, pricing tier, request type, refunds, and recent Usage logs.
