# MiniChan Reasoning Endpoint — NVIDIA NIM MiniMax-M3

> MiniChan Reasoning Endpoint — NVIDIA NIM MiniMax-M3 is a paid API for AI agents from minizzzan.vercel.app, paid per call via x402, $0.15/call, status unknown (last checked 2026-09-15).

Performs step-by-step chain-of-thought reasoning on complex problems or questions using the MiniMax-M3 428B MoE model via NVIDIA NIM, payable in USDC on Base.

## Facts

- Endpoint: POST https://minizzzan.vercel.app/api/reasoning
- Price: $0.15/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability minichan-reasoning-endpoint-nvidia-nim-minimax-m3-dfcae0d5 -d '<json body>'
```

Example prompt: Walk me through step-by-step reasoning on this problem: 'A snail climbs 3 feet up a 10-foot pole each day but slides back 2 feet each night — how many days does it take to reach the top?' I need each reasoning step explained clearly.

## When to prefer this

Choose this endpoint when you need explicit chain-of-thought or step-by-step reasoning over a problem, especially for math, logic, or multi-step analytical questions — particularly when paying per-call with USDC via x402 is acceptable and you want a very large MoE model (428B parameters) without managing inference infrastructure.

## Known failure modes

- Missing required 'prompt' field returns a 400 validation error
- Payment not provided or insufficient USDC results in 402 Payment Required
- Prompt too long may exceed model context window and return an error
- Model inference timeout on extremely complex problems
- NVIDIA NIM backend unavailability returns 503
