Set the model field to the exact slug shown above:
curl https://api.cheapaapi.com/v1/chat/completions \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "model": "deepseek-v3.2", "messages": [{"role": "user", "content": "Review this Python snippet for bugs."}] }' Slugs are case-sensitive . Kimi-K2.6 and kimi-k2.6 are not equivalent — use the lowercase slug exactly as shown.
curl https://api.cheapaapi.com/v1/models \ -H "Authorization: Bearer YOUR_API_KEY" Returns a standard ListModelsResponse object containing all model IDs currently available on the platform.
Token-priced models charge per one million tokens — input and output independently.
Image/video models charge a flat fee per successful generation (no token billing applies).
Actual charges scale proportionally — a request using 2,000 tokens costs (2,000 ÷ 1,000,000) × rate.
Context window is the combined maximum for prompt and completion tokens in a single call.
Model availability is subject to change; check the Models catalog for the current live list.
