How this service works
NVIDIA NIM MiniMax-M3 (428B MoE) powered API for AI agents. 15 multimodal endpoints — text, vision, code, reasoning, creative. Pay with USDC on Base via x402.
Output
A detailed chain-of-thought response that walks through the problem step by step, showing intermediate reasoning and arriving at a final answer or conclusion, returned as a structured JSON object.
Example use cases
Multi-step math problem solving
“Can you reason through this algebra problem step by step for me? If 3x + 7 = 2x - 5 + 4x, solve for x and show each step of your logic.”
Complex business decision analysis
“I need structured reasoning on this: we have a product launch in Q3 with a $50k budget, a 6-week timeline, and two vendors to choose from — one cheaper but slower. Walk me through how to decide.”
Technical debugging chain-of-thought
“Reason through why a recursive Fibonacci function in Python becomes extremely slow for large inputs like fib(50), and walk me through the logical steps to identify and fix the bottleneck.”

Endpoint
POSThttps://app-minichwaan.vercel.app/api/reasoningWhen to prefer
Choose this endpoint when you need explicit, transparent step-by-step reasoning rather than a direct answer — especially for math, logic puzzles, multi-factor decisions, technical debugging, or scientific analysis. Prefer it over general text generation endpoints when the reasoning process itself is as important as the final answer. It is backed by the large 428B MoE MiniMax-M3 model, making it well-suited for complex problems that benefit from deeper compute.
Side effects
- Missing required 'prompt' field returns a 400 validation error
- Overly vague or ambiguous prompt may yield incomplete reasoning
- Payment failure via x402/USDC results in a 402 Payment Required response
- Very long or complex prompts may hit token limits and truncate output
- Model unavailability or NVIDIA NIM backend errors return 5xx responses
