Example use cases
Example prompt
“Walk me step-by-step through why the Monty Hall problem gives a 2/3 probability of winning if you switch — I want the full chain-of-thought reasoning, not just the answer.”
Technical details
Endpoint
POSThttps://minichan.vercel.app/api/reasoningWhen to prefer
Choose this endpoint when you need deep, step-by-step chain-of-thought reasoning rather than a direct answer — ideal for math problems, logical puzzles, complex technical questions, root cause analysis, or multi-step inference. Prefer this over the general text endpoint when the problem structure requires intermediate reasoning steps to be surfaced. The 428B MoE model provides high-quality reasoning at a fixed cost of $0.15 USDC per call via x402 on Base.
Side effects
- Missing required 'prompt' field returns a 400 validation error
- Payment not sent or insufficient USDC via x402 returns a 402 Payment Required
- Model timeout on extremely long or complex prompts may result in a 504 or truncated response
- Vague or ambiguous prompts may yield shallow reasoning rather than deep chain-of-thought
- Rate limiting or quota exceeded returns a 429 error
