Sign up, top up, and start API calls
The user flow is unified: create an account, sign in, top up, then use dashboard and API safely.
How top-up works: funds go into one shared wallet balance (USD), not model-specific packages. Use different model values in request JSON to call DeepSeek / GLM / Kimi lines.
